Tomcat 8.5.54 (markt)
Catalina
Fix: Ensure all URL patterns provided via web.xml are %nn decoded consistently using the encoding of the web.xml file where specified and UTF-8 where no explicit encoding is specified. (markt)
Update: Allow a comma separated list of class names for the org.apache.tomcat.util.digester.PROPERTY_SOURCE system property. (remm)
Fix: 64149: Avoid NPE when using the access log valve without a pattern. (remm)
Fix: 64226: Reset timezone after parsing a date since the date format is reused. Test case submitted by Gary Thomas. (remm)
Fix: 64247: Using a wildcard for jarsToSkip should not override a possibly present jarsToScan. Based on code submitted by Iridias. (remm)
Fix: 64265: Fix ETag comparison performed by the default servlet. The default servlet always uses weak comparison. (markt)
Fix: Add support for default values when using ${...} property replacement in configuration files. Based on a pull request provided by Bernd Bohmann. (markt)
Coyote
Add: When configuring an HTTP Connector, warn if the encoding specified for URIEncoding is not a superset of US-ASCII as required by RFC7230. (markt)
Fix: 64240: Ensure that HTTP/0.9 requests that contain additional data on the request line after the URI are treated consistently. Such requests will now always be treated as HTTP/1.1. (markt)
Add: Expose the HTTP/2 connection ID and stream ID to applications via the request attributes org.apache.coyote.connectionID and org.apache.coyote.streamID respectively. (markt)
Add: Replace the system property org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH with the Connector attribute encodedSolidusHandling that adds an additional option to pass the %2f sequence through to the application without decoding it in addition to rejecting such sequences and decoding such sequences. (markt)
Add: Expose the associated HttpServletRequest to the CookieProcessor when generating a cookie header so the header can be tailored based on the properties of the request, such as the user agent, if required. Based on a patch by Lazar Kirchev. (markt)
Jasper
Add: Add support for specifying Java 14 (with the value 14) and Java 15 (with the value 15) as the compiler source and/or compiler target for JSP compilation. If used with an ECJ version that does not support these values, a warning will be logged and the latest supported version will used. (markt)
Cluster
Code: Refactor the creation of DeltaRequest objects to make it simpler to use custom implementations. Based on a pull request provided by Thomas Stock. (markt)
Web applications
Fix: Correct the documentation web application to remove references to the org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH system property changing how the sequence %5c is interpretted in a URI. (markt)
Other
Add: Improve the quality and expand the coverage of the French translations provided with Apache Tomcat. Contribution provided by Tom Bens. (remm)
Add: Expand the coverage of the Chinese translations provided with Apache Tomcat. Contribution provided by Lee Yazhou. (markt)

Fix: Depreacted the LOGGING_CONFIG environment variable and replace it with the CATALINA_LOGGING_CONFIG environment variable to avoid clashes with other components that use LOGGING_CONFIG. (markt)
2020-03-16 Tomcat 8.5.53 (markt)
Coyote
Fix: 64210: Correct a regression in the improvements to HTTP header validation that caused requests to be incorrectly treated as invalid if a CRLF sequence was split between TCP packets. Improve validation of request lines, including for HTTP/0.9 requests. (markt)
Other
Fix: 64206: Correct a regression introduced in 8.5.51 that meant that the HTTP port specified when using the Windows Installer was ignored and 8080 was always used. (markt)
not released Tomcat 8.5.52 (markt)
Catalina
Fix: Store config compatibility with HostWebXmlCacheCleaner listener. (remm)
Fix: Modify the RewriteValve to use ServletRequest.getServerName() to populate the HTTP_HOST variable rather than extracting it from the Host header as this allows HTTP/2 to be supported. (markt)
Code: Remove PushBuilder from the deprecated Servlet 4 Preview API. Users still depending on this feature should ideally upgrade to Tomcat 9.0.x. If upgrade is not possible, application code should cast to the internal Tomcat implementation classes. (markt)
Fix: Switch Tomcat embedded to loading MIME type mappings from a property file generated from the default web.xml so the MIME type mappings are consistent regardless of how Tomcat is started. (markt)
Fix: Missing store config attributes for Resources elements. (remm)
Fix: 64153: Ensure that the parent for the web application class loader is set consistently. (markt)
Fix: 64166: Ensure that the names returned by HttpServletResponse.getHeaderNames() are unique. (markt)

