What is OpenAPI Generator?

OpenAPI Generator keeps a 240-change release cadence across dozens of languages

OpenAPI Generator ships stable releases every few weeks to two months, each with 150 to 240 changes across generators for C#, C++, Go, Java, Kotlin, Dart and many more. 7.26.0 fixes nullable allOf handling in OpenAPI 3.1, exposes schema tracking in the Gradle plugin, adds .NET 10 support for aspnetcore and a Boost.Beast HTTP/1.1 server generator for C++. 7.25.0 before it added vendor override injection and splitOperationsByContentType.

What is Postgres Operator?

Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.

Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.

OpenAPI Generator vs Postgres Operator: editorial side-by-side

O2.5

OpenAPI Generator keeps a 240-change release cadence across dozens of languages

◆ Current state

OpenAPI Generator ships stable releases every few weeks to two months, each with 150 to 240 changes across generators for C#, C++, Go, Java, Kotlin, Dart and many more. 7.26.0 fixes nullable allOf handling in OpenAPI 3.1, exposes schema tracking in the Gradle plugin, adds .NET 10 support for aspnetcore and a Boost.Beast HTTP/1.1 server generator for C++. 7.25.0 before it added vendor override injection and splitOperationsByContentType.

◆ Where it's heading

The core keeps absorbing OpenAPI 3.1 semantics while each language generator takes fixes from its own maintainers. New generators and framework versions arrive steadily, and breaking changes ship with fallbacks.

◆ Prediction

OpenAPI 3.1 normalisation fixes have appeared in every recent release, so expect them in the next one too.

P0.0

Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.

◆ Current state

Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.

◆ Where it's heading

The v2 line is still in stabilization, with each patch carrying a breaking change of some kind. The AWS and IRSA fixes suggest EKS users are the main early adopters.

◆ Prediction

Expect further 2.0.x patches on a roughly six-week cycle; a 2.1 feature release is not visible in the entries.
