 ## Release Notes
 
+The `1.5.0` release relicenses Nexus Unity under MIT and hardens the public local-automation surface: every HTTP/WebSocket request now requires the session token; script writes and bulk PlayerPrefs deletion have explicit confirmation gates; raw batches are bounded; and readiness reports are safe during import and Play Mode transitions. It also improves cheap GameObject read-back, primitive validation, bridge resources, current MCP client setup, path-security coverage, test-result reporting, and cross-platform CLI launch reliability. See the complete, migration-relevant detail in the `1.5.0` changelog entry.
+
 The `1.4.2` patch removes direct Unity Project Auditor dependencies to avoid clean-install Console spam, keeps Nexus lint checks available without Project Auditor rules, and tightens the Python MCP bridge schemas, routing types, and compile/test polling behavior.
 
 The `1.4.1` patch adds the missing package folder `.meta` files (`docs/`, `docs/assets/`, `Editor/tests/`) so fresh installs no longer log "no meta file" warnings, and hardens the pre-push `.meta` validation to check the git-tracked tree and every folder.
