unity3d版本更新日志

What's new in Unity 4.1.2:

March 26th, 2013

Features:
· Web Player: Secret information can now be injected into a running web player via Javascript, with access to that information controlled by cryptographic signatures. Security.GetChainOfTrustValue can be used to retrieve this secret information, provided that the Security object is called from an assembly whose cryptographic signature is valid and matches the signature passed in when the secret is injected. For further information, see the Manual.

Improvements:
· Android: Stylus support .
· UI: Windows can now be displayed modally using the GUI.ModalWindow call. Modal windows appear on top of all other Unity GUI elements and prevent interaction with all Unity GUI elements not within the modal window while open. Only one modal window can be open during a frame.

Fixes:
· Android: Fixed touch and stylus input on devices having a single surface emitting both at the same time.
· Android: Fixed performance regression with static batching.
· Android: Added a workaround for android issue 41755 - ANR when using apple magic mouse.
· Android: Fixed an issue where "Stream from disc" audio was really slow when used with the "Split Application Binary" option.
· Android: Fixed an issue where "Stream from disc" audio was broken when used with the "Split Application Binary" option.
· DX11: Fixed GPU profiler not working (regression in 4.1).
· Fix Crash in libmono.so due to GC_abort.
· Fix ArgumentException: Invalid platform target" when trying to switch platform.
· Graphics: Fixed Graphics.activeColorBuffer, activeDepthBuffer etc. crash when there's no active render target (regression in 4.1).
· GUI: Modal GUI windows are now always on top of all other Unity GUIs, regardless of GUI.depth value.
· GUI: When right-clicking on a window, context-menu events are once again being fired properly.
· Native Client: Fixed "Development Player" label showing on non-development players.
· Shuriken: Fixed an issue where particle rotations were broken.
· Social API: Fixed problem loading leaderboard scores in Mac OS X 10.8 GameCenter.
· UnityEngine.dll and UnityEditor.dll are no longer signed/strong-named. Compiled assemblies can once again reference the UnityEditor and UnityEngine namespaces.
· Web Player: Chain of Trust system now requires signed assemblies to be loaded with new Security.LoadAndVerifyAssembly method in order to be eligible to call Security.GetChainOfTrustValue. Values stored in the Chain of Trust are still only accessible to assemblies signed with the specified public key.
· Webplayer: Fixes a bug where using the WWW class in the web player would cause 50ms hiccups for each instance.
· Webplayer: Application.ExternalEval and Application.ExternalCall will now properly escape Javascript strings with embedded escape sequences.

What's new in Unity 4.1.0:

March 14th, 2013

Features:
· Profiler: Memory profiler makes it posible to view a snapshot of currently loaded game objects and assets, and shows the reason why an object is in memory. Memory usage of a player can also be viewed by connecting to the player from the editor.
· Simple vs. Complex view type dropdown button in the memory area.
· Substance: Procedural textures are now supported at runtime on iOS and Android (ARM v7a only with NEON extension only).
· Mecanim: 2D Blend Nodes for Blend Trees. 2D Blend Nodes are like regular blend nodes except you can blend based on two float parameters instead of one. Supported 2D blend types are Simple Directional, Freeform Directional, and Freeform Cartesian.
· Graphics: Custom Material Editors! A shader can have CustomEditor keyword which points to an editor class that derives from MaterialEditor. This is useful for setting per material shader keywords from the UI.
· Graphics: Per-material shader keywords. You can now set shader keyworkds on a per material basis. This allows for less work maintaining shaders and turning on and off parts of a shader with keywords.
· iOS: full multi-screen support (AirPlay). Look for added Display class for an array of connected displays (only iOS is properly implemented now - all other platforms will have only one display in there).
· Mac OS X Standalone: added GameCenter support.
· Graphics: Rendering with shader replacement now supports lighting. If you render a camera with a replacement shader, the camera will pick the shader that corresponds to the current camera rendering path (forward / deferred / vertex lit).
· Graphics: Camera.SetTargetBuffers added, allowing you to set buffers to draw to from RenderTexture or from screen; or to share depth buffer between different cameras.
· Added Transform.hasChanged flag that can be used to check if the transform's position/rotation/scale has been altered since the last time hasChanged was set to 'false'.
· Audio: Added scripting API support for sample-precision stitching of audio clips and synchronized DSP effects (AudioSettings.dspTime, AudioSource.PlayScheduled, AudioSource.SetScheduledStartTime, AudioSource.SetScheduledEndTime)
· Editor: Console can now be filtered by Errors, Warnings, and Logs.
· Shadows: Hardware shadow map filtering on capable mobile platforms (EXT_shadow_samplers; most recent iOS devices, very few Android devices yet). Makes shadow edges look a bit nicer, at some performance cost (used only when Light has shadows set to "Soft").
· Mecanim: API for recording.
· Mecanim: Can now change AnimatorController at runtime.

Improvements:
· Android: Added caching of shader binaries for faster load time, if available in the GLES driver (GL_OES_get_program_binary extension).
· Android: Propagation of native crashes (callstack etc.) to the Google Play Error Reporter. This include native plugins and script callstacks.
· Android: Added multiple render target support on NVIDIA (GL_NV_draw_buffers and GL_NV_fbo_color_attachments).
· Audio: Added AudioSource.ignoreListenerPause to enable playback of sounds in menus and editor extensions while AudioListener.pause=true
· Audio: It is now possible to query play position and Microphone read position from a different thread than the main thread. This can be used to lower the latency of processing microphone input, by adaptively regulating playback speed.
· Editor: Scene view can be set to render with shader replacement, SceneView.SetSceneViewShaderReplace.
· Editor: CustomEditors can now optionally apply for subclasses of the class they're editing. Use [CustomEditor(typeof(MyClass), true)] to also make a custom editor work for MyClass' children
· Editor: Confirmation for losing prefab connection now only comes up once when dragging multiple child objects out of a prefab.
· Editor: Display Unity version in Project Wizard dialog title.
· Editor: Files with the FNT extension will now be imported as TextAssets (before they were of unknown type).
· Editor: It's now possible to move MonoBehaviours from one game object to another via drag & drop.
· Graphics: Added depth parameter to GL.Clear, for cases when you want to clear depth buffer to non-1.0 value.
· Graphics: Added SystemInfo.maxTextureSize.
· Graphics: ARGBHalf, RGHalf, RHalf, R8 render texture formats supported on modern OpenGL & OpenGL ES 2.0 devices.
· Graphics: Improved handling of non-power-of-two texture sizes.
· On most platforms, a NPOT-sized texture without mipmaps and with Clamp wrapping mode will be actually represented as NPOT size texture on the GPU. This lowers memory usage and greatly improves loading times for NPOT texture sizes.
· NPOT-sized uncompressed textures with mipmaps are faster as well, if the GPU supports arbitrary texture sizes (most modern PC GPUs do).
· Added SystemInfo.npotSupport.
· Input: You can now control which layers get OnMouse* events via Camera.eventMask. Setting it to zero turns off the mouse events, improving performance.
· Installers: New icons and other artwork for OS X installers.
· iOS: "iPhoneBundleIdentifier not set up" demoted to warning.
· iOS: Device physical architecture is reported more accurately, though in lowercase (like 'armv7s').
· iOS: Info.plist now will be appended instead of overwriting it.
· iOS: Minor PhysX performance improvements.
· iOS: Total amount of physical memory is reported more accurately.
· Linux: Associate project icon with player window.
· Linux: Implement nographics batch mode.
· Linux: Statically link libstdc++ for greater compatibility with older installations.
· Mecanim: AssetBundles work with Mecanim.
· Mecanim: Ability to drag States and StateMachines into sub StateMachines.
· Mecanim: Mirror and Cycle offset available on States and BlendTree leafs (no need to duplicate animation for mirroring anymore).
· Mecanim: Allow multi-editing of Animator components.
· Mecanim: Context menu to delete States and StateMachines.
· Mecanim: Copy Paste of State/StateMachine also copies missing parameters.
· Mecanim: Transitions are only reorderable in the context of a State.
· Profiler: It is now possible to connect to a player by manually typing the IP of the device where the player is running - in case of multiple players on the same IP, it will connect to the player listening on the lowest port (which is randomly assigned).
· Resources.UnloadUnusedAssets() has been rewritten. It is around 4x faster than in Unity 4.0 and works much better in a game that streams levels in and out. The unloading is now using precise garbage collection (previously it was based on Mono's built-in GC, which is conservative). Fixes strange corner cases with the old system, where in the worst case it could reload prefabs from disk during unloading.
· Shaders: Added SubShader tag "ForceNoShadowCasting". When this tag is present, no shadows will be cast from this object, even if shader has a shadow caster pass somewhere.
· Shaders: Sampler precision support for mobile, you can use sampler2D_half, sampler2D_float, samplerCUBE_half, samplerCUBE_float types which will translate into mediump & highp samplers for GLES2.0.
· Shaders: Shaders will now use the shadow caster pass of the selected subshader if a shadow pass exists. If no shadow pass exists it will fallback to the default shadow pass.
· Substance: decrease the memory overhead of Substance instances created at runtime.
· Substance: If present, the more user friendly input "labels" are displayed in the Inspector instead of the input "names".
· Substance: Input groups and HSL adjustments are now presented as foldouts in the Inspector.
· Substance: Less code is embedded in the various Unity players.
· Substance: lower memory consumption when dealing with multi-graph Substances.
· Substance: New "Use caching" load behavior for Substances (textures are written to disk/flash after being generated and are reloaded from there at subsequent app/game launches).
· Substance: On mobile platforms "Compressed" Substance textures are now compressed at runtime to DXT or PVRTC if supported by the GPU.
· Substance: Procedural textures can now be read in the runtime API (ProceduralTexture.GetPixels32). Substances must be set to RAW and have the isReadable property set for GetPixels32 to work.
· Substance: Updated Substance engines for all platforms (faster rendering, better threading, lower memory consumption).
· Substance: XML presets can now be read from / applied to substances in the runtime API.

