March 2026 highlights for teemtee/tmt: delivered key quality and governance improvements across testing, release workflow, and project transparency. Fixed release workflow noise by instructing rpminspect to ignore Jinja XML templates during Fedora releases; documented testing framework tree semantics (user/work/test trees) and workdir usage to accelerate contributor onboarding; upgraded test reliability by migrating upgrade tests to a maintained dependency package and cleaning up cleanup hooks; added sprint-overview script to aggregate and display sprint issues/PRs, enabling better project management and Jira migration readiness. Together these efforts reduce false positives, improve testing stability, and strengthen release confidence.

February 2026 — Focused on stabilizing CI pipelines, delivering tooling enhancements, and tightening packaging stability to reduce install-time failures. Key features delivered include a TMT 1.67.0 release with improved export and plan adjustment capabilities and clearer command outputs; documentation improvements with guidance on parameterizing environment variables, a hardware provisioning example, and an expanded execution guide; Gemini Code Assist configuration to align behavior with developer needs; and code quality improvements introducing a Ruff check for unused imports. Test suite stabilization was pursued by running only the essential tests under the Podman “friends” plan to reduce flaky results. Major bug fixes included stabilizing the ELN container build/test pipeline (initial disable to unblock testing, followed by re-enabling once verification issues were resolved) and packaging stability improvements (pinning setuptools to avoid deprecated API usage and adding missing subpackages to tmt+all).
