+>
+The headline this release is a Studio timeline revamp: clips visible at the playhead are highlighted, tracks and individual elements can be hidden with a non-destructive `data-hidden` toggle that carries through to renders, and ruler zoom and gutter behavior are cleaner. It also fixes static-position dragging beside an animated rotation and keeps off-canvas indicators in sync with live layout.
+
+## Features
+
+- **Studio:** Timeline revamp with active-clip highlighting and hide controls ([037266e7](https://github.com/heygen-com/hyperframes/commit/037266e72bd808491a82008ca2520299fecef381), [#2017](https://github.com/heygen-com/hyperframes/pull/2017))
+- **CLI:** Associate signed-in HeyGen account with telemetry ([3d8372f8](https://github.com/heygen-com/hyperframes/commit/3d8372f880a6739ee3e0beea484905d76e5ad3a9), [#2020](https://github.com/heygen-com/hyperframes/pull/2020))
+
+## Fixes

+- **Studio:** Off-canvas indicators track live layout instead of going stale ([574da2b2](https://github.com/heygen-com/hyperframes/commit/574da2b215b29cc3e8288551ce37e7a06cdaa194), [#2018](https://github.com/heygen-com/hyperframes/pull/2018))
+- **Studio:** Static-position drag no longer freezes an element beside an animated rotation ([5d598354](https://github.com/heygen-com/hyperframes/commit/5d59835446bb426def56a791d19a99a6ebe283d3), [#2016](https://github.com/heygen-com/hyperframes/pull/2016))
+- **Skills:** Audit descriptions — trim routing prose, fix stale facts, add missing triggers ([306a291d](https://github.com/heygen-com/hyperframes/commit/306a291deaf8796cd2e9e34c406d707a7bdf3f7f), [#1990](https://github.com/heygen-com/hyperframes/pull/1990))