Changes:
· Audio: AudioSource.Play(offset) is now considered deprecated. It will still work as before, but will output a warning. Instead, users are encouraged to use AudioSource.PlayDelayed(delay) which takes a delay parameter in seconds instead of a sample count in the arbitrarily chosen 44100 reference rate that was used previously.
· DestroyImmediate is no longer allowed to be called from within animation events.
· Editor: Removed buttons in Console window for Open Editor Log and Open Player Log (on OS X) and put them into the custom menu for the Console instead (accessed through the upper right corner of the window).
· iOS: Changed how VRAM amount is estimated and reported, now it is 1/4 of total physical memory.
· iOS: Keyboard handling extracted to trampoline.
· Mecanim: Avatar body and skeleton mask has been merged into AvatarMask to simplify the workflow. Any created object of type AvatarBodyMask or AvatarSkeletonMask should be converted to AvatarMask. Any AvatarSkeletonMask set into a layer mask would be lost, you need to manually re assign the mask.
· Mecanim: CycleOffset is set automatically to 0.5 for clips that are being mirrored in States/BlendTrees.
· Mecanim: In model importer animation tab for humanoid clip, the option Keep Additionnal bone has been removed since you can now choose wanted transform in the Avatar mask.
· Static batching no longer supports generating triangle strips.
· UnityEngine.dll and mscorlib.dll are no longer accepted as assets.

What's new in Unity 4.0 Beta 7:

August 23rd, 2012

New Humanoid Animation System:
· Once imported as muscle clips, animations can be used with all humanoid characters with no additional conversions needed.
· Use the same animations on different proportion characters with no overhead or need for storing multiple versions of the clip.
· Map the bones of your model to human muscles with a single click, or fine tune the setup for full control.
· Slice up your authored or motion-captured animations directly inside Unity with the industry's best tool for the job.
· Preview the animation as your drag the ranges of a clip.
· Indicators for pose looping quality and motion looping quality lets you easily pick the range with optimal looping.
· Differences between start and end pose is smoothed out by the importer to ensure perfect looping.
· Support for non-humanoid characters will be added in next pre-order beta build.

DirectX 11 Rendering:
· On Windows Vista and later, and with DX10 or better level GPU, you can use DirectX 11 now.
· Player Settings has "Use DX11" option; when it it set the player will try using DX11.
· Editor can be switched to DX11 in Preferences. This is confusing; we'll fix it in a later build.
New features:
· Geometry shaders (require DX10 GPU) and hull/domain shaders (require DX11 GPU). #pragma geometry, hull, domain in shader files.
· Compute shaders (*.compute files, ComputeShader in scripts)
· ComputeBuffer scripting API ("structured buffers" in DX11 lingo). Can use them in compute shaders and regular shader model 5.0 shaders (Material.SetBuffer, Shader.SetGlobalBuffer).
· "random write" RenderTextures ("UAVs" in DX11 lingo). Graphics.SetRandomWriteTarget, RenderTexture.enableRandomWrite.
· Graphics.DrawProcedural & DrawProceduralIndirect.
· DX11-specific RenderTexture formats: RenderTextureFormat.R8, ARGBInt, RGInt, RInt.
· 3D RenderTextures (RenderTexture.isVolume, volumeDepth). Fill them as "random write" textures from a compute or pixel shader.
· In shaders, can optionally use CBUFFER_START(name) .. CBUFFER_END macros to markup separate constant buffers.

Linux Publishing:
· Export a standalone player for 32-bit (x86) or 64-bit (amd64) Linux.
· Select "Linux 32-bit" or "Linux 64-bit" from the Target Platform list in the Build Settings.
· When building a player for Linux on Windows, you will first need to make the binary executable before being able to run it on Linux. Do this by running 'chmod +x' on the executable or right clicking and selecting "Allow to run as application".
· Supported Platforms
· Standalone players will run on most modern Linux systems with vendor-supplied graphics drivers.
· Official support will be provided for 32 or 64-bit Ubuntu Linux, version 10.10 (Maverick Meerkat) or newer, with graphics cards using vendor-supplied drivers.

