Apr 1, 2026April 2026 monthly summary for yugabyte/yugabyte-db focusing on stability and provisioning reliability. Key accomplishments include stabilizing the full move operation when the number of attached volumes changes by ensuring the updated userIntent is passed to the YNP subtask during the edit operation. The change is tied to PLAT-20134 and includes an end-to-end test plan: create universe, edit number of volumes, verify success. Code was reviewed by nsingh and anijhawan; differential revision D51998. This work improves provisioning reliability, reduces upgrade risk, and enhances operator experience.

Feb 1, 2026February 2026: Achieved safety, reliability, and flexibility gains in yugabyte-db. Implemented safety checks for node removal and prechecks (AreNodesSafeToTakeDown) to prevent RF3 deadlocks, added Precheck-only flow to release reserved onprem nodes, introduced a Not Preferred option for leader placement to broaden strategy options, fixed Grafana CPU seconds metric calculations, and corrected ARM architecture identification in the earlyoom installer. Also addressed ARM/packaging and test stability in related commits. These changes reduce operational risk, improve deployment resilience, and enhance observability with sbt-based tests and code-review driven quality.
