 ## Highlights
 
-- **Tool Registry Discovery:** Introduced tool registry discovery capabilities,
-  enabling automatic detection and registration of tools to improve
-  extensibility.
-- **Release Verification Improvements:** Enhanced release verification by
-  ignoring scripts during `npm ci` and preventing workspace binary shadowing.
-- **CI Pipeline Safeguards:** Strengthened the CI pipeline to prevent bad NPM
-  releases and ensure promote job failures are correctly surfaced.
+- **Caretaker Services on Cloud Run:** Implemented the foundational
+  infrastructure for Caretaker on Cloud Run, including a webhook ingestion
+  service and an egress service skeleton.
+- **Security Hardening & Sandbox Improvements:** Strengthened agent security by
+  enforcing case-insensitive checks on sensitive path blocklists, fixing
+  symbolic link directory escape vulnerabilities in memory imports, and making
+  user Git configuration read-only in the macOS sandbox.
+- **Model Interaction & Escape Sequences:** Resolved compatibility and parsing
+  issues for modern models by ensuring escape sequences are properly preserved
+  in string literals.
+- **Thought Leakage Mitigation:** Added safeguards to strip thoughts and
+  internal reasoning states from scrubbed conversational history turns,
+  preventing thought leakage.
+- **Robustness & Test Stability:** Improved overall stability by resolving
+  defensive pathing issues with at-reference files, updating Vertex base URLs,
+  and fixing proxy testing failures.