Fix: 64141: If using a CA certificate, remove a default value for the truststore file when not using a JSSE configuration. (remm)
Fix: Improve robustness of OpenSSLEngine shutdown. Based on code submitted by Manuel Dominguez Sarmiento. (remm)
Fix: Add the TLS request attributes used by IIS to the attributes that an AJP Connector will always accept. (markt)
Fix: A zero length AJP secret will now behave as if it has not been specified. (remm)
Fix: 64188: If an error occurs while committing or flushing the response when using a multiplexing protocol like HTTP/2 that requires the channel to be closed but not the connection, just close the channel and allow the other channels using the connection to continue. Based on a suggestion from Alejandro Anadon. (markt)
Fix: Correct the semantics of getEnableSessionCreation and setEnableSessionCreation for OpenSSLEngine. Pull request provided by Alexander Scheel. (markt)
Fix: Allow async requests to complete cleanly when the Connector is paused before complete() is called on a container thread. (markt)
Jasper
Code: Parameterize JSP version and API class names in localization messages to allow simpler re-use between major versions. (markt)
Fix: Ensure that TLD files listed in the jsp-config section of web.xml that are registered in the uriTldResourcePathMap with the URI specified in web.xml are also registered with the URI in the TLD file if it is different. Patch provided by Markus Lottmann. (markt)

Fix: 64011: JNDIRealm no longer authenticates to LDAP. (michaelo)
Fix: 64021: Ensure that container provided SCIs are always loaded before application provided SCIs. Note that where both the container and the application provide the same SCI, it is the application provided SCI that will be used. (markt)
Fix: SCI definitions from JARs unpacked into WEB-INF/classes are now handled consistently and will always be found irrespective of whether the web application defines a JAR ordering or not. (markt)
Fix: 64023: Skip null-valued session attributes when deserializing sessions. (schultz)
Fix: Do not throw a NullPointerException when an MBean or operation cannot be found by the JMXProxyServlet. (schultz)
Update: 64067: Allow more than one parameter when defining RewriteMaps. (fschumacher)
Fix: 64074: InputStreams for directories obtained from resource URLs now return a directory listing consistent with the behaviour of FileURLConnection.

Update: Disable (comment out in server.xml) the AJP/1.3 connector by default. (markt)
Update: Change the default bind address for the AJP/1.3 connector to be the loopback address. (markt)
Add: Rename the requiredSecret attribute of the AJP/1.3 Connector to secret and add a new attribute secretRequired that defaults to true. When secretRequired is true the AJP/1.3 Connector will not start unless the secret attribute is configured to a non-null, non-zero length String. (markt)
Add: Add a new attribute, allowedRequestAttributesPattern to the AJP/1.3 Connector. Requests with unrecognised attributes will be blocked with a 403. (markt)

Fix: Make a best effort attempt to clean-up if a request fails during processing due to an OutOfMemoryException. (markt)
Fix: Ensure that, when static resource caching is enabled for a web application, all access to static files (including JSP files) goes via the cache so that a consistent view of the static files is seen. Prior to this change it was possible to see an updated last modified time but the content would be that prior to the modification. (markt)
Update: 63905 Clean up Tomcat CSS. (michaelo)

not released Tomcat 8.5.44 (markt)
Catalina
Add: 62258: Don't trigger the standard error page mechanism when the error has caused the connection to the client to be closed as no-one will ever see the error page. (markt)
Add: 62496: Add option to write auth information (remote user/auth type) to response headers. (michaelo)
Add: 51497: Add an option, ipv6Canonical, to the AccessLogValve that causes IPv6 addresses to be output in canonical form defined by RFC 5952. (ognjen/markt)
Add: 57665: Add support for the X-Forwarded-Host header to the RemoteIpFilter and RemoteIpValve. (markt)
Fix: 63550: Only try the alternateURL in the JNDIRealm if one has been specified. (markt)
Add: 63556: Mark request as forwarded in RemoteIpValve and RemoteIpFilter (michaelo)
Fix: 63579: Correct parsing of malformed OPTIONS requests and reject them with a 400 response rather than triggering an internal error that results in a 500 response. (markt)
Fix: 63608: Align the implementation of the negative match feature for patterns used with the RewriteValve with the description in the documentation. (markt)
Update: 63627: Implement more fine-grained handling in RealmBase.authenticate(GSSContext, boolean). (michaelo)
