 # @shopify/ucp-cli
 
+## 0.9.0
+
+### Minor Changes
+
+- cb59279: `ucp-cli` now negotiates the newest exact UCP release shared with each Business, using the managed Profile by default. This build supports **2026-04-08** and **2026-08-25**; extension-key validation follows the selected release.
+
+  Untouched Profiles generated by earlier releases continue working as named managed Profiles. Edited or custom-hosted Profiles retain their authored document and URL. `ucp profile init` remains available for intentional customization or release pinning, accepts one exact `--version`, and activates only with `--activate`; the former range flags and inert `profile publish` command are removed.
+
+  Other observable changes:
+
+  - `ucp discover` reports the selected protocol and services declared by both Profiles.
+  - MCP mode ignores Profile and Business selections in `active.yaml`; explicit arguments and environment variables still apply.
+  - Business discovery and `tools/list` are cached separately between runs. `--refresh` bypasses both caches; `--dry-run` skips only the operation call.
+  - Doctor enforces the Node.js `22.19.0` runtime floor, exits nonzero on failed checks, and separately reports Profile redirects, drift, and cache policy.
+  - UCP document and declared endpoint redirects raise `TRANSPORT_REDIRECT_REFUSED` rather than being followed.
+  - Profile, version, and service failures now distinguish Profile-side and Business-side causes; see the error-code reference for recovery.
+  - `ucp checkout complete` now accepts and sends its required completion body like other write operations.
+
 ## 0.8.0
