 ## Highlights

- **Unified Auto Mode:** Merged all "Auto" modes into a single, unified Auto
-  mode, simplifying the automation workflow and providing a more consistent
-  experience across tasks.
- **Expanded Editor Support:** Native support for Sublime Text and Emacs Client
-  has been added, giving developers more flexibility in their choice of external
-  editors.
- **TUI Automation Skills:** New `agent-tui` and `tui-tester` skills enable the
-  programmatic testing and automation of terminal UI (TUI) applications,
-  facilitating robust verification of terminal-based tools.
- **Improved UI Performance:** Throttled shell text output and added bounds to
-  the live UI buffer to ensure smooth rendering and stability during high-volume
-  output sessions.
- **Stabilized Sandbox Environments:** Explicitly clearing entrypoints when
-  spawning sandbox containers ensures reliable and consistent environment
-  initialization across different Linux distributions.
+- **Context Manager Simplification:** Completed a significant refactoring of the
+  context management system to improve reliability and architectural clarity.
+- **A2A Usage Metadata:** Enhanced the Agent-to-Agent protocol to expose usage
+  metadata, enabling more transparent resource monitoring.
+- **Terminal & PTY Robustness:** Resolved several critical issues related to
+  terminal interactions, including Termux relaunch loops and PTY resize errors.
+- **Routing Optimizations:** Updated default auto-routing and bypassed
+  classifiers for specific tool responses to prevent orphaned function errors.
+- **Tool Execution Control:** Forced the `update_topic` tool to execute
+  sequentially, ensuring consistent narrative flow in agent interactions.

 ## 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.
