v1.18.40 (September 4th, 2025)

• PLATFORM: JDK25 support added #3859.
• BUGFIX: Recent versions of eclipse (or the eclipse-based java lang server for VSCode) caused java.lang.IllegalArgumentException: Document does not match the AST. [Issue #3886](projectlombok/lombok#3886).
• PERFORMANCE: @ExtensionMethod is now significantly faster [Issue #3866](projectlombok/lombok#3866).
• BUGFIX: the command line config tool would emit incorrect output for nullity annotations. [Issue #3931](projectlombok/lombok#3931).
• FEATURE: @Jacksonized @Accessors(fluent=true) automatically creates the relevant annotations such that Jackson correctly identifies fluent accessors. [Issue #3265](projectlombok/lombok#3265), [Issue #3270](projectlombok/lombok#3270).
• IMPROBABLE BREAKING CHANGE: From versions 1.18.16 to 1.18.38, lombok automatically copies certain Jackson annotations (e.g., @JsonProperty) from fields to the corresponding accessors (getters/setters). However, it turned out to be harmful in certain situations. Thus, Lombok does not automatically copy those annotations any more. You can restore the old behavior using the config key lombok.copyJacksonAnnotationsToAccessors = true.
