 - Config/runtime snapshots: keep secrets-runtime-resolved config and auth-profile snapshots intact after config writes so follow-up reads still see file-backed secret values while picking up the persisted config update. (#37313) thanks @bbblending.
 - Gateway/Control UI: resolve bundled dashboard assets through symlinked global wrappers and auto-detected package roots, while keeping configured and custom roots on the strict hardlink boundary. (#40385) Thanks @LarytheLord.
 - Docs/Changelog: correct the contributor credit for the bundled Control UI global-install fix to @LarytheLord. (#40420) Thanks @velvet-shark.
+- Models/openai-codex GPT-5.4 forward-compat: use the GPT-5.4 1,050,000-token context window and 128,000 max tokens for `openai-codex/gpt-5.4` instead of inheriting stale legacy Codex limits in resolver fallbacks and model listing. (#37876) thanks @yuweuii.