Graphics Features:
· Terrain: Normal map & custom shader support for Terrain. Added built-in shader Nature/Terrain/Bumped Specular; added "normal map" texture slot to terrain splat maps; added Material field under terrain settings.
· 3D (volume) textures support. Currently no way to import them, but you can create them from script (Texture3D) and use them in shaders (sampler3D and tex3D). Also SystemInfo.supports3DTextures.
· Shadows on mobile devices! Only directional lights, no shadow cascades, no soft shadows.
· Requires GL_OES_depth_texture extension. Most notably, Tegra-based devices do not support it.
· 3D (volume) textures support. Currently no way to import them, but you can create them from script (Texture3D) and use them in shaders (sampler3D and tex3D). Also SystemInfo.supports3DTextures.
Fonts:
· Dynamic font rendering on all platforms (including mobiles) with identical results (via FreeType).
· Simple html-style text markup support to have multiple font sizes, styles and colors in a string in UnityGUI, GUIText & TextMesh.
Cubemaps:
· New Generate Cubemap texture import option that creates a cubemap from vertical/horizontal cross or row/column of images.
· Seamless cubemap option that makes sure edges of faces match up.
· Cubemap assets reference their original textures in the editor instead of copying their pixels at assign time.
· Scripting API: Cubemap.SmoothEdges.
· Lightmapping: "Bake selected" no longer destroys lightmaps on objects that aren't selected. Instead it updates lightmaps on selected objects, as expected.
· Lightmapping: Normalmaps are taken into account when lightmapping, which allows to add detail to lightmaps and makes the transition between near and far distance in Dual Lightmaps mode less visible.
· Render Textures: added RenderTextureFormat.ARGBFloat, RGFloat, RGHalf, RFloat, RHalf formats.
· Meshes can have a non-triangle topology now. You can create meshes that are lines, points or quads from scripts. See MeshTopology enum, Mesh.GetIndices, SetIndices, GetTopology.
· Added SkinnedMeshRenderer.BakeMesh to "bake" skinned mesh result into a regular mesh.
Shuriken particle system:
· Automatic simulation culling support. Particle systems will only update when visible. When it is not possible to support this automatically, Shuriken shows why directly inside the UI.
· External forces support - use Wind Zones with particles.
· Bent normals support for sprites.
· Support for sorting and rendering with immediate children (solving sorting issues for combined systems).
Shaders:
· Added built-in matrix variables, UNITY_MATRIX_V (view matrix), UNITY_MATRIX_VP (view*projection).
· Added float4 unity_DeltaTime, contains (dt, 1/dt, smoothdt, 1/smoothdt).
Shader helper macros added:
· UNITY_DECLARE_SHADOWMAP(tex), UNITY_SAMPLE_SHADOW(tex,uv), UNITY_SAMPLE_SHADOW_PROJ(tex,uv).
· UNITY_NEAR_CLIP_VALUE, defined to 0.0 on D3D-like, -1.0 on GL-like platforms.
· UNITY_COMPILER_HLSL (d3d11, 360), UNITY_COMPILER_HLSL2GLSL (gles), UNITY_COMPILER_CG if you need to determine which shader compiler is used on a platform.
· UNITY_INITIALIZE_OUTPUT(type,name) to help with DX11 shader compiler requiring full initialization of "out" parameters.
· OpenGL ES 2.0: Supports depth textures on Android.
· Scripting API: added Texture.SetGlobalAnisotropicFilteringLimits.

New Project Browser (replaces the Project Window):
· View assets by preview icons.
· Seperate tree for folders for better overview of folder structure.
· Search for assets using droplists for type and asset labels.
· Save searches to favorites list for easy access to most used searches.
· Drag folders to favorites list for easy access to most used folders.
· Enable searching the Asset Store and previewing assets.
· You can switch Project Browser to old-style one column layout in the context menu of the window (upper right corner).

Rewrite of the GUI system:
The existing GUI system (OnGUI) had its core rewritten, optimized and cleaned up. It uses less memory and induces less garbage collection cycles. Un-scientific performance increases measured at:
· iOS, with GUILayout ~2.5x faster.
· Mac, with GUILayout ~3x faster.
· iOS, no GUILayout ~10x faster.
· Mac, no GUILayout ~20x faster.
· Uses less memory and induces less garbage collection cycles.
· Note: this is not the “New GUI” that is coming to a later Unity 4.x release. It’s existing GUI, made much faster.

Other Features:
· Added a new development console to show error messages on screen in development builds.
· Android: Added Eclipse project generation.
· Android: Support for APK Expansion Files (OBBs) - effectively enabling applications larger than 50Mb in the Google Play Store.
· iOS: Target Resolution Player Setting was redesigned to better suite development workflow on multiple iOS devices. Two new “Auto (Best performance)” and “Auto (Best Quality)” settings allow Unity Runtime to choose most optimal rendering resolution according to device GPU capabilities.
· Debugger: Webplayers can now be attached to and debugged just like standalones.
· Editor: Add components and scripts to Game Objects easier and faster through the new Add Component drop-down directly inside the Inspector.
· Editor: Create your own Inspector GUI for custom classes or attributes and see it used across all scripts that use those classes or attributes.
· Fonts: Custom fonts can now use arbitrary character rectangles instead of a fixed grid.
· Fonts: Font character placement properties are now accessible from scripting.
· Fonts: Imported fonts can now be converted to editable custom fonts from the gear menu.
· Gradient (known from the Shuriken editor) is now exposed to scripts: Gradient, GradientColorKey, GradientAlphaKey.
· Navigation: NavMeshAgent supports prioritized levels of avoidance.
· Navigation: NavMeshObstacle component added.

Upgrade guide:
· We have changed how the active state of GameObjects is handled. GameObjects active state will now affect child GameObjects, so setting a GameObject to inactive will now turn the entire sub-hierarchy inactive. This may change the behavior of your projects. GameObject.active and GameObject.SetActiveRecursively() have been deprecated. Instead, you should now use the GameObject.activeSelf and GameObject.activeInHierarchy getters and the GameObject.SetActive() method.
· Editor: We have reset the preferences from 3.x to 4.x. This affects your saved window layouts, the project wizard list, saved filters etc.
· Editor: While an asset is being imported it will not be persistent. E.g. if you postprocess a texture and query its asset path, it will return an empty string. Assets outside of the asset postprocessor can, of course, be accessed at any point.
· iOS: Target Resolution Player Setting was redesigned to better suite development workflow on multiple iOS devices. Two new “Auto (Best performance)” and “Auto (Best Quality)” settings allow Unity Runtime to choose most optimal rendering resolution according to device GPU capabilities. Some custom editor scripts might need to be updated to comply with these changes. Rendering resolution might be also changed from game scripts using Screen.SetResolution API.
· iOS: Device SDK Player Settings was simplified and now contains only two entries “Device SDK” and “Simulator SDK”. Corresponding editor API entries were also changed and some custom editor scripts might need to be changed.
iOS: Unity 4.0 discontinues support for ARMv6 devices (iPhone 1st gen, iPhone 3G, iPod Touch 1st/2nd gen). This affects existing project development in several ways:
· Target Platform Player Setting was removed from Unity Editor. Now all Unity iOS applications are ARMv7-only. Corresponding PlayerSetting.iOS Editor API entries also were removed. You might need to fix some of your editor scripts for that.
· Graphics API level (Open GL ES 1.1 or 2.x) selection was moved to separate Graphics Level Player Setting. This setting is synced with the Android platform.
· Applications that were already released to the App Store as supporting ARMv6+ARMv7 or ARMv6-only now can be updated only if Target iOS Version Player Setting is set to “4.3” or higher.
· Mobile: Unity 4.0 brings hard shadow support to mobiles. Shadows for mobiles are enabled at the default Quality Setting. And if the project is shared with desktop platforms then shadows might just appear on mobiles too when project gets imported into Unity 4.0. Some manual tweaking of lighting/shadow setup might be required for optimal performance on mobiles.
Mobile: We changed the way Texture2D.ReadPixels works. Now, if you do call it during Update (or, generally, not during rendering frame) to grab the copy of the screen, the call will be deferred to the end of the current frame. Due to this, logic behind Apply was changed too. What you need to do if you use ReadPixels to read pixels from the screen:
· if you just grab screen copy and call Apply, both calls will be deferred to the end of the frame
· if you grab screen copy, and do something with it, and call Apply after that: you need to defer all this to the next frame. The easiest way is to use coroutines with yield in between ReadPixels and your operations plus Apply.
· On the other hand, you can always do ReadPixels in Camera's OnPostRender, or when you have active RenderTexture.
· Runtime: GameObjects marked DontDestroyOnLoad are no longer temporarily deactivate when loading a level. They will also not receive an OnDisable / OnEnable call when loading a level.

