# Motion 13.5.1

By Steven Van · 2026-10-02

Motion 13.5.1 restores an internal scroll API for 13.x compatibility and fixes bugs in styleEffect, svgEffect and inherit={false}.

Motion 13.5.1 is a patch release with one fallback change and several fixes, including a restored internal API that some 13.x code still depends on. It is the library behind [Motion Studio](<https://creatorstoolbox.com/tools/motion-studio>), and the [changelog entry](<https://motion.dev/changelog?lib=motion#13-5-1>) lists these changes:

## Changed

- readSVGValue now falls back to the attribute when computed style is empty.

- Internal changes to animateChanges for size reductions.

## Fixed

- **scroll:** the removal of the internal observeTimeline API is temporarily reverted, which fixes compatibility with previous 13.x APIs. Motion is moving to pinned dependencies before removing it in 14.x.

- **styleEffect:** cleaning up an earlier value no longer removes a value that was bound to the same key after it.

- **svgEffect:** transforms and origins are no longer written as attributes.

- **motion:** inherit={false} now correctly does not inherit parent animations.

- **motion:** sortNodePosition no longer throws when a sibling hasn't mounted.
