# Sidekick RELEASE.2025-10-16T22-34-38Z

Released: 2025-10-16

This release focuses on improving multi-site reliability and health check efficiency. Key improvements include fixing a critical race condition in multi-site connection statistics tracking and adding randomized jitter to health checks to prevent resource contention during startup.

## Bug Fixes

- **Fixed race condition in multi-site connection statistics tracking (#15)** - Resolved critical issue where `globalConnStats` only tracked statistics for the last site in multi-site configurations. The statistics are now properly maintained for all configured sites, ensuring accurate metrics and load balancing decisions across the entire deployment. Multi-site users should upgrade to ensure proper backend selection and monitoring.

## Improvements

- **Added jitter to initial health checks to prevent thundering herd (#14)** - Health checks now include randomized jitter during initialization to prevent simultaneous connection attempts to backend servers. This distributes the load more evenly during sidekick startup or configuration reloads, reducing resource contention and improving startup reliability in large deployments.
