Nov 1, 2025November 2025 — microsoft/lisa: Focused feature delivery and test-harness improvements. Delivered Debian codename compatibility for the Performance Tool, enabling automated tests against both bookworm and trixie with zero manual configuration. No major bugs fixed this month; primary value came from expanding CI coverage and reducing test setup overhead. This work strengthens cross-distro testing fidelity and overall performance benchmarking reliability.

May 1, 2025May 2025: Environment Deletion Lifecycle Stabilization in microsoft/lisa. Fixed edge cases in environment deletion: retain environments marked as 'Bad' when keep_environment is enabled; set environment status to 'Deleted' only after cleanup attempts (regardless of success); and skip unnecessary deletion attempts in AzurePlatform when environment initialization fails. This reduces accidental deletions, stabilizes lifecycle semantics, and lowers cloud costs. Commit 665ee0446efceb1a89090d0eb6576a4286f8560d (Change/fix in the rg deletion condition).