Profiler Improvements:
· Android: Profiler blocks marked up in rendering commands via EXT_debug_marker (for tools like PerfHud).
· GPU profiling support for Tegra-based Android devices.
· GPU profiler detailed objects view sorts in decreasing GPU time.
· Optimized memory usage and UI performance for complex profiles.
· Scripting API: Profiler.GetMonoHeapSize, GetMonoUsedSize.
· Made profiler player connection run threaded to improve throughput and reduce lack of profile data.

Asset Pipeline Improvements:
· Added userData string property to AssetImporter, use this to pass per asset data to asset post processor.
· Manual asset reimport (via context menu) always reimports, even if cache server already has the result.
· Optimized filesystem performance of asset imports. Library/cache and Library/previews folders are gone; all imported results are in Library/metadata.
· Keep Quads added to mesh importer, most interesting with DX11 tessellation shaders.

Other Improvements:
· Android: Exposed control over SYSTEM_UI_FLAG_LOW_PROFILE ("lights-out" mode) through Screen.fullScreen.
· Animation : Can now preview non-Mecanim animation in previewer.
· Cache Server: Now includes a 32-bit linux build.

The label below the gizmo now toggles between perspective and ortho as well. Shift-clicking or middle-mouse clicking the center cube will set the "nice" perspective view and shift-clicking or middle-mouse clicking the cones will enforce ortho.
· Editor: Simplified mobile graphics emulation; only have OpenGL ES 1.1 & 2.0 now.
· Editor: Lightmaps now get "best" compression quality for mobiles when available.

What's new in Unity 3.5.0:

February 15th, 2012

Major New Features:
· Adobe Flash: Final version of 3.5 supports a preview of publishing to Adobe SWF format, otherwise known as Flash Export.
· A separate FAQ for this release is available at http://unity3d.com/unity/publishing/flash.
· New Particle System - "Shuriken".
· Edit, view and playback control in Edit Mode. You can manually scrub time to inspect and fine-tune the particle system using the Scene View playback controls.
· Module-based: Each particle system has several modules that can be enabled to control color, size and movement of particles.
· Groupable: It is possible to group / compose several particle systems in a hierarchy and their playback will behave as one particle system.
· Built-in curve editor for easy curve editing.
· Pathfinding and avoidance sub-system added.
· NavMesh: Path-finding API. Bake navigation mesh with markup areas.
· NavMeshAgent: Character navigation. Avoidance system.
· OffmeshLink: used to create arbitrary connections between NavMesh polygons.
· Built-in LOD management via LOD Groups.
· Lightmap baking works for LODed models. The lightmapped objects use a surface transfer algorithm similar to normal map baking.
· Asset Cache server.
· Assets imports are shared between project folders and users. Switching Platform takes minutes instead of hours on large scale projects. Grabbing changes from other team members is almost instant.
· Built-in HDR support and adaptive tonemapping.
· The 3.5 image effects package comes with adaptive tonemapping, bloom and depth of field image effects that are optimized for HDR.
· Multithreaded rendering.
· Most of rendering & driver overhead is put onto another CPU core on multicore systems.
· You don't have to do anything, it just works!
· Currently only on PC / Mac / Xbox 360; and not in the web player yet.
· Light Probes, which allow for using baked lighting on characters and other dynamic objects.
· Directional Lightmaps.
· Generic external version control (.meta files) is now available in the free version.
· Google Native Client is now supported
· It is now possible to select and edit multiple objects simultaneously with the Inspector!
· The Inspector preview supports showing the multiple selected objects.
· Multi-editing can be enabled for custom editors with a single line of code if they are based on using SerializedProperty.
· Occlusion Culling has been rewritten from scratch, it is much faster to compute and always correct
· OcclusionPortal component has been added to allow doors that can be opened and closed at runtime.
· Terrains work well with occlusion culling now.
· The default mode for occlusion culling is “automatic portal generation”, which is very accurate and works well for dynamic objects.
· Introduced the “Occludee Static” flag. This is used to mark objects as statically occludable without making them occluders. For example transparent objects that don't move should be marked as Occludee Static.
· Text-based scene and prefab format can be used for improving team workflows. This can be turned on or off in the Editor Settings for each project.
· GPU Profiler: added the ability to see GPU usage to the profiler.
· A ton of memory and performance optimizations. Several improvements to multithreading.

Graphics Features:
· SkinnedMeshRenderer bounding volume is now always relative to the most common root bone and works much better with Ragdolls.
· UpdateWhenOffscreen bounding volume option now uses bone-relative bounding volumes instead of vertices and is around 100x faster.
· WebCamTexture class now supports cameras.
· High-resolution screenshots can now be done via Application.CaptureScreenshot’s superSize parameter.
· Added new Soft Shadows mode for Directional Lights that uses rotated disk sampling pattern.
· Lightmapping: Added the “Area Light” light type (baked only).
· Lightmapping: Skinned meshes can now be lightmapped. Use this for meshes that don't change the pose much after baking.
Advanced rendering controls:
· Image Effects can optionally be applied before any transparent geometries are drawn. Use ImageEffectOpaque attribute on the OnRenderImage function.
· Subtractive/Min/Max blending support, use BlendOp Min|Max|Sub|RevSub in ShaderLab.
· Multiple Render Targets, Graphics.SetRenderTarget can take multiple color targets.
· Enabled sharing of depth buffers between different color buffer targets, see Graphics.SetRenderTarget, RenderTexture.colorBuffer, etc.
Various graphics optimizations:
· Optimizations for OpenGL ES 2.0 to avoid performance spikes with dynamic geometry.
· Optimized culling and shadow caster culling.
More low level rendering possibilities from native code Plugins:
· Ability to access Direct3D 9 device pointer.
· Plugin callbacks on the rendering thread, so that low-level plugin rendering can co-exist with multithreaded renderer in Unity 3.5.
· Surface Shaders: added optional final color modifier function (finalcolor directive). This can be used to implement custom Fog on platforms that can't do usual fog (like Xbox 360 or PS3).
· Added renderer.SetMaterialBlock for a lightweight way of adding per-instance material parameters without duplicating the materials. Also, the MaterialPropertyBlock does not have fixed small capacity any longer.
Quality settings overhaul:
· Quality settings can now be enabled / disabled per platform. Quality levels that are disabled on a target platform will be stripped on build.
· Maximum LOD level and LOD bias can be setup in the Quality settings.
· The smallest LOD level in the quality settings will be used to automatically strip higher LOD levels. This makes it possible to strip any high poly models and all their dependencies on low-end devices.
· Editor Features
· Middle-click on any surface in the Scene View to focus on the clicked point.
· AssetModificationProcessor class created with custom VCS systems in mind.
· Adds IsOpenForEdit check on assets which can prevent assets from being edited.
· The preview in the Inspector can be detached to a separate window.
· Implemented support for C4D file import from Cinema4D R13.
· Implemented better detection of imported material types. Unity uses normal-map and transparency properties (texture or factor) to apply one of the following shaders: "Bumped Diffuse", "Transparent/Diffuse" or "Transparent/Bumped Diffuse".
· Implemented import of texture Tiling and Offset values.
· Implemented support for baking animation through FBX exporter during C4D file import (supported only from Cinema 4D R13, the old version uses our native IK baker).
· Mac: Added support for full-screen mode in the new Mac OS X Lion 10.7.
· Improved preferences window that users can extend by using the PreferenceItem attribute.
· Gizmos can have world-space sizes. Nice, hi-res gizmos were added.
· The Transform gizmo has a new planar transform tool for performing two-axis translations, which replaces the Free Transform tool. Hold the 'shift' key to switch back to the Free Transform tool.
· GUI class now has a DrawTextureWithTexCoords function for specifying texture coordinates.
· Entire curves can now be dragged vertically.
· Gizmos are now depth-tested, and exist in world space. The gizmo size can be adjusted using the existing gizmos size slider.
· Introduced a more advanced Static checkbox: It is now possible to mark objects static for different situations (lightmapping, navigation, occlusion etc).
· Made it possible to find objects in scene that reference the selected asset.
· Texture Importer for pvrtc-enabled platforms allows to select compression quality.
· New Prefab system allows adding / removing components from instances without breaking the prefab connection.
· Backwards compatibility with old prefabs is maintained.
· Made sure prefabs do not show up as “missing” in play mode.

