Sep 1, 2025In September 2025, canonical/mir delivered a set of cross-cutting improvements that enhance developer productivity, build reliability, and documentation readiness. Key templates and intake improvements streamline PR and issue workflows for bugs and features, reducing friction in code reviews. The Starter Pack was upgraded to 1.2.0 with accompanying file additions and cleanup, aligning new projects with current starter-pack conventions. Documentation tooling and API docs workflow were hardened with gating, improved doxygen/Sphinx integration, and ReadTheDocs alignment, improving build reliability and traceability of docs. CI and pre-commit hygiene were tightened and packaging references reorganized to support smoother releases. Finally, targeted bug fixes (spellcheck, woke checks, whitespace, and minor doc/comment fixes) improve correctness and readability, contributing to a more stable codebase and faster delivery.
