Apache Log4j Files

This minor release delivers all the fixes in the [2.25.0, 2.25.4] version range, plus some new fixes, and several other improvements and features.

Added

• Add a new ConfigurationFactory::getConfiguration method accepting multiple URIs (#3775, [#3921])
• Add and export org.apache.logging.log4j.core.pattern.NamedInstantPattern enabling users to programmatically access named date & time patterns supported by Pattern Layout (#3789)
• Add log4j.plugin.processor.minAllowedMessageKind annotation processor option to PluginProcessor to filter diagnostic messages by severity. This allows builds that treat compiler notes as errors (e.g. Maven with -Werror) to suppress informational notes emitted during normal plugin processing. ([https://github.com/apache/logging-log4j2/discussions/3380#3380], [#4063])
• Add missing setters to Rfc5424LayoutBuilder

Changed

• Ensure scripts in the global Scripts element have explicit names by throwing a ConfigurationException for unnamed ones. (#3176)
• Simplify file manager registry factory methods (#3968)

Deprecated

• Deprecated withers in builder classes in favor of setters. This change improves API consistency with Log4j Core 3 and helps users adapt to the upcoming changes. (#3750)

Fixed

• Fix script resolution failure when the Scripts element is placed after a ScriptRef in the configuration. (#3336)
• Fix ArrayIndexOutOfBoundsException thrown by ThrowableStackTraceRenderer when the stack trace is modified concurrently (#3940, [#3955])
• Fix SLF4JLogger.atFatal() returning atLevel(Level.TRACE) instead of atLevel(Level.FATAL). This was causing FATAL-level log events to be silently discarded when using the fluent API through the log4j-to-slf4j bridge. (#4068, [#4089])
• Fix Javadoc references across module boundaries (i.e., cross-references) (#4099, [#4100])
• Fix header write in RollingRandomAccessFileManager that was being incorrectly skipped if append=true and the file didn't exist before
• Fix a properties file configuration regression caused by not referenced loggers, appenders, and filters (#4036, [#4069])

Removed

• Remove the jvmrunargs lookup. (#3874)

Updated

• Update org.junit:junit-bom to version 5.13.4 (#3850)
• Update org.mongodb:bson to version 5.6.1 (#3961)
• Update org.xerial.snappy:snappy-java to version 1.1.10.8 (#3841)
