Release Notes

google/error-prone (com.google.errorprone:error_prone_annotations)

### [`v2.28.0`](https://togithub.com/google/error-prone/releases/tag/v2.28.0): Error Prone 2.28.0 Error Prone nows supports the latest JDK 23 EA builds ([#​4412](https://togithub.com/google/error-prone/issues/4412), [#​4415](https://togithub.com/google/error-prone/issues/4415)). Closed issues: - Improved errors for invalid check severities ([#​4306](https://togithub.com/google/error-prone/issues/4306)). - Fix a crash with nested `instanceof` patterns ([#​4349](https://togithub.com/google/error-prone/issues/4349)). - Fix a crash in JUnitIncompatibleType ([#​4377](https://togithub.com/google/error-prone/issues/4377)). - In ObjectEqualsForPrimitives, don't suggest replacing `equal` with `==` for floating-point values ([#​4392](https://togithub.com/google/error-prone/issues/4392)). New checks: - [`DeeplyNested`](https://errorprone.info/bugpattern/DeeplyNested) discourages very deeply nested code that can cause StackOverflowErrors during compilation. - [`GuiceNestedCombine`](https://errorprone.info/bugpattern/GuiceNestedCombine) discourages nesting of `Modules.combine()`, which is unnecessary. - [`PatternMatchingInstanceof`](https://errorprone.info/bugpattern/PatternMatchingInstanceof) migrates code to use [pattern matching for `instanceof`](https://openjdk.org/jeps/394) - [`SunApi`](https://errorprone.info/bugpattern/SunApi) discourages use of internal proprietary JDK APIs which may be removed from future releases.
