 - Thinking defaults/status: raise the implicit default thinking level for reasoning-capable models from legacy `off`/`low` fallback behavior to a safe provider-supported `medium` equivalent when no explicit config default is set, preserve configured-model reasoning metadata when runtime catalog loading is empty, and make `/status` report the same resolved default as runtime.
 - Gateway/model pricing: fetch OpenRouter and LiteLLM pricing asynchronously at startup and extend catalog fetch timeouts to 30 seconds, reducing noisy timeout warnings during slow upstream responses.
+- Plugins/install: add newly installed plugin ids to an existing `plugins.allow` list before enabling them, so allowlisted configs load installed plugins after restart.
 - Status: show `Fast` in `/status` when fast mode is enabled, including config/default-derived fast mode, and omit it when disabled.
 - OpenAI/image generation: detect Azure OpenAI-style image endpoints, use Azure `api-key` auth plus deployment-scoped image URLs, and honor `AZURE_OPENAI_API_VERSION` so image generation and edits work against Azure-hosted OpenAI resources. (#70570) Thanks @zhanggpcsu.
 - Models/auth: merge provider-owned default-model additions from `openclaw models auth login` instead of replacing `agents.defaults.models`, so re-authenticating an OAuth provider such as OpenAI Codex no longer wipes other providers' aliases and per-model params. Migrations that must rename keys (Anthropic -> Claude CLI) opt in with `replaceDefaultModels`. Fixes #69414. (#70435) Thanks @neeravmakwana.

 `openclaw plugins update <id-or-npm-spec>` applies to tracked installs. Passing
 an npm package spec with a dist-tag or exact version resolves the package name
 back to the tracked plugin record and records the new spec for future updates.
