This major version upgrade from 1.2.0 to 1.5.25 introduces significant breaking changes, including required updates to the Java Development Kit (JDK) and SLF4J library, and changes to internal APIs.
Highlights:
Java and SLF4J Version: Logback 1.4.x and higher require Java 11 (up from Java 8) and SLF4J 2.0.x (up from 1.7.x). This is a major dependency change that may require a broader update of the project's dependencies to avoid conflicts.
Java EE to Jakarta EE: Optional components like SMTPAppender have been migrated from the javax.* namespace (Java EE) to the jakarta.* namespace (Jakarta EE) starting in version 1.4.x.
Internal Configuration API (Joran): Logback's internal configuration system, Joran, was rewritten in version 1.3. Custom code that programmatically interacts with Joran will need to be adapted.
Source: Package documentation Recommendation: Before upgrading, ensure the project is compatible with Java 11 and SLF4J 2.0.x. Verify all dependencies to prevent SLF4J version conflicts. Review any custom code that interacts with Logback's configuration system and check for usage of optional components that now depend on Jakarta EE.