Audio Features:
· Enabled audio buffer read and write access via AudioClip::Get/SetData
· Introduced low latency custom filters. Filter/Produce audio at mixer rate with OnAudioFilterRead() callback.

· Made mixer settings accessible from script (buffer sizes and sample rate).

iOS Features:
· Implemented Build&Run support for Xcode 4.x. (Not compatible with Xcode 3.x, but can be turned off in Editor settings).
· Accelerometer frequency now is controlled from Player Settings.
· Application.targetFrameRate works. Removed kFPS constant due to this. 30 FPS is default.

· Added iAd support.
· Added push notification support.
· Added Compass and Gyroscope support.
· Added Camera support.
· Added Microphone support.
· Image Filters now determine the format for intermediate Render Targets from currently bound FrameBuffer (most usual - default Display Buffer). So if you use a 16bit Display Buffer you will get 16bit rt (RGB565). While this makes image filters a bit faster, it also is more GLES-conformant. If you want to use Image Filters that needs alpha channel or see banding, please set "Use 32-bit Display Buffer" checkbox in Player Settings, or use newly added Handheld.use32bitDisplayBuffer API.

Android Features:
· Added "Show Loading Indicator" option, to show spinner when loading level synchronously.
· QualitySettings.antiAliasing now works, allowing you to set AA level at runtime or in Editor.
· Added "Use 32-bit Display Buffer" and "Use 24-bit Depth Buffer" options.
· Added the API “Screen.dpi” to help determine the need for high/low resolution graphics.
· Added Joystick / Mouse (USB) support - only available with Honeycomb 3.1 and later.

· Added Camera support
· Added Microphone support.
· Added Texture Override for ETC/RGBA16, under Build Settings.
· Added API targets for Honeycomb 3.2 (MR2) and Ice Cream Sandwich (4.0)

· Other Features
· Upgraded to MonoDevelop 2.8.2.
· Generic Social API added, which supports GameCenter only at the moment and Xbox Live support will be enabled later. Limited dummy functionality runs on unsupported platforms (so code is testable in the Editor for example). Third parties can implement the interface to add support for their implementation on any platform.
· Physics: Added ConfigurableJoint.swapBodies property to make the joint act as if the two connected Rigidbodies were swapped.
· AssetPostProcessor can now be versioned. See AssetPostProcessor.GetVersion for details.
· Asset Server can now be used with Cache Server. Note that this requires committing all assets to the server project after upgrading to 3.5 and that the server project will not be usable by older Unity versions after that commit. So remember to back up everything, including the server project.
· Added Application.StreamingAssetPath which points to the location of the data in the Assets/StreamingAssets folder on all build targets.
· IME: Added Input.isIMESelected to determine if the user has currently enabled IME conversion mode for keyboard input.
· All Editor Settings files that need to be versioned have been moved into a ProjectSettings folder.
· If upgrading an existing project the current settings files will be copied to the new folder.
· If you are using version control you should upgrade your project by opening it in the editor and then you should remove the old settings files from version control and simply add the ProjectSettings folder.
· Conclusion: All you need to add to version control in 3.5 is your Assets folder and ProjectSettings folder.

Improvements:
Android:

· Fixed formatting issues for code snippets on IE
· Fixed up many code examples.

Editor:
· Fixed the "Generate Lightmap UVs" reducing the difference between mac/win. Not there yet, but should be fixed for the most part. Please reimport meshes and rebake lightmaps.
· A LOD group that was created on import can now be updated in the scene and send these settings back to the importer.
· Added "All" and "None" items for active Layer selection menu.
· API: Added optional parameter includeChildren to PropertyField to allow creating entire class or array controls with a single function call.
· API: Exposed GetIconSize and SetIconSize.

· Upgraded FBX SDK to 2012.2.
· When changing numbers using sliders, do context sensitive rounding. The rounding will leave exactly enough decimals to represent the change resulting from moving the slider one pixel. If more decimals are typed in manually, they will not be lost (within the limitations of floating point numbers).
· When selecting objects of different types, the Inspector will now help narrowing down the selection to objects of only one type.
· You can now set a default font color via the font importer.

Graphics:
· Extended the maximum number of shader keywords from 32 to 64.
· For each shader compilation error show the keywords that were used.
· MaterialPropertyBlock can now have an unlimited number of properties.
· OnWillRenderObject lets you rotate or slightly move an object before rendering. The updated transform will be used during the render pass. This makes it possible to for example align a billboard only when it is visible using OnWillRenderObject.

Lightmapping:
· Exposed the padding property that controls texel spacing between bake instances.
· Improved mipmap generation for lightmaps - the space between bake instances is filled with colors coming from those bake instances when going down and up the mip chain. The lighting in smaller mip levels is more accurate and preserves the overall feel of the lightmap better. Please rebake the lightmaps to get the benefit.
· Made fetching lightmaps use much less temporary memory.

iOS:
· Added Caching.SetNoBackupFlag and Caching.ResetNoBackupFlag to set "No Backup" flag on cache.
· Added iPhone.SetNoBackupFlag and iPhone.ResetNoBackupFlag to set "No Backup" flag.

· Support copying files from Assets/StreamingAssets for Win/Mac standalone players.
· Unwrap: All known cases of mac/win uv generation were fixed. Please reimport your meshes.
· Web Player: If the embedding page or unity3d file is hosted on https, the web player will use https for all connections (update checks and downloads), so the browser will not show warnings about insecure connections.
· When baking occlusion culling with transparent objects marked as occluders a warning is now given telling you which objects are marked static incorrectly.
· When imported assets are dirtied because a script modifies the imported asset it will no longer cause the asset to be reimported. Instead it will unload the asset and reload from disk as soon as nothing is referencing the asset anymore. This fixes an issue where a lot of assets would get reimported when shutting down Unity after entering playmode depending on what the scripts did.
· Windows: Connected joysticks are detected at runtime.

What's new in Unity 3.5.0 Beta 6:

December 28th, 2011

Major New Features:
· Adobe Flash: This Public Preview version of 3.5 support publishing to Adobe SWF format, otherwise known as Flash Export: A separate FAQ for this preview release is available at http://unity3d.com/preview/faq.

