 - 🔐 **Channel sharing permission enforcement.** Channel creation and updates now enforce allowed access grant rules for public sharing, preventing unauthorized wildcard sharing on group channels. [#23638](https://github.com/open-webui/open-webui/pull/23638)
 - 🛑 **Socket role invalidation.** Socket sessions now disconnect automatically when a user is demoted or deleted, preventing stale admin privileges from persisting until reconnect. [#23642](https://github.com/open-webui/open-webui/pull/23642)
 - 🛂 **Tool server access checks.** Tool listing now correctly awaits server access checks, preventing users from seeing server-backed tools they do not have permission to use. [Commit](https://github.com/open-webui/open-webui/commit/d40f31982be3eed37e55e3f67b1eea9a5dc8c525)
+- 🧩 **Tool enum value handling.** Tool schema generation now safely handles enum values as strings, preventing failures when OpenAPI parameters include non-string enum entries. [#23597](https://github.com/open-webui/open-webui/issues/23597), [Commit](https://github.com/open-webui/open-webui/commit/4498e6faf2b1bdd1caa0e2c1c15d90a2790cd721)
 - 🧷 **Responses model access control.** The OpenAI-compatible Responses endpoint now enforces per-model permissions, preventing non-admin users from accessing models they are not allowed to use. [#23481](https://github.com/open-webui/open-webui/pull/23481)
 - 🚫 **Inactive member channel access.** Deactivated group members can no longer read or write channel content through direct API calls, so channel permissions now match active membership status. [#23623](https://github.com/open-webui/open-webui/pull/23623)
 - 🎛️ **Ollama endpoint model permissions.** Restricted models are now protected on Ollama show, generate, embed, and embeddings endpoints, preventing authenticated users from using private models without read access. [#23631](https://github.com/open-webui/open-webui/pull/23631)