Fix: If an unhandled exception occurs on a asynchronous thread started via AsyncContext.start(Runnable), process it using the standard error page mechanism. (markt)
Fix: Discard large byte buffers allocated using setBufferSize when recycling the request. (remm)
Fix: Correct version information in X-Powered-By header. (markt)
Fix: Avoid a NullPointerException in the CrawlerSessionManagerValve if no ROOT Context is deployed and a request does not map to any of the other deployed Contexts. Patch provided by Jop Zinkweg. (markt)
Fix: 63636: Context.findRoleMapping() never called in StandardWrapper.findSecurityReference(). (michaelo)
Coyote
Fix: 63524: Improve the handling of PEM file based keys and certificates that do not include a full certificate chain when configuring the internal, in-memory key store. Improve the handling of PKCS#1 formatted private keys when configuring the internal, in-memory key store. (markt)

Fix: Correct parsing of invalid host names that contain bytes in the range 128 to 255 and reject them with a 400 response rather than triggering an internal error that results in a 500 response. (markt)
Fix: 63571: Allow users to configure infinite TLS session caches and/or timeouts. (markt)
Fix: 63578: Improve handling of invalid requests so that 400 responses are returned to the client rather than 500 responses. (markt)
Fix: Fix h2spec test suite failure. It is an error if a Huffman encoded string literal contains the EOS symbol. (jfclere)
Add: Connections that fail the TLS handshake will now appear in the access logs with a 400 status code. (markt)
Fix: Timeouts for HTTP/2 connections were not always correctly handled leaving some connections open for longer than expected. (markt)
Add: Expand the HTTP/2 excessive overhead protection to cover various forms of abusive client behaviour and close the connection if any such behaviour is detected. (markt)
Fix: Fix a crash on shutdown with the APR/native connector when a blocking I/O operation was still in progress when the connector stopped. (markt)
Web applications
Fix: 63597: Update the custom 404 error page for the Host Manager to take account of previous refactoring so that the page is used for 404 errors rather than falling back to the default error page. (markt)
Other
Fix: 55969: Tighten up the security of the Apache Tomcat installation created by the Windows installer. Change the default shutdown port used by the Windows installer from 8005 to -1 (disabled). Limit access to the chosen installation directory to local administrators, Local System and Local Service. (markt)
Update: 62696: The digital signature for the Windows installer now uses SHA-256 for hashes. (markt)
Fix: 63285: Modify service.bat so that when installing a Windows service, by default, it changes the name of the executables used by the Windows service to match the service name. This makes the installation behaviour consistent with the Windows installer. The original executable names will be restored when the Windows service is removed. The renaming can be disabled by using the new --no-rename option after the service name. (markt)
Update: Switch from Checkstyle to the JRE6 backport and update to version 8.22. This allows Tomcat 8.5 to use the newer Checkstyle releases while still building with Java 7. (markt)
Add: 63285: Add an option to service.bat so that when installing a Windows service, the name of the executables used by the Windows service may be changed to match the service name. This makes the installation behaviour consistent with the Windows installer. The original executable names will be restored when the Windows service is removed. The renaming can be enabled by using the new --rename option after the service name. (markt)
Update: 63310: Update to Commons Daemon 1.2.0. This provides improved support for Java 11. This also changes the user configured by the Windows installer for the Windows service from Local System to the lower privileged Local Service. (markt)
Fix: 63567: Restore the passing of $LOGGING_MANAGER to the jvm in catalina.sh when calling stop. (markt)
Update: Update the internal fork of Commons Codec to 3ebef4a (2018-08-01) to pick up the fix for CODEC-134. (markt)

Update: Update the internal fork of Commons DBCP2 to 87d9e3a (2018-08-01) to pick up the changes Commons DBCP2 2.7.0 and DBCP-555. (markt)
Update: 63648: Update the test TLS keys and certificates used in the test suite to replace the keys and certificates that are about to expire. (markt)
2019-07-09 Tomcat 8.5.43 (markt)
Catalina
Update: Modify the Default and WebDAV Servlets so that a 405 status code is returned for PUT and DELETE requests when disabled via the readonly initialisation parameter.
