> Release Notes
> -------------
>
> This minor release introduces bug fixes, behavior improvements, and
> complete support for GraalVM native image generation.
>
> GraalVM Reachability Metadata
> -----------------------------
>
> Log4j Core and all extension modules now include embedded GraalVM
> reachability metadata [1], enabling seamless generation of native
> images with GraalVM out of the box—no manual configuration required.
> For more information, refer to our GraalVM guide [2].
>
> Note:
>
> When building third-party Log4j plugins, using the new
> `GraalVmProcessor` introduced in version `2.25.0` will automatically
> generate the required reachability metadata for GraalVM native images.
> However, the processor will fail the build if the required
> `log4j.graalvm.groupId` and `log4j.graalvm.artifactId` parameters are
> not provided. For detailed instructions, see Registering plugins [3].
>
> Exception Handling in Pattern Layout
> ------------------------------------
>
> Exception handling in Pattern Layout [4] has undergone a significant
> rewrite. This update resolves several bugs and ensures consistent
> behavior across all exception converters. Key improvements include:
>
> * Stack traces are now consistently prefixed with a newline.
> * The default exception converter has changed from extended [5] to
> plain [6], offering better performance.
> * Support for the `{ansi}` option in exception converters has been
> removed.
>
> Date & Time Formatting
> ----------------------
>
> Log4j has historically provided custom date and time formatters for
> performance, such as FixedDateFormat [7] and FastDateFormat [8]. These
> are now deprecated in favor of Java’s standard DateTimeFormatter [9].
>
> If you encounter formatting issues after upgrading—particularly with `n`
> or `x` directives—you can temporarily revert to the legacy formatters by
> setting the `log4j2.instantFormatter` property to `legacy` [10]. Please
> report any issues via our issue tracker [11].
>
> ANSI Support on Windows
> ------------------------
>
> Modern Windows versions (10 and newer) provide native ANSI escape
> sequence support. As a result, dependency on the outdated JAnsi 1.x
> library has been removed. For details, refer to ANSI styling on Windows
