What is Groonga?

Groonga is putting a full-text search engine into WebAssembly and the browser.

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

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.

5.0

Groonga is putting a full-text search engine into WebAssembly and the browser.

◆ Current state

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

◆ Where it's heading

The WebAssembly work is moving piece by piece from the core command to options and plugins, which points toward a usable in-browser search engine. Every WASI item is still marked experimental and not stable.

◆ Prediction

Expect more WASI coverage in the next 16.1.x releases, with the experimental label likely to stay for now.

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.
