2.10

🚀 Highlights

• Generated code is now verified to compile. Until now the test suite only
  compared the generated Java/Kotlin against text snapshots; it never checked
  that the output was valid, compilable code. A new in-process compilation
  harness now compiles every generated source as part of the tests — Java via
  the JDK compiler (javax.tools, with Lombok annotation processing) and Kotlin
  via kotlin-compiler-embeddable — guarding against generators that emit
  uncompilable code and making larger refactorings safer. (#511)

• The generated date (de)serializers are now exercised at runtime. The
  ZonedDateTime serializer/deserializer that the generator emits for
  date-time fields is compiled, loaded and round-tripped through Jackson in a
  functional test — including the offset-less fallback. (#511)

🐞 Bug fixes

• Kotlin: subclasses of a discriminated base type now compile. When a base
  schema declared a required property (e.g. a discriminated allOf hierarchy
  with a shared base property), the generated Kotlin subclasses called the base
  constructor with no arguments and failed to compile
  (No value passed for parameter '…'). Inherited base constructor properties
  are now re-declared as override val … and forwarded to the base
  constructor. Java output was already correct. (#512)

💼 Maintenance & dependencies

• Dependencies updates

Compatibility

• No breaking changes to the plugin configuration or generated API.
• Kotlin output for discriminated allOf hierarchies changes shape (subclasses
  now carry override val base properties); regenerate and recompile downstream
  Kotlin projects.
