What's Changed

New Features

• Support openapi-generator-maven-plugin Version 7.15.0 by @Chrimle in #505

  Official support for Version 7.15.0 of openapi-generator-maven-plugin. From now on, all changes will also be tested with 7.15.0.

• Support openapi-generator-maven-plugin Version 7.16.0 by @Chrimle in #509

  Official support for version 7.16.0 of openapi-generator-maven-plugin. NOTE: this dependency update will add import java.util.Locale; to ALL generated record/enum classes.

• Support openapi-generator-maven-plugin Version 7.17.0 by @Chrimle in #510

  Official support for version 7.17.0 of openapi-generator-maven-plugin. This version will also be used during tests. This update does not update generated record/enum classes.

Bug Fixes

• Remove Extra Indentation on record-fields by @Chrimle in #515

  Removes an extra indentation (space) before each field of a record-class. This is to conform to google-java-format. NOTE: This affects ALL generated record classes. This is only a formatting fix, and does not not affect functionality in any way.

• Avoid Instantiating Unused Fallback List/Set-instances by @Chrimle in #518

  Fixes an unintended implementation of fallback values for records with List/Set-fields. A fallback instance (ArrayList / LinkedHashSet) would always be instantiated, despite never being used, due to the usage of Objects.requireNonNullElse(T,T). The fix is to use Objects.requireNonNullElseGet(T,() -> T) for List/Set-fields. This ensures that these fallback/default objects are not instantiated unless needed. No changes have been made to other field types. NOTE: This is intended as a performance improvement, and should not affect functionality.

Summary & Reflection

This release adds official support for newer versions of openapi-generator-maven-plugin, which means that the .mustache template files are compatible with even more versions - verified by the extensive test suite. An implementation bug was discovered in record classes that have List/Set-fields, which was quickly fixed. Similarly, indentations of all fields in record classes were incorrect, but addressed quickly. This is the first MINOR release since 3.0.0, and is also intended as a production-ready release. With that said, a poll has been opened about creating/publishing release candidates. See #520, to better catch issues and potentially establish a more stable/predictable release cadence.
