Free SQL Server and PostgreSQL performance monitoring: headless collector service, desktop apps, MCP server, and web dashboard. No agents, no per-core pricing.
Highlights:
- Fleet-card correctness: a card no longer reports a metric "Healthy" when nothing measured it, and PostgreSQL targets now read instance CPU where a source exists (#3267, #3271, #3272).
- Azure SQL Database: master-connected size collection no longer fails on a sibling-row null (#3262), and the Agent surface reports as not-applicable rather than "msdb access: yes" (#3237).
- PostgreSQL: absent optional extensions report EXTENSION_MISSING with a real remedy instead of a phantom permissions failure (#3240), the pg_read_file grant guidance is corrected (#3239), and the first-target runbook and README are re-derived from the shipped product (#3247, #3261).
- Zero-warning build cleanup (#3241) plus the rest of the pre-release fix wave.
