 ## Unreleased
 
+### Changes
+
+- Sandbox: add `sandbox.browser.binds` to configure browser-container bind mounts separately from exec containers. (#16230) Thanks @seheepeak.
+
 ### Fixes
 
 - macOS: hard-limit unkeyed `openclaw://agent` deep links and ignore `deliver` / `to` / `channel` unless a valid unattended key is provided. Thanks @Cillian-Collins.
