[dependabot]

Bumps logback.version from 1.5.16 to 1.5.21.
Updates ch.qos.logback:logback-core from 1.5.16 to 1.5.21

Release notes

Sourced from ch.qos.logback:logback-core's releases.

Logback 1.5.20

2025-10-19 Release of logback version 1.5.20

• Due to potential vulnerabilities associated with dynamic, i.e. runtime, java code compilation and execution (using Janino), the 'condition' attribute within the <if> element is deprecated and will be removed in 2027.

An online migration service is provided to help with the transition.

The <condition> element, new in this version, admits custom PropertyEvaluator as a recommended alternative. See also the updated documentation on conditional configuration.

• Logback-classic's initialization procedure has been simplified by removing the step instantiating a SerializedModelConfigurator. However, it is still possible to set up SerializedModelConfigurator as a custom configurator.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 930fb15c993a4344bcecc6ba2225c12a2c38e676 associated with the tag v_1.5.20. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.19

2025-09-30 Release of logback version 1.5.19

• Disallow "new" operator in the condition attribute of <if> elements. This fixes an ACE vulnerability recorded as CVE-2025-11226.

• At initialization time, slightly better reporting about watched configuration files.

• Softer message regarding usage of ConsoleAppender and its potential impact on performance.

• In ViewStatusMessagesServlet, restrict processing of "Clear" button to POST method. This change was proposed by Ralf Wiebicke who also provided the relevant PR.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit e572d4f87f06674788eb3ca7148e8d1dffc615fa associated with the tag v_1.5.19. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.18

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 b2a02f065379a9b1ba5ff837fc08913b744774bc 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.

Logback 1.5.17

2025-02-25 Release of logback version 1.5.17

• Fixed Jansi 2.4.0 color-coded output not working on Windows CMD.exe console when the default terminal application is set to "Windows Console Host". This problem was reported in issues/753 by Michael Lyubkin.

• Fixed race condition occurring in case MDC class is initialized while org.slf4j.LoggerFactory is initializing logback-classic's LoggerContext. When this race conditions occurs, the MDCAdapter instance used by MDC does not match the instance used by logback-classic. This issue was reported in SLF4J issues/450. While logback-classic version 1.5.17 remains compatible with SLF4J versions in the 2.0.x series, fixing this particular MDC issue requires SLF4J version 2.0.17.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 10358724ed723b3745c010aa40cb02a2dfed4593 associated with the tag v_1.5.17. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.
