2025-03-18 Release of logback version 1.5.18
• Added support for XZ compression for archived log files. Note that XZ compression requires Tukaani project's XZ library for Java. In case XZ compression is requested but the XZ library is missing, then logback will substitute GZ compression as a fallback. This feature was requested in issues/755.
• Removed references to java.security.AccessController class. This class has been deprecated for some time and is slated for removal in future JDK versions.
• A bit-wise identical binary of this version can be reproduced by building from source code at commit b2a02f0 associated with the tag v_1.5.18. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.
