Nov 1, 2025November 2025 — Focused on stabilizing the build for the p4c project by isolating flaky external dependencies. Key action: temporarily disable the p4lang-bmv2 Debian package to preserve build stability while issues are addressed. This prevented unstable builds and allowed continued progress on core development. No new user-facing features were released this month; stabilization and risk mitigation were the priority. All changes were reviewed and signed off appropriately.
