 ## Highlights
 
-- **Context Simplification:** Completed major architectural work to simplify and
-  optimize how the agent manages and processes session context.
-- **A2A Usage Metadata:** The Agent-to-Agent (A2A) interface now exposes
-  detailed usage metadata, providing better visibility into resource
-  consumption.
-- **Improved Routing:** Updated default auto-routing logic and added bypasses
-  for certain routing classifiers to prevent orphaned function response errors.
-- **Terminal Stability:** Fixed several issues affecting terminal environments,
-  including Termux relaunch loops and PTY resize errors.
-- **Security & Fixes:** Strengthened MCP list security and addressed issues with
-  session resumption and PTY environment signals.
+- **Model Update:** Added support for transitioning to the Flash GA model when
+  the experimental flag is enabled, providing access to the latest model
+  improvements.
+- **Improved Stability:** Hardened PTY resize logic to prevent native crashes,
+  ensuring a more robust terminal experience.
+- **Bug Fix:** Resolved an issue where an invalid `preferredEditor`
+  configuration could lead to a notification spam loop.
+- **CI Enhancements:** Optimized Pull Request labeling and introduced batch
+  workflows to improve development efficiency.
