@@ -32,6 +32,7 @@ Docs: https://docs.openclaw.ai
 - secrets: harden read-only SecretRef command paths and diagnostics. (#47794) Thanks @joshavant.
 - Browser/existing-session: support `browser.profiles.<name>.userDataDir` so Chrome DevTools MCP can attach to Brave, Edge, and other Chromium-based browsers through their own user data directories. (#48170) Thanks @velvet-shark.
 - Skills/prompt budget: preserve all registered skills via a compact catalog fallback before dropping entries when the full prompt format exceeds `maxSkillsPromptChars`. (#47553) Thanks @snese.
+- Models/OpenAI: add native forward-compat support for `gpt-5.4-mini` and `gpt-5.4-nano` in the OpenAI provider catalog, runtime resolution, and reasoning capability gates. Thanks @vincentkoc.
 - Plugins/bundles: make enabled bundle MCP servers expose runnable tools in embedded Pi, and default relative bundle MCP launches to the bundle root so marketplace bundles like Context7 work through Pi instead of stopping at config import.
 - Scope message SecretRef resolution and harden doctor/status paths. (#48728) Thanks @joshavant.
 - Plugins/testing: add a public `openclaw/plugin-sdk/testing` seam for plugin-author test helpers, and move bundled-extension-only test bridges out of `extensions/` into private repo test helpers.
