End of Life Announcement: Debian 11
On the 31st of August of this year (2026) Debian 11 "Bullseye" reached the end of its Long Term Support period, at which point we consider Bullseye to be End of Life. As we do not want to support our software running in unpatched environments, we have stopped building for Debian Bullseye. After the 1st of January 2027, we will start removing all repositories for this unsupported distribution from https://repo.powerdns.com/ . Users are recommended to upgrade their systems to supported operating system versions, such as Debian 12 or 13, or RHEL 9, 10, or any of the popular derivatives of RHEL.

A More Reliable Compilation Scheme for Kotlin Multiplatform Modules
The current compilation approach to Kotlin Multiplatform projects works, but sometimes can lead to unexpected or hard-to-predict behavior. For example: With Kotlin 2.5.0-Beta1, we introduced an optional “separate compilation” approach to KMP that solves both problems: make the compilation results consistent with IDE analysis, and point more consistently to problematic calls of library code from […]
8.12-m02-int: Explain a test [TIMEOUT] instead of killing it silently (#15879)
A hung test run tells us almost nothing today. When no client has made progress for --timeout seconds, test_server_cron prints the clients' last reported state, SIGKILLs every server via force_kill_all_servers and exits; --dump-logs only fires for a failed or excepted test, never for a timeout. So a 20-minute hang costs a whole CI run and produces a few lines. Collect the evidence before tearing the run down: Crash-report the surviving servers. SIGSEGV makes redis log a stack trace of every one of its threads plus INFO, the client list and the config (printCrashReport) and then die. The handl…