Fix: Align the contents of the Allow header with the response code for the Default and WebDAV Servlets. For any given resource a method that returns a 405 status code will not be listed in the Allow header and a method listed in the Allow header will not return a 405 status code. (markt)
Fix: When using WebDAV to copy a file resource to a destination that requires a collection to be overwritten, ensure that the operation succeeds rather than fails (with a 500 response). This enables Tomcat to pass two additional tests from the Litmus WebDAV test suite. (markt)
Fix: 49464: Improve the Default Servlet's handling of static files when the file encoding is not compatible with the required response encoding. (markt)
Fix: Fix typo in UTF-32LE charset name. Patch by zhanhb vi Github. (fschumacher)
Add: 58590: Add the ability for a UserDatabase to monitor the backing XML file for changes and reload the source file if a change in the last modified time is detected. This is enabled by default meaning that changes to $CATALINA_BASE/conf/tomcat-users.xml will now take effect a short time after the file is saved. (markt)
Fix: Improve parsing of Range request headers. (markt)
Fix: Range headers that specify a range unit Tomcat does not recognise should be ignored rather than triggering a 416 response. Based on a pull request by zhanhb. (markt)
Fix: When comparing a date from a If-Range header, an exact match is required. Based on a pull request by zhanhb. (markt)
Fix: Add an option to the default servlet to disable processing of PUT requests with Content-Range headers as partial PUTs. The default behaviour (processing as partial PUT) is unchanged. Based on a pull request by zhanhb. (markt)
Fix: Improve parsing of Content-Range headers. (markt)
Fix: Ensure that the HEAD response is consistent with the GET response when HttpServlet is relied upon to generate the HEAD response and the GET response uses chunking. (markt)
Update: Update the recommended minimum Tomcat Native version to 1.2.23. (markt)
Coyote
Fix: Avoid a potential hang when a client connects using TLS 1.0 to a Tomcat HTTPS connector configured to use NIO or NIO with OpenSSL 1.1.1 or later. (markt)
Fix: Once a URI is identified as invalid don't attempt to process it further. Based on a PR by Alex Repert. (markt)
Fix: Fix to avoid the possibility of long poll times for individual pollers when using multiple pollers with APR. (markt)
Fix: Refactor the fix for 63205 so it only applies when using PKCS12 keystores as regressions have been reported with some other keystore types. (markt)
Jasper
Add: Include file names in error messages if SMAP processor is unable to delete or rename a class file during SMAP generation. (markt)
WebSocket
Fix: 63521: As required by the WebSocket specification, if a POJO that is deployed as a result of the SCI scan for annotated POJOs is subsequently deployed via the programmatic API ignore the programmatic deployment. (markt)
Other
Code: Switch i18n message files to use UTF-8 and convert to ASCII at build time. (markt)
Fix: 63523: Restore SSLUtilBase methods as protected to preserve compatibility. (remm)
Fix: Switch the check for terminal availability to test for stdin as using stdout does not work when output is piped to another process. Patch provided by Radosław Józwik. (markt)
2019-06-07 Tomcat 8.5.42 (markt)
Catalina
Add: 57287: Add file sorting to DefaultServlet (schultz)
Fix: Ensure that the default servlet reads the entire global XSLT file if one is defined. Identified by Coverity Scan. (markt)
Fix: Avoid potential NullPointerException when generating an HTTP Allow header. Identified by Coverity Scan. (markt)
Add: Remove any fragment included in the target path used to obtain a RequestDispatcher. The requested target path is logged as a warning since this is an application error. (markt)
Coyote
Update: Add additional NIO2 style read and write methods closer to core NIO2, for possible use with an asynchronous workflow like CompletableFuture. (remm)
Fix: Avoid useless exception wrapping in async IO. (remm)
Fix: 63412: Security manager failure when using the async IO API from a webapp. (remm)
Fix: Fix concurrency issue that lead to incorrect HTTP/2 connection timeout. (remm/markt)
Update: Reduce the default for maxConcurrentStreams on the Http2Protocol from 200 to 100 to align with typical defaults for HTTP/2 implementations. (markt)
Update: Reduce the default HTTP/2 header list size from 4GB to 32kB to align with typical HTTP/2 implementations. (markt)
Add: Add support for same-site cookie attribute. Patch provided by John Kelly. (markt)
