 ### v1.18.24 "Edgy Guinea Pig"
 * FEATURE: Turning a field named `uShape` into a getter is tricky: `getUShape` or `getuShape`? The community is split on which style to use. Lombok does `getUShape`, but if you prefer the `getuShape` style, add to `lombok.config`: `lombok.accessors.capitalization = beanspec`. [Issue #2693](https://github.com/projectlombok/lombok/issues/2693) [Pull Request #2996](https://github.com/projectlombok/lombok/pull/2996). Thanks __@YonathanSherwin__!
 * BUGFIX: Various save actions and refactor scripts in eclipse work better. [Issue #2995](https://github.com/projectlombok/lombok/issues/2995) [Issue #1309](https://github.com/projectlombok/lombok/issues/1309) [Issue #2985](https://github.com/projectlombok/lombok/issues/2985) [Issue #2509](https://github.com/projectlombok/lombok/issues/2509)
+* NOTE: A widely reported security issue with log4j2 ([CVE-2021-44228](https://www.randori.com/blog/cve-2021-44228/)) has absolutely no effect on either lombok itself nor does usage of lombok on its own, or even the usage of lombok's `@Log4j2`, cause any issues whatsoever: You have to ship your own log4j2 dependency in your app - update that to 2.15 or otherwise mitigate this issue (see the CVE page). To avoid unneccessary warnings from dependency checkers, our dep on log4j2, which is used solely for testing and cannot be exploited in any way, has been updated to 2.15.0. [Issue #3063](https://github.com/projectlombok/lombok/issues/3063)
 
 ### v1.18.22 (October 6th, 2021)
 * PLATFORM: JDK17 support added. [Issue #2898](https://github.com/projectlombok/lombok/issues/2898).
