What’s new¶
Rockcraft 1.19 brings the following features, integrations, and improvements.
Support for ubuntu@26.04¶
Rockcraft now supports building rocks with the ubuntu@26.04 base, which is stable and recommended for all new rocks.
If you’re currently using ubuntu@24.04, you can migrate by following the Change from ubuntu@24.04 to ubuntu@26.04 guide.
If you were already building experimental ubuntu@26.04 rocks, you can drop
build-base: devel from your project file.
Stabilization of 12-factor app extensions¶
The extensions providing support for the 12-factor app methodology using Express, FastAPI
and Go are now stable and no longer require setting the
ROCKCRAFT_ENABLE_EXPERIMENTAL_EXTENSIONS environment variable.
Bazel plugin¶
The Bazel plugin supports building projects using the Bazel build system, and is available for rocks targeting bases ubuntu@25.10 and higher.