· Built-in LOD management via LOD Groups.
· Lightmap baking works for LODed models. The lightmapped objects uses a surface transfer algorithm similar to normal map baking.
· Built-in HDR support and adaptive tonemapping.

New Particle System - "Shuriken":
· Edit, view and playback control in Edit Mode. You can manually scrub time to inspect and fine tune the particle system using the Scene View playback controls.
· Module based: Each particle system has several modules that can be enabled to control color, size and movement of particles.
· Compose several particle systems in a hierarchy and playback of them will behave as one particle system.
· Built-in curve editor for easy curve editting.

Pathfinding and avoidance sub-system added:
· NavMesh: Path-finding API. Bake navigation mesh with markup areas.
· NavMeshAgent: Character navigation. Avoidance system.

Occlusion Culling has been rewritten from scratch, it is much faster to compute and never incorrect:
· OcclusionPortal component has been added to allow for doors that can be opened and closed at runtime.
· Terrains works well with occlusion culling now.
· Default mode for occlusion culling is automatic portal generation, which is very accurate and works very well for dynamic objects.
· Support for Occludee Static. This is used to mark objects as statically occludablable but not be an occluder. For example transparent objects that don't move should be marked as Occludee Static.

Asset Cache server:
· Assets imports are shared between project folders and users. Switching Platform takes minutes instead of hours on large scale projects. Grabbing changes from other team members is almost instant.

Gamma-correct rendering option:
· Multithreaded rendering.
· Most of rendering & driver overhead is put onto another CPU core on multicore systems.
· You don't have to do anything, it just works!
· Currently only on desktops & Xbox 360; and not in the web player yet.
· Unity for Google Native Client.
· Light Probes, which allow for using baked lighting on characters and other dynamic objects.
· Directional Lightmaps support.
· It is now possible to select and edit multiple objects simultaneously with the Inspector!
· The Inspector preview supports showing the multiple selected objects.
· Multi-editing can be enabled for custom editors with a single line of code if they are based on using SerializedProperty.
· Text based scene and prefab format can be used for improving team workflows. This can be turned on or off per project in the Editor settings.
· GPU Profiler. Added the ability to see GPU usage to the profiler.
· A ton of memory and performance optimizations. Several improvements to multithreading.

Graphics Features:
· SkinnedMeshRenderer bounding volume is now always relative to the most common root bone and works much better with Ragdolls: UpdateWhenOffscreen bounding volume option now uses bone relative bounding volumes instead of vertices and is around 100x faster.
· WebCamTexture class to support cameras!
· High-resolution screenshots can be done via Application.CaptureScreenshot superSize parameter.
· Added new Soft Shadows mode for Directional Lights that uses rotated disk sampling pattern.
· Lightmapping: Added the Area Light (baked only) light type.
· Lightmapping: Skinned meshes can now be lightmapped. Use for meshes that don't change the pose much after baking.

Advanced rendering controls:
· Image Effects can optionally be applied before any transparent geometries are drawn. Use ImageEffectOpaque attribute on the OnRenderImage function.
· Subtractive/Min/Max blending support, use BlendOp Min|Max|Sub|RevSub in ShaderLab.
· Multiple Render Targets, Graphics.SetRenderTarget can take multiple color targets.
· Ability to share depth buffers between different color buffer targets, see Graphics.SetRenderTarget, RenderTexture.colorBuffer etc.

Various graphics optimizations:
· Optimizations for OpenGL ES 2.0 to avoid performance spikes with dynamic geometry.
· Optimized culling and shadow caster culling.

More low level rendering possibilities from native code Plugins:
· Ability to access Direct3D 9 device pointer.
· Plugin callbacks on the rendering thread, so that low-level plugin rendering can co-exist with multithreaded renderer in Unity 3.5.
· Surface Shaders: added optional final color modifier function (finalcolor directive). This can be used to implement custom Fog on platforms that can't do usual fog (like Xbox 360 or PS3).
· Added renderer.SetMaterialBlock for lightweight way of adding per-instance material parameters without duplicating the materials. Also, MaterialPropertyBlock does not have fixed small capacity anymore.

Quality settings overhaul:
· Quality settings can now be enabled / disabled per platform. Quality levels that are disabled on a target platform will be stripped on build.
· Maximum LOD level and LOD bias can be setup in the Quality settings
· The smallest LOD level in the quality settings will be used to automatically strip higher LOD levels. This makes it possible to strip any high poly models and all their dependencies on low-end devices.

Editor Features:
· Middle-click on any surface in the Scene View to focus on the clicked point.
· AssetModificationProcessor class API created with custom VCS systems in mind: adds IsOpenForEdit checks on assets which can prevent assets from being edited.

· The preview in the Inspector can be detached to a separate window.
· Implemented support for C4D file import from Cinema4D R13.
· Implemented better detection of imported material types. Unity uses normal-map and transparency properties (texture or factor) to apply one of the shaders: "Bumped Diffuse", "Transparent/Diffuse" or "Transparent/Bumped Diffuse".
· Implemented import of texture Tiling and Offset values.
· Implemented support for baking animation through FBX exporter during C4D file import (supported only from Cinema 4D R13, old version use our native IK baker).
· Mac: Added support for full-screen mode in the new Mac OS X Lion 10.7.
· Improved preferences window that users can extend using the PreferenceItem attribute.
· Gizmos can have world-space sizes. Nice, hi-res gizmos were added.
· The Transform gizmo has a new planar transform tool for performing two-axis translations, which replaces the Free Transform tool. Hold the 'shift' key to switch back to the Free Transform tool.
· GUI class now has a DrawTextureWithTexCoords function for specifying texture coordinates.
· Entire curves can now be dragged vertically.
· Gizmos are now depth tested, and exist in world space. The gizmo size can be adjusted using the existing gizmos size slider.
· It is now possible to mark objects static for different situations (lightmapping, navigation, occlusion ect) via the improved static checkbox.
· Find objects in scene that reference the selected asset.
· Small appearance tweaks
· New Prefab system allows for adding / removing components from instances without breaking the prefab connection.
· Backwards compatiblity of old prefabs is maintained
· Made prefabs not show as Missing in play mode

Audio Features:
· Audio buffer read and write access (AudioClip::Get/SetData)
· Low latency custom filters. Filter/Produce audio at mixer rate with OnAudioFilterRead() callback.
· Extended inspector GUI support for custom filters (out gain and performance meters).
· Microphone support on all platforms
· Mixer settings accesible from script (buffer sizes and samplerate)

iOS Features:
· Implemented Build&Run support for Xcode 4.x. (Not compatible with Xcode 3.x, but might be turned off in Editor settings).
· Accelerometer frequency now is controlled from Player Settings.
· Application.targetFrameRate works. Removed kFPS constant due to this. 30 FPS is default
· Added "Show Loading Indicator" option, to show spinner when loading game.
· GameCenter support added through the social API (does not include matchmaking and voice features atm).
· iAd support added.
· Push notification support added.
· Compass support added.
· Camera support added.
· Microphone support added.
· Image Filters now determine the format for intermediate Render Targets from currently bound FrameBuffer (most usual - default Display Buffer). So if you use 16bit Display Buffer you will get 16bit rt (RGB565). While it makes image filters a bit faster it also is more gles-conformant. If you want to use Image Filters that needs alpha channel or see banding, please set "Use 32-bit Display Buffer" checkbox in Player Settings, or use newly added Handheld.use32bitDisplayBuffer API.

