Sourced from org.projectlombok:lombok's changelog.

v1.18.46 (April 22nd, 2026)

• PLATFORM: JDK26 support added #4019.
• PLATFORM: Spring Tools Suite 5 supported #3985.
• BUGFIX: @Jacksonized no longer stops generating @JsonProperty once an explicit @JsonIgnore annotations is encountered #4022.
• BUGFIX: In eclipse, mixing @Jacksonized and fluent = true no longer causes the error com.fasterxml.jackson.annotation.JsonProperty is not a repeatable annotation interface. #3934.
• BUGFIX: Some finishing touches for v1.18.44's support of Jackson3 #4004.

v1.18.44 (March 11th, 2026)

• FEATURE: @Jacksonized now supports both Jackson2 and Jackson3; you'll get a warning until you configure which one (or even both!) you want lombok to generate. #3950.
• BUGFIX: On JDK25, val and @ExtensionMethod could sometimes cause erroneous errors (in that you see errors but compilation succeeds anyway) using javac. #3947.
• BUGFIX: @Jacksonized + fields marked transient would result in those transient fields being serialised which is surprising (and thus undesired) behaviour. #3936.

v1.18.42 (September 18th, 2025)

• FEATURE: All the various @Log annotations now allow you to change their access level (they still default to private). #2280. Thanks to new contributor Liam Pace!
• BUGFIX: Javadoc parsing was broken in Netbeans and ErrorProne for JDK25 #3940.

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.
