May 2026 updates

May was an intense month on the maintenance front: two mass rebuilds — one for OCaml and one for GHC 9.14.1 — involved hundreds of packages. On the desktop side, KDE Plasma 6.6.5 and KDE Frameworks 6.26.0 further consolidate the stability of the graphical environment. Installation images are now generated systematically towards the end of the month, to always include the monthly KDE Plasma updates before publication.

OCaml and GHC mass rebuilds

During the month, two mass rebuilds were carried out for functional language libraries and tools:

• OCaml — rebuild of all dependent ocaml-* packages, including ocaml-ctypes, ocaml-luv, ocaml-posix, ocaml-srt and others. The rebuild ensures ABI consistency across the OCaml ecosystem.
• GHC 9.14.1 — the Haskell compiler was updated to version 9.14.1, triggering a rebuild of over one hundred ghc-* packages. The rebuild also produced an update to pandoc-cli 3.8.2, the universal document format conversion tool.

KDE Gear 26.04.1

Maintenance update for KDE applications: KDE Gear 26.04.1 brings bug fixes across the entire suite, including KDEConnect 26.04.1 (Android/iOS integration), Marble 26.04.1 (geographic maps) and the other applications in the suite.

KDE Plasma 6.6.5 and KDE Frameworks 6.26.0

KDE Plasma 6.6.5 updates all major desktop environment components with bug fixes and stability improvements. KDE Frameworks 6.26.0 updates the foundational libraries on which the entire KDE ecosystem is built.
