@@ -19,6 +19,7 @@ Docs: https://docs.openclaw.ai
 - TUI/dependencies: remove direct `cli-highlight` usage from the OpenClaw TUI code-block renderer, keeping themed code coloring without the extra root dependency. Thanks @vincentkoc.
 - Diagnostics/OTEL: export run, model-call, and tool-execution diagnostic lifecycle events as OTEL spans without retaining live span state. Thanks @vincentkoc.
 - Providers/Anthropic Vertex: move the Vertex SDK runtime behind the bundled provider plugin so core no longer owns that provider-specific dependency. Thanks @vincentkoc.
+- Plugins/web fetch: move local Readability extraction into a bundled plugin so core no longer owns the Readability and DOM parser dependencies. Thanks @vincentkoc.
 - Plugins/activation: expose activation plan reasons and a richer plan API so callers can inspect why a plugin was selected while preserving existing id-list activation behavior. (#70943) Thanks @vincentkoc.
 - Plugins/source metadata: expose normalized install-source facts on provider and channel catalogs so onboarding can explain npm pinning, integrity state, and local availability before runtime loads. (#70951) Thanks @vincentkoc.
 - Plugins/catalog: pin the official external WeCom channel source to an exact npm release plus dist integrity, with a guard that official external sources stay integrity-pinned. (#70997) Thanks @vincentkoc.
