+
+## Linear issue automations
+
+- Added an `openedBy` filter so Linear issue automations only run for issues opened by specific users; defaults now include workspace members and the Tembo app actor.
+- Introduced a `temboIssues` toggle to safely opt into automations for Tembo-created Linear issues (off by default).
+- Expanded tests for Linear issue triggers and title formatting to keep the new filters reliable.
+
+## Model routing
+
+- Restored routing for `claude-opus-4-5` through Bedrock, keeping that model available for hosted runs.
+
+## UI polish
+
+- Sidebar stacked cards now fade in and recalculate height after sidebar changes, reducing layout jumps and keeping callouts readable.
