 ## 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.
+- **Antigravity Agent & PR Generator:** Integrated the Antigravity agent runner,
+  Firestore dual-locking for concurrency, prompt templates, and ingestion
+  testing utilities.
+- **Caretaker Triage & Issue Management:** Enhanced the issue triage workflow by
+  automatically posting a comment before closing issues, and sanitizing and
+  wrapping issue titles in `untrusted_context`.
+- **Core API & Session Stability:** Enforced HTTPS for
+  GoogleCredentialsAuthProvider to prevent cleartext leakage, rotated session
+  IDs on model fallback to prevent stateful API errors, and refined chat history
+  by filtering out thought parts when context management is disabled.
