About OpenAPI Generator
OpenAPI Generator holds a 240-change cadence across forty-odd language targets.
The project ships stable releases every four to eight weeks, each carrying 150 to 240 enhancements and fixes spread across generators for C#, Dart, Go, Java, Kotlin, C++, Crystal and dozens more. 7.25.0 follows the pattern: a parser update, restored schemaMapping imports in API interfaces, a stable input-spec hash for the Maven plugin, a way for clients to inject vendor overrides, and splitOperationsByContentType. Every recent release is labelled as carrying breaking changes with fallbacks.
