🎉 Guider 3.9.9: First Major Release in 5 Years!

We’re proud to announce Guider 3.9.9, a long-awaited release with over
4,000 commits and 182 powerful commands now available!

Guider is more than a performance monitoring tool — it's a platform-level
performance diagnostics and monitoring service. It offers always-on
monitoring, real-time diagnostics, visual analytics, and command-based APIs
that apps and backends can directly integrate over TCP/UDS.
