Logback 1.3.x supports jdk1.8

Version strategy

Logback 1.3.x supports the Java EE edition whereas logback 1.4.x supports Jakarta EE, otherwise the two versions are feature identical.

Given that downstream users are likely to depend on either Java EE or (in the javax namespace) or on Jakarta EE (in the jakarta namespace) in their projects, it was deemed important for logback to support both alternatives.

As such, logback 1.3.x supports the Java EE edition whereas logback 1.4.x supports Jakarta EE, otherwise the two versions are feature identical. Here is a summary of the differences:

Logback version	JDK	Enterprise Edition	SLF4J version
1.3.x	8	Java EE (javax.* namespace)	2.0
1.4.x	11	Jakarta EE (jakarta.* namespace)	2.0

logback-core dependencies

Logback-core version	Servlet-api version (optional)	mail-api version (optional)
1.3.x	javax.servlet 4.0.1	javax.mail 1.6.2
1.4.x	jakarta.servlet 5.0.0	jakarta.mail 2.0.1
