 - Web tools/Tavily: add Tavily as a bundled web-search provider with dedicated `tavily_search` and `tavily_extract` tools, using canonical plugin-owned config under `plugins.entries.tavily.config.webSearch.*`. (#49200) thanks @lakshyaag-tavily.
 - Docs/plugins: add the community DingTalk plugin listing to the docs catalog. (#29913) Thanks @sliverp.
 - Docs/plugins: add the community QQbot plugin listing to the docs catalog. (#29898) Thanks @sliverp.
+- Plugins/context engines: pass the embedded runner `modelId` into context-engine `assemble()` so plugins can adapt context formatting per model. (#47437) thanks @jscianna.
