Dasha 1.10 adds Patroni auto-discovery and wait analysis for PostgreSQL fleets
Dasha 1.10 introduces Patroni auto-discovery via etcd v3 or Consul, automatically turning each Patroni scope into a monitored cluster with members as hosts and databases listed from PostgreSQL. New clusters, lost replicas, and database changes appear within the refresh interval. The tool reads DCS keys without writing, supports per-scope credential overrides and TLS with client certificates. Standby clusters now show their replication source and primaries display standbys on Summary and Replication pages, matched by PostgreSQL system identifier. Activity and Waits charts for PostgreSQL 14+ provide live visualization of active sessions.
Why it matters: This release reduces operational overhead for teams managing PostgreSQL fleets by eliminating manual cluster registration and providing real-time topology awareness across primary-standby setups. Combined wait analysis and replication slot forecasting help identify performance bottlenecks and replication lag before they impact applications. The read-only, agentless design minimizes security surface while supporting TLS and per-scope credentials for compliance.

Linux 7.4-rc2 released as mainline kernel update
Linux kernel version 7.4-rc2 was released on November 9, 2026, as a mainline update. The release candidate is available as linux-7.4-rc2.tar.gz with a full incremental patch. This marks the second release candidate in the 7.4 development cycle, following the standard kernel development process where release candidates are issued weekly for testing before the final stable release.
Why it matters: Release candidates allow developers and system maintainers to test upcoming kernel changes before production deployment. The incremental patch format enables efficient updates from previous release candidates. As a mainline kernel, 7.4-rc2 includes new features, driver support, and fixes that will eventually reach stable distributions, making early testing valuable for hardware compatibility and regression detection.
