 ## Highlights
 
-- **GDC Service Identity Support**: Added support for GDC air-gapped Service
-  Identity after a major auth library update.
-- **Standardised Tool Outputs**: Standardised tool output formatting to ensure
-  consistency and readability across different CLI commands.
-- **Static Evaluation Analyzer**: Introduced a new static evaluation source
-  analyzer to improve development and testing.
-- **Vulnerability Prevention**: Hardened CLI security by preventing path
-  traversal vulnerabilities during the installation of Skills.
-- **Configuration & Error Hardening**: Migrated the `coreTools` configuration
-  setting to `tools.core` and ensured zero-quota limits fail fast to prevent
-  infinite retry loops.
+- **Caretaker Cloud Run Services**: Implemented a Cloud Run webhook ingestion
+  service and egress service skeleton to support advanced caretaker features.
+- **Enhanced Security & Sandbox Hardening**: Enforced a case-insensitive
+  sensitive path blocklist and VS Code human-in-the-loop (HITL) checks, resolved
+  a directory escape vulnerability in the memory import processor, and marked
+  `~/.gitconfig` as read-only within the macOS sandbox.
+- **Improved Thought Leakage and Escape Handling**: Resolved potential thought
+  leakage by stripping thinking/thought processes from scrubbed history turns,
+  and ensured escape sequences in string literals are correctly preserved for
+  modern models.
+- **Robust Path & API Updates**: Enhanced defensive path resolution for
+  at-reference files, and updated the Vertex AI base URL configuration to
+  support the latest API updates.
