• Enhanced health checks - Check database and eRPC capabilities during health check operations (#691)
• More consistency with postgres on auth errors - Improves errors in some client libraries (#711)

Performance Improvements

• Optimized ranch usage - Supavisor now uses a constant number of ranch instances for improved performance and resource management when hosting a large number of pools (#706)

Monitoring

• New OS memory metrics - gives a more accurate picture of memory usage (#704)
• Add a promex plugin for cluster metrics - for tracking latency and connection status (#690)
• Client connection lifetime metrics - adds a metric about how long each connection is connected for (#688)
• Process monitoring - Log when large process heaps and long message queues (#689)

Bug Fixes

• Client handler query cancellation - Fixed handling of :cancel_query when state is :idle (#692)

Migration Notes

• Instances running a small number of pools may see an increase in memory usage. This can be mitigated by changing the ranch shard or the acceptor counts.
• If using any of the new used ports, may need to change the defaults
• Review monitoring dashboards and include new metrics