Android Features:
· Added "Show Loading Indicator" option, to show spinner when loading level synchronously.
· QualitySettings.antiAliasing now works, allowing you to set AA level at runtime or in Editor.
· Added "Use 32-bit Display Buffer" and "Use 24-bit Depth Buffer" options.
· Added Screen.dpi to help determine the need for high/low resolution graphics.
· Added Joystick / Mouse (USB) support - only available with Honeycomb 3.1 and later.
· Improved load times with a new file reader backend.
· Profiler information can now be tunneled over ADB.
· Input latency is improved, with input events handled in native code with Gingerbread 2.3 and later.
· Support for Gyroscope / Compass input added.
· Camera support added.
· Microphone support added.
· Added Texture Override for ETC/RGBA16, under Build Settings.
· Added API targets for Honeycomb 3.2 (MR2) and Ice Cream Sandwich (4.0)

Other Features:
· MonoDevelop: Upgraded to MonoDevelop 2.8.2.
· Generic Social API added, it supports GameCenter only at the moment and Xbox Live support will be enabled later. Limited dummy functionality runs on unsupported platforms (so code is testable in the Editor for example). Third parties can implement the interface to add support for their implementation on any platform.
· Physics: Added ConfigurableJoint.swapBodies property to make the joint act as if the two connected Rigidbodies were swapped.
· AssetPostProcessor can now be versioned. See AssetPostProcessor.GetVersion for details.
· Asset Server can now be used with Cache Server. Note that this requires committing all assets to the server project after upgrading to 3.5 beta 4 and that the server project will not be usable by older Unity versions after that commit. So remember to back up everything, including the server project.
· Added Application.StreamingAssetPath which points to the location of the data in the Assets/StreamingAssets folder on all build targets.
· Added Input.isIMESelected to determine if the user has currently enabled IME conversion mode for keyboard input.
· All Editor settings files that needs to be versioned has been moved into a ProjectSettings folder.
· If upgrading an existing project the current settings files will be copied to the new folder.
· If you are using version control you should upgrade your project by opening it in the editor and then your should remove the old settings files from version control and simply add the ProjectSettings folder.
· Conclusion: All you need to add to version control from 3.5 beta3 is your Assets folder and ProjectSettings folder.

Improvements:
· All Project Settings are now in a folder called "ProjectSettings" next to the assets folder. This folder should be added to version control. This means that all assets in the library should be only controlled by Unity and never be under version control.

· When baking occlusion culling with transparent objects marked as occluders a warning is now given telling you which objects are marked static incorrectly.
· When imported assets are dirtied because a script modifies the imported asset it will no longer cause the asset to be reimported. Instead it will unload the asset and reloadk from disk as soon as nothing is referencing the asset anymore. This fixes an issue where a lot of assets would get reimported when shutting down Unity after entering playmode depending on what the scripts did.

What's new in Unity 3.4.2:

November 3rd, 2011

Editor:
· Fixed crash when editing audio source.
Android:
· Fixed corrupted splash image on Icecream-Sandwich.
· Allow audio playback only when application is focused (prevents audio on the unlock screen).
· Made sure the on-device-profiler only uses active network interfaces.
· Fixed an issue where mscorlib.dll could not be found.

iOS:
· Fixed random crashes when building with Xcode 4.2 (iOS SDK 5.0).
· Fixed crash with auto-rotation on iOS 5.
· Disabled workaround for ipad2 driver bug with msaa+colormask+blend when running on iOS 5 (was fixed by Apple).
· Made Cache Path for AssetBundles be compatible with new Apple Guidelines: /Library/Caches instead of /Documents.

Monodevelop:
· Fixed compilation issues of Javascript.

What's new in Unity 3.4.0:

July 27th, 2011

Features:
Allegorithmic Substance Integration:
· Native support for Allegorithmic procedural Substance materials.
· Tweak and change exposed substance parameters right inside of Unity.
· Change substance parameters at runtime on PC and Mac.
· Gain major file size savings due to the compactness of procedural textures on PC and Mac.
· Bake substances into regular textures and materials on mobile platforms.
Gizmo and Icon Management:
· Scene View icons for game objects and script assets can now easily be assigned by using the new Icon Selector opened by clicking on the icon in the Inspector.
· Rendering of gizmos and icons can now be controlled using the new 'Gizmos' drop-down window found in the toolbar of the Scene View and the Game View.
· Toggling of gizmos is linked to the collapsed or expanded state of the corresponding components, making it simple to only see the gizmos you need.
· Support for setting a world size to render all icons with makes it simple to only see nearby icons.
· Scripting Execution Order
· Unity now gives you explicit control over the execution order in your scripts. Awake, OnEnable and Update calls are sorted by execution order. Execution order can be defined on a ‘per script’ basis in an easy-to-understand dialog.
· Downloadable content with caching for complete scenes and asset bundles
· Caching now works on all platforms. PC/Mac Standalone players and iOS/Android players have access to a 4 GiB dedicated cache for each application. The webplayer has a 50mb shared cache. A larger application-specific WebPlayer cache can be acquired from Unity Technologies. Caching of course greatly improves loading time not only due to the removed download, but also because the cached files are stored already decompressed on disk. Using the caching feature also greatly reduces memory usage since Unity doens't need to keep any additional data in memory. It is strongly recommended that you always use the caching API for large assets.
· A new function BuildPipeline.BuildStreamedSceneAssetBundle makes it easy to create entire scenes and their dependencies into an asset bundle and download them on demand.
· Downloading and streaming with the WWW class uses way less memory now. Especially significant when loading from disc using the file:// protocol. You can now load much bigger AssetBundles from disc without running out of memory.

Editor:
· Debug.DrawLine and Debug.DrawRay now has an optional parameter to control the duration of time a debug line should be rendered.
· New mouse event for MonoBehaviour: OnMouseUpAsButton. It is only called when the mouse is released over the same GUIElement or Collider as it was pressed.
· New interface for ObjectField that controls if scene objects should be assignable to the object field or not. Old interface marked as obsolete since it allowed invalid references e.g assets with with references to scene objects.
· Primitive Colliders can now be modified in Scene View by holding down SHIFT.
· The preview in the Inspector is now resizable and no longer part of the scroll-view.
Shadows:
· Directional Lights got new shadow projection mode, Stable Fit (default for new projects; change in Quality Settings). Old behaviour is Close Fit. Stable Fit results in slightly lower resolution, but shadow boundaries do not shimmer/wobble when rotating the camera.
· Much improved shadow caster culling (less draw calls). Better sorting of shadow casters for GPU efficiency.
· Added Very High shadow resolution option.
Skinning:
· SSE2 optimized skinning for Windows & Intel Macs. Improved multithreaded skinning efficiency on Macs.
Shaders:
· #pragma exclude_renderers/only_renderers can now use "shaderonly" (GLES2.0, 360, PS3 etc.) keyword.
· tex2Dgrad and tex2Dlod are supported when cross-compiling shaders into GLSL.
· Ability to access per-vertex light data in all platforms including OpenGL ES 2.0. Use float4 unity_LightPosition[4], unity_LightColor[4], unity_LightAtten[4].
· Added mobile optimized VertexLit and Unlit shaders.
Image Effects & Water:
· There’s a big upgrade to image effects & water. Both have been optimized for performance and, at the same time, visual quality has been improved. They’re also easier to tweak for artists.

