• BREAKING CHANGE: mapstruct users should now add a dependency to lombok-mapstruct-binding. This solves compiling modules with lombok (and mapstruct).
• IMPROBABLE BREAKING CHANGE: The generated hashcode has changed for classes that include both primitive fields and reference fields.
• FEATURE: Similar to @Builder, you can now configure a @SuperBuilder's 'setter' prefixes via @SuperBuilder(setterPrefix = "set") for example. We still discourage doing this. Pull Request #2357.
• FEATURE: If using @Synchronized("lockVar"), if lockVar is referring to a static field, the code lombok generates no longer causes a warning about accessing a static entity incorrectly.
• FEATURE: @Jacksonized on a @Builder or @SuperBuilder will configure Jackson to use this builder when deserializing. Pull Request #2387 thanks to @JanRieke. @Jacksonized documentation.
• FEATURE: The checkerframework support has been updated; the relevant annotations were renamed in checkerframework's APIs, lombok now generates the annotations according to their current API names.
• PLATFORM: Added support for compiling projects with OpenJ9 Pull Request #2437
• PLATFORM: Improved support for recent JVM/javac versions (14 and 15) and new language features.
• PERFORMANCE: Several performance improvements during parsing/compilation, both using javac and Eclipse. Thanks @Rawi01!
• PERFORMANCE: The generated equals method will first compare primitives, then primitive wrappers and then reference fields. Manual re-ordering is possible using @Include(rank=n). Pull Request #2485,
• BUGFIX: Delombok prints the first this parameter.
• BUGFIX: Using val in combination with values whose generics include wildcards that reference themselves would cause a StackOverflowError in javac. .
• BUGFIX: Using @SuperBuilder on a class that has some fairly convoluted generics usage would fail with 'Wrong number of type arguments'. Pull Request #2362
• BUGFIX: Various lombok annotations on classes nested inside enums or interfaces would cause errors in eclipse.
• BUGFIX: Trying to add @ExtensionMethods with exactly 2 arguments would fail in eclipse. Pull Request #2376 thanks to @Rawi01.
• BUGFIX: Javac sets incorrect annotated type on with methods.
