Before: the blog had nothing on why format checks started failing on unchanged code during the
ubuntu-latest→ Ubuntu 26.04 rollout.After: a new Guides post explains it (the runner's default clang-format went from 18 to 21, and
clang-format-18isn't preinstalled on 26.04), shows four public projects that hit it, and gives three ways to pin the version (PyPI wheel, cpp-linter-actionversion, cpp-linter-hooks--version), plus how to upgrade on purpose.How: one new file,
docs/blog/posts/2026-11-09-ubuntu-26-04-clang-format.md, in the same front-matter format as the existing posts. Ubuntu package versions were checked on packages.ubuntu.com and the rollout dates on actions/runner-images#14748.mkdocs build --strictpasses locally.