Fix: Correct a bug in the stream flushing code that could lead to multiple threads processing the stream concurrently which in turn could cause errors processing the stream. (markt)
Cluster
Fix: 62841: Refactor the DeltaRequest serialization to reduce the window during which the DeltaSession is locked and to remove a potential cause of deadlocks during serialization. (markt)
Fix: 63441: Further streamline the processing of session creation messages in the DeltaManager to reduce the possibility of a session update message being processed before the session has been created. (markt)
Tribes
Fix: Treat NoRouteToHostException the same way as SocketTimeoutException when checking the health of group members. This avoids a SEVERE log message every time the check is performed when the host associated with a group member is not powered on. (markt)
Other
Update: Switch from FindBugs to SpotBugs. (fschumacher)
Fix: 63403: Fix TestHttp2InitialConnection test failures when running with a non-English locale. (kkolinko)
Fix: Use the test command to check for terminal availability rather than the tty command since the tty based test fails on non-English locales. (markt)
2019-05-13 Tomcat 8.5.41 (markt)

Fix: 63333: Override the isAvailable() method in the JAASRealm so that only login failures caused by invalid credentials trigger account lock out when the LockOutRealm is in use. Patch provided by jchobantonov. (markt)
Coyote
Fix: When running on newer JREs that don't support SSLv2Hello, don't warn that it is not available unless explicitly configured. (markt)
Code: Refactor Hostname validation to improve performance. Patch provided by Uwe Hees. (markt)
Fix: Expand HTTP/2 timeout handling to include connection window exhaustion on write. This is the fix for CVE-2019-10072. (markt)
Other
Fix: 63335: Ensure that stack traces written by the OneLineFormatter are fully indented. The entire stack trace is now indented by an additional TAB character. (markt)
Fix: When using the OneLineFormatter, don't print a blank line in the log after printing a stack trace. (markt)
Update: Update the internal fork of Apache Commons DBCP 2 to dcdbc72 (2019-04-24) to pick up some clean-up and enhancements less the JDBC 4.2 related changes that require Java 8. (markt)
Update: Update the internal fork of Apache Commons Pool 2 to 0664f4d (2019-04-30) to pick up some enhancements and bug fixes. (markt)
Update: Update the internal fork of Apache Commons FileUpload to 41e4047 (2019-04-24) pick up some enhancements. (markt)
2019-04-12 Tomcat 8.5.40 (markt)
Catalina
Fix: 63196: Provide a default (X-Forwarded-Proto) for the protocolHeader attribute of the RemoteIpFilter and RemoteIpValve. (markt)
Fix: 63235: Refactor Charset cache to reduce start time. (markt)
Fix: 63249: Use a consistent log level (WARN) when logging the failure to register or deregister a JMX Bean. (markt)
Fix: 63249: Use a consistent log level (ERROR) when logging the LifecycleException associated with the failure to start or stop a component. (markt)
Fix: When the SSI directive fsize is used with an invalid target, return a file size of - rather than 1k. (markt)
Fix: 63251: Implement a work-around for a known JRE bug (JDK-8194653) that may cause a dead-lock when Tomcat starts. (markt)
Fix: 63275: When using a RequestDispatcher ensure that HttpServletRequest.getContextPath() returns an encoded path in the dispatched request. (markt)
Fix: 63286: Document the differences in behaviour between the LogFormat directive in httpd and the pattern attribute in the AccessLogValve for %D and %T. (markt)
Fix: 63311: Add support for https URLs to the local resolver within Tomcat used to resolve standard XML DTDs and schemas when Tomcat is configured to validate XML configuration files such as web.xml. (markt)
Fix: Encode the output of the SSI printenv command. This is the fix for CVE-2019-0221. (markt)
Code: Use constants for SSI encoding values. (markt)
Add: When the CGI Servlet is configured with enableCmdLineArguments set to true, limit the encoded form of the individual command line arguments to those values allowed by RFC 3875. This restriction may be relaxed by the use of the new initialisation parameter cmdLineArgumentsEncoded. (markt)
Add: When the CGI Servlet is configured with enableCmdLineArguments set to true, limit the decoded form of the individual command line arguments to known safe values when running on Windows. This restriction may be relaxed by the use of the new initialisation parameter cmdLineArgumentsDecoded. This is the fix for CVE-2019-0232. (markt)
