April 2025 — canonical/testflinger: Delivered revision-based charm deployment control in Terraform, enabling explicit charm version pinning. Introduced a revision variable that takes precedence over channel to allow granular, reproducible deployments. Updated environment variable validation to include 'production' and to gracefully handle null revisions, reducing production misconfigurations. Commits: 723d9f58e9d1313d49fe14634fd4934a50868692 (#494). Impact: improved deployment precision, safer production operations, and stronger IaC discipline with easier rollbacks through explicit revision control. Technologies/skills demonstrated: Terraform, environment validation, IaC best practices, version-controlled deployments, channel/revision precedence logic.
