OpenAPI Generator
2.5DEVOPS
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.
Technitium DNS Server
5.0DEVOPS
Technitium adds LDAP sign-in to the DNS server that already gained SSO in v15.
◆ Current state
Technitium DNS Server has shipped eleven v15 releases since April, from v15.0 with OpenID Connect single sign-on to v15.6.2 on October 17. v15.5 in September added LDAP authentication and a zone file editor in the web console, and nearly every release since has carried fixes for reported security issues. Announcements are short and point to the CHANGELOG for detail.
◆ Where it's heading
The v15 line keeps extending admin identity, from OIDC to SSO scopes to LDAP, while patch releases arrive every one to two weeks with security fixes. That frequency of reported security issues is the thread to watch.
◆ Prediction
More v15.6.x service updates are likely; whether a v16 line follows is unclear from the feed.
