+## v1.21.0 - 2026-06-26
+### Enhancement or New Feature
+* Track MCP client identity (name and version from the MCP initialize handshake) in Vortex tool call events via the user_agent field
+### Under the Hood
+* Revert host elicitation (pre-v1.17.0 behaviour where DBT_HOST=None)
+* Add a CI check that snapshots the published-app contract (tool metadata, schemas, annotations, server instructions, UI resources) and fails when it changes, plus a workflow that labels contract-changing PRs
+### Bug Fix
+* Fix list_saved_queries tool which was calling savedQueriesPaginated (a non-existent API field) instead of savedQueries
+* Preserve unique_id casing when querying the Discovery API — the uniqueIds filter is case-sensitive, so lowercasing caused empty results for models with uppercase names