Graphics:
· Deferred Lighting is able to use Occlusion Culling to cull invisible Point & Spot lights.
· Explicit control over VBlank Sync Count allows for more stable framerates. Quality Settings - Framesync flags: 'VBlank Sync Count' can now be set to 'Don't Sync' 'Every VBlank' or 'Every Second VBlank'
· Faster Point & Spot light rendering in Deferred Lighting (draws a more compact light shape).
· Optimized light culling in Forward rendering.
· Optimized per-vertex lighting in GLES 2.0 when fixed function shaders are used.
· Added Shader.WarmupAllShaders() to help reduce shader loading related hiccups.
· Added support for precomputed bounding volumes for Skinned Mesh Renderer and the animation component. This improves performance and lets you better cull animations & skinned meshes with minimal CPU overhead.

iOS:
· Added Terrain support for iOS.
· Added Gyroscope support.
· EAGLView wrapped into UIViewController / iOS native style of autorotation. Also added non-animated autorotation path. Corresponding option added to PlayerSettings.
· Added explicit null check option to the AOT code output, which should produce NullReference exceptions without causing SIGABRT in Xcode. Enabled when development player is selected and script debugging enabled.
· Improved automatic plugin inclusion for iOS. Now main.mm / AppController.mm could be substituted by the one supplied in Plugins/iOS.
· Mobile Quality Settings default to "Simple".
· Improved iOS project postprocessing performance. Runtime libs could be symlinked by checking appropriate option in Build Settings panel.
· Parallel AOT cross compilation for faster game build times.
· iOS SDK selection defaults to "latest".

Android:

· Build settings properly reflect changes to moving(renaming) scenes.

Graphics:
Improvements:
Major performance improvements in OpenGL ES 2.0 (iOS / Android):
· Much improved performance of shaders that are compiled from Cg/HLSL (e.g. Diffuse for directional light is about 2x faster on iPhone 3Gs). Now fixed/half/float types in Cg map to lowp/mediump/highp precision in GLSL. Use lowest precision type in your shaders!
· Improved GLSL shader optimizer.
· Changed normal map compression approach for mobile platforms. It's much faster now!
· Fog mode can be changed in Render Settings (also from scripts): Linear, Exp, Exp2 (default).
· Rendering performance optimizations (lower CPU overhead, less memory consumption).
Shadows:
· Forward rendering path supports Point & Spot light shadows again, as well as multiple shadowing lights! Note that by default shaders do not have this enabled, use fullforwardshadows surface shader directive to enable the behavior.
· Directional Light soft shadows blur width and fadeout speed can be adjusted in Inspector or via script.
· Exposed Light.shadowBias to scripting.
· Built-in shaders that perform Deferred Lighting, directional light shadow gathering in Deferred Lighting, and directional light shadow blurring can be overriden. Just drop your own shaders with the same names into the project.
· Deferred light buffer can be accessed from from Image Effects or other shaders (_LightBuffer).
Surface Shader improvements:
· support world-space normal as input (worldNormal).
· fullforwardshadows directive to enable all shadows from any lights in forward rendering loop.
· dualforward directive to enable dual lightmaps in Forward rendering.
· decal:blend mode for shaders used on decal-like surfaces.
· nolightmap directive to exclude lightmap support (makes shaders smaller).
· noambient directive to not apply ambient nor SH lighting.
· halfasview directive to compute normalized half-direction per-vertex, and pass that to the lighting function. Results in faster Specular-type shaders, however view direction won't be entirely correct.
· approxview directive to compute normalized view direction per-vertex instead of per-pixel. Results in faster Specular-type shaders, however view direction won't be entirely correct when camera gets close to surface.
· noforwardadd directive to skip generating forward additive pass. Will make a shader support one full directional light; all other lights will be per-vertex/SH.
· Shaders: #pragma glsl_no_auto_normalization directive to not auto-normalize normals & tangents in OpenGL ES 2.0 shaders.
· Shaders: Added TransformViewToProjection to do this properly on mobile devices with regard to orientation (on non-mobile it will be usual multiplication by diagonal terms of projection matrix).
· Shaders: Added per vertex lit tree shaders previously used in the Bootcamp demo. To be used with Tree Creator trees and located in "Nature/Tree Creator Leaves Fast".
· Desktop GLSL shaders now allow OpenGL ES precision types to be used.
· Added GL.GetGPUProjectionMatrix that returns actual projection matrix that will be used in shaders.
· Added support for 16bit RenderTextures.
· Scaled meshes are now only recreated if the scale has actually changed. This improves performance hiccups on same games.
· Texture2D.GetPixel and friends work on RGBA32 textures (common case for uncompressed textures on mobile platforms) in addition to ARGB32 ones.
· Texture2D.Apply and Texture2D.PackTextures now have additional parameter makeNoLongerReadable (default to false) that will mark Texture as not Readable, and free up system memory after uploading to GPU.

Fixes:
Shaders: Bunch of fixes to Cg->GLSL shader translator:
· Translates 'half' and 'fixed' matrix types properly (previously 'half' was translated to high precision, and 'fixed' was not supported).
· Support lit() built-in function.
· Fixes to swizzles on floats.
· Support static qualifier.
· Better handling of 2D matrix indexing, e.g. matrix[i][j].
· Shaders: fixed mis-compilation of matrix constructors & matrix indexing when translating shaders to GLSL.

· Shaders: Postprocess Direct3D pixel shaders that come close to 64 instruction limit to work around a crash on Intel GMA 950.
· Shaders: Fix some bogus error messages when loading Direct3D shaders.
· Surface Shaders: in case of syntax errors, proper line numbers are reported now... how cool is that? ;)

· Fixed rendering of scenes containing objects with odd-negative scale in deferred when any of the lights was casting shadows.
· Fixed Deferred Lighting not respecting camera's Don't Clear mode.

· When duplicating a dirty asset its preview in the Object Picker is incorrect until dirty again.

What's new in Unity 3.1.0:

November 26th, 2010

New Features:
· Managed .NET DLLs can now be placed in the project folder and can contain script code, including MonoBehaviours, EditorWindows and ScriptableObjects. This allows you to move any code into a DLL, making code sharing between projects easier, and making it easier for middleware developers to create libraries without sharing the source code. This was introduced in Unity 3.0 but was not mentioned in the release notes.
· Scripting: Added GL.InvalidateState() to flush the internal renderstate cache in Unity. This is mostly useful when writing native code plugins that access the 3D device.
· Audio: Added AudioSettings.outputSampleRate. Returns the mixer's output rate; use this to calculate the precise hertz range returned from GetSpectrumData().

Fixes:
· Editor: Fixed out of memory errors when editing very large terrains due to the Undo system.
· Editor: Fixed "too many open files" error when reimporting a large project with many shaders on Mac OS X.
· Editor: Some textures would not say "Texture not yet compressed" when importing with the "Compress Textures" preference turned off.
· Editor: Fixed a bug where upgrading a Unity 2.x project with normal maps would leave some normal maps not marked as Normalmap type properly.
· Terrain Engine: Unity 2.x Soft Vegetation tree shaders had lighting upside down :)
· Shaders: fixed Surface Shader compilation errors with large custom output structures.
· Shaders: wrong syntax in UnityCG.glslinc file (for GLSL shaders).
· Graphics: fixed Projector crash in some circumstances.
· Graphics: fixed tangent vectors not bound correctly with GLSL shaders on some GPUs.
· Graphics: fixed dynamic batching corrupting vertex colors on Direct3D.
· Graphics: fixed GL.TRIANGLES rendering with large triangle counts on Direct3D.