Update: Change the default for the enableCmdLineArguments parameter of the CGI servlet from true to false as additional hardening against CVE-2019-0232. (markt)
Coyote
Fix: Fix bad interaction between NIO2 async read API and the regular read. (remm)
Fix: Refactor NIO2 write pending strategy for the classic IO API. (remm)
Fix: Harmonize NIO2 isReadyForWrite with isReadyForRead code. (remm)
Fix: When using a JSSE TLS connector that supported ALPN (Java 9 onwards) and a protocol was not negotiated, Tomcat failed to fallback to HTTP/1.1 and instead dropped the connection. (markt)
Fix: Correct a regression in the TLS connector refactoring in Tomcat 9.0.17 that prevented the use of PKCS#8 private keys with OpenSSL based connectors. (markt)
Fix: When performing an upgrade from HTTP/1.1 to HTTP/2, ensure that any query string present in the original HTTP/1.1 request is passed to the HTTP/2 request processing. (markt)
Fix: When Tomcat writes a final response without reading all of an HTTP/2 request, reset the stream to inform the client that the remaining request body is not required. (markt)
Fix: 63312: Correct a regression in the error page handling that prevented error pages from issuing redirects or taking other action that required the response status code to be changed. (markt)
Jasper
Add: Add support for specifying Java 11 (with the value 11) as the compiler source and/or compiler target for JSP compilation. (markt)
Add: Add support for specifying Java 12 (with the value 12) and Java 13 (with the value 13) as the compiler source and/or compiler target for JSP compilation. If used with an ECJ version that does not support these values, a warning will be logged and the latest supported version will used. Based on a patch by Thomas Collignon. (markt)
WebSocket
Fix: Improve the handling of exceptions during TLS handshakes for the WebSocket client. (markt)
Web applications
Fix: 63184: Expand the SSI documentation to provide more information on the supported directives and their attributes. Patch provided by nightwatchcyber. (markt)

2019-03-19 Tomcat 8.5.39 (markt)
Catalina
Fix: Minor HTTP/2 push fixes. (remm)
Fix: Refactor how cookies are transferred from the base request to a PushBuilder so that they are accessible, and may be edited, via the standard PushBuilder methods for working with HTTP headers. (markt)
Add: Refactor error handling to enable errors that occur before processing is passed to the application to be handled by the application provided error handling and/or the container provided error handling (ErrorReportValve) as appropriate. (markt)
Add: Pass 404 errors triggered by a missing ROOT web application to the container error handling to generate the response body. (markt)
Add: Pass 400 errors triggered by invalid request targets to the container error handling to generate the response body. (markt)
Add: Pass errors triggered by invalid requests or unavailable services to the application provided error handling and/or the container provided error handling (ErrorReportValve) as appropriate. (markt)
Code: Refactor the MBean implementations for the internal Tomcat components to reduce code duplication. (markt)
Update: Simplify the value of jarsToSkip property in catalina.properties file for tomcat-i18n jar files. Use prefix pattern instead of listing each language. (kkolinko)
Fix: Restore the getter and setter for the access log valve attribute maxLogMessageBufferSize that were accidentally removed. (markt)
Add: 63206: Add a new attribute to Context - createUploadTargets which, if true enables Tomcat to create the temporary upload location used by a Servlet if the location specified by the Servlet does not already exist. The default value is false. (markt)
Fix: 63210: Ensure that the Apache Commons DBCP 2 based default connection pool is correctly shutdown when it is no longer required. This ensures that a non-daemon thread is not left running that will prevent Tomcat from shutting down cleanly. (markt)
Fix: 63213: Ensure the correct escaping of group names when searching for nested groups when the JNDIRealm is configured with roleNested set to true. (markt)
Fix: 63236: Use String.intern() as suggested by Phillip Webb to reduce memory wasted due to String duplication. This changes saves ~245k when starting a clean installation. With additional thanks to YourKit Java profiler for helping to track down the wasted memory and the root causes. (markt)
Fix: 63246: Fix a potential NullPointerException when calling AsyncContext.dispatch(). (markt)
Coyote
