 # Changelog
 
+## 2026-03-27 - 11.12.1 - fix(dcrouter)
+retry auto certificate provisioning after SmartAcme becomes ready
+
+- detects certificates that failed during startup before the DNS-01 provider was available
+- clears provisioning backoff and failed status for affected domains before retrying
+- re-triggers auto certificate provisioning for SmartProxy routes once SmartAcme is ready
+
+## 2026-03-27 - 11.12.0 - feat(web-ui)
+pause dashboard polling, sockets, and chart updates when the tab is hidden
+
+- replace interval-based auto-refresh with scheduled actions using visibility-aware auto-pause
+- disconnect and reconnect the TypedSocket on tab visibility changes to avoid background log buildup
+- batch pushed log entries per animation frame and add an in-flight refresh guard to reduce unnecessary re-renders and overlapping requests
+- update state subscriptions to use select() and document the new tab visibility optimization behavior
+- bump smartdb, smartproxy, smartstate, remoteingress, dees-element, and tstest dependencies
+
 ## 2026-03-26 - 11.11.0 - feat(docker,cache,proxy)
 improve container runtime defaults and add configurable connection limits
