What's Changed

✨ New

• Added react-web-api/no-leaked-intersection-observer rule to prevent leaked IntersectionObserver instances in components and hooks, enabled as warn in the recommended preset (#1841, #1868).

🐞 Fixes

• react-web-api/no-leaked-intersection-observer, react-web-api/no-leaked-resize-observer: Report when disconnect is only called inside the observer's own callback, since the callback may never run if the component unmounts before the element intersects or resizes (#1872).

🏗️ Internal

• Improved CI configuration and updated SECURITY.md documentation (#1871).
• Bumped fumadocs-core and fumadocs-ui to 16.10.1.

New Contributors

• Maikel van Dort (@Netail) made their first contribution in #1868.