Fix: Ensure that the toString(), toBytes() and toChars() methods of MessageBytes behave consistently and do not throw a NullPointerException both on newly created objects and immediately after a call to recycle(). This should not impact typical Tomcat users. It may impact users who use these classes directly in their own code. (markt)
Fix: When performing an HTTP/1.1 upgrade to HTTP/2 (h2c) ensure that the hostname and port from the HTTP/1.1 Host header of the upgraded request are made available via the standard methods ServletRequest.getServerName() and ServletRequest.getServerPort(). (markt)
Fix: Make PEM file parser a public utility class. (remm)
Fix: Refactor the APR/Native endpoint TLS configuration code to enable JSSE style configuration - including JKS keystores - to be used with the APR/Native connector. (markt)
Add: With the TLS configuration refactoring, the configuration attributes sessionCacheSize and sessionTimeout are no longer limited to JSSE implementations. They may now be used with OpenSSL implementations as well. (markt)
Fix: Refactor NIO2 read pending strategy for the classic IO API. (remm)
Fix: 63182: Avoid extra read notifications for HTTP/1.1 with NIO2 when using asynchronous threads. (remm)
Add: 63205: Add a work-around for a known JRE KeyStore loading bug. (markt)
Update: Sync with NIO2 async API from Tomcat 9 branch. (remm)
Fix: NIO2 should try to use SocketTimeoutException everywhere rather than a mix of it and InterruptedByTimeout. (remm)
Fix: Correct an error in the request validation that meant that HTTP/2 push requests always resulted in a 400 response. (markt)
Fix: 63223: Correctly account for push requests when tracking currently active HTTP/2 streams. (markt)
Fix: Verify HTTP/2 stream is still writable before assuming a timeout occurred. (remm)
Fix: Avoid some overflow cases with OpenSSL to improve efficiency, as the OpenSSL engine has an internal buffer. (remm)
Fix: Harmonize HTTP/1.1 NIO2 keepalive code. (remm)
WebSocket
Code: Remove the STREAMS_DROP_EMPTY_MESSAGES system property that was introduced to work-around four failing TCK tests. An alternative solution has been implemented. Sending messages via getSendStream() and getSendWriter() will now only result in messages on the wire if data is written to the OutputStream or Writer. Writing zero length data will result in an empty message. Note that sending a message via an Encoder may result in the message being send via getSendStream() or getSendWriter(). (markt)
Web applications
Fix: Use client's preferred language for the Server Status page of the Manager web application. Review and fix several cases when the client's language preference was not respected in Manager and Host Manager web applications. (kkolinko)
Fix: Fix messages used by Manager and Host Manager web applications. Disambiguate message keys used when adding or removing a host. Improve display of summary values on the status page: separate terms and values with a whitespace. Improve wording of messages for expire sessions command. (kkolinko)
Fix: Do not add CSRF nonce parameter and suppress Referer header for external links in Manager and Host Manager web applications. (kkolinko)
Tribes
Fix: Ensure that members registered in the addSuspects list are static members. (kfujino)
Other
Add: Expand the coverage and quality of the Russian translations provided with Apache Tomcat. (kkolinko)
Fix: 63041: Revert the changes for 53930 that added support for the CATALINA_OUT_CMD environment variable as they prevented correct operation with systemd configurations that did not explicitly specify a PID file. (markt)
2019-02-08 Tomcat 8.5.38 (markt)
Catalina
Fix: 54741: Add a new method, Tomcat.addWebapp(String,URL), that allows a web application to be deployed from a URL when using Tomcat in embedded mode. (markt)
Fix: Ensure that the ServletOutputStream implementation is consistent with the requirements of asynchronous I/O and that all of the write methods use a single write rather than multiple writes. (markt)
Fix: Correct the Javadoc for Context.getDocBase() and Context.setDocBase() and remove text that indicates that a URL may be used for the docBase as this has not been the case for quite some time. (markt)
Add: Ensure that Tomcat is fully terminated when running as a service. (markt)
Code: Treat I/O errors during request body reads the same way as I/O errors during response body writes. The errors are treated as client side errors rather than server side errors and only logged at debug level. (markt)
Fix: 63038: Ensure that a ClassNotFoundException is thrown when attempting to load a class from a corrupted JAR file. (markt)
