@@ -16,6 +16,7 @@ Docs: https://docs.openclaw.ai
 - Plugins/models: wire manifest `modelCatalog.aliases` and `modelCatalog.suppressions` into model-catalog planning and built-in model suppression, with stale Spark and Qwen Coding Plan suppressions now declared in plugin manifests instead of runtime fallback hooks. Thanks @shakkernerd.
 - Channels/Yuanbao: register the Tencent Yuanbao external channel plugin (`openclaw-plugin-yuanbao`) in the official channel catalog, contract suites, and community plugin docs, with a new `docs/channels/yuanbao.md` quick-start guide for WebSocket bot DMs and group chats. (#72756) Thanks @loongfay.
 - Channels/QQBot: add full group chat support (history tracking, @-mention gating, activation modes, per-group config, FIFO message queue with deliver debounce), C2C `stream_messages` streaming with a `StreamingController` lifecycle manager, unified `sendMedia` with chunked upload for large files, and refactor the engine into pipeline stages, focused outbound submodules, builtin slash-command modules, and explicit DI ports via `createEngineAdapters()`. (#70624) Thanks @cxyhhhhh.
+- Plugins/startup: migrate bundled plugin manifests to explicit `activation.onStartup` declarations so Gateway startup imports only the bundled plugins that intentionally register startup-time runtime surfaces. Thanks @shakkernerd.
 - Plugins/startup: add explicit `activation.onStartup` metadata so plugins can declare Gateway startup import behavior while the deprecated implicit sidecar fallback remains for legacy plugins. Thanks @shakkernerd.
 - Gateway/startup: reuse lookup-table plugin manifests when loading startup plugins so Gateway boot avoids rebuilding plugin discovery and manifest metadata. Thanks @shakkernerd.
 - CLI/models: declare fixed Qianfan, Xiaomi, NVIDIA, Cerebras, and Mistral model catalogs in plugin manifests so provider-filtered model listing can use the manifest fast path without loading provider runtime catalog code. Thanks @shakkernerd.