Add: Make the removal of leading and trailing whitespace from credentials passed to BASIC authentication configurable via a new attribute, trimCredentials on the BasicAuthenticator. (markt)
Fix: 63003: Extend the unloadDelay attribute on a Context to include in-flight asynchronous requests. (markt)
Add: 63026: Add a new attribute, forceDnHexEscape, to the JNDIRealm that forces escaping in the String representation of a distinguished name to use the \nn form. This may avoid issues with realms using Active Directory which appears to be more tolerant of optional escaping when the \nn form is used. (markt)
Fix: Avoid a swallowed (and therefore ignored) access failure during web application class loading when running under a SecurityManager. (markt)
Update: Update the recommended minimum Tomcat Native version to 1.2.21. (markt)
Fix: 63137: If the resources for a web application have been configured with multiple locations mapped to /WEB-INF/classes, ensure that all of those locations are used when building the web application class path. Patch provided by Marcin Gołębski. (markt)
Coyote
Add: 63009: Include the optional content-length header in HTTP/2 responses where an appropriate value is available. (markt)
Fix: 63022: Do not use the socket open state when using the wrapper isClosed method for NIO and NIO2, as it will disable all further processing. (remm)
Fix: Fix socket close discrepancies for NIO2, now the wrapper close is used everywhere except for socket accept problems. (remm)
Jasper
Fix: 63056: Correct a regression in the fix for 53737 that did not correctly scan the web application directory structure for JSPs. (markt)
Fix: Update the performance optimisation for using expressions in tags that depend on uninitialised tag attributes with implied scope to make the performance optimisation aware of the new public class (java.lang.Enum$EnumDesc) added in Java 12. (markt)
WebSocket
Fix: 57974: Ensure implementation of Session.getOpenSessions() returns correct value for both client-side and server-side calls. (markt)
Fix: 63019: Use payload remaining bytes rather than limit when writing. Submitted by Benoit Courtilly. (remm)
Fix: When running under a SecurityManager, ensure that the ServiceLoader look-up for the default javax.websocket.server.ServerEndpointConfig.Configurator implementation completes correctly rather than silently using the hard-coded fall-back. (markt)
Fix: Ensure that the network connection is closed if the client receives an I/O error trying to communicate with the server. (markt)
Fix: Ignore synthetic methods when scanning POJO methods. (markt)
Fix: Implement the requirements of section 5.2.1 of the WebSocket 1.1 specification and ensure that if the deployment of one Endpoint fails, no Endpoints are deployed for that web application. (markt)
Fix: Implement the requirements of section 4.3 of the WebSocket 1.1 specification and ensure that the deployment of an Endpoint fails if @PathParam is used with an invalid parameter type. (markt)
Fix: Ensure a DeploymentException rather than an IllegalArgumentException is thrown if a method annotated with @OnMessage does not conform to the requirements set out in the Javadoc. (markt)
Fix: Improve algorithm that determines if two @OnMessage annotations have been added for the same message type. Prior to this change some matches were missed. (markt)
Web applications
Fix: 63103: Remove the unused source.jsp file and associated tag from the examples web application as it is no longer used. (markt)
Fix: 63143: Ensure that the Manager web application respects the language preferences of the user as configured in the browser when the language of the default system locale is not English. (markt)
Tribes
Add: Add EncryptInterceptor to the portfolio of available clustering interceptors. This adds symmetric encryption of session data to Tomcat clustering regardless of the type of cluster manager or membership being used. (schultz)

not released Tomcat 8.5.36 (markt)
Catalina
Fix: 62788: Add explicit logging configuration to write log files using UTF-8 to align with Tomcat's use of UTF-8 by default elsewhere. (markt)
Fix: The default Servlet should not override a previously set content-type. (remm)
Add: 62897: Provide a property (clearReferencesThreadLocals) on the standard Context implementation that enables the check for memory leaks via ThreadLocals to be disabled because this check depends on the use of an API that has been deprecated in later versions of Java. (markt)
Fix: Fix more storeconfig issues with duplicated SSL attributes. (remm)
Fix: 62968: Avoid unnecessary (and relatively expensive) getResources() call in the Mapper when processing rule 7. (markt)
