+The last release turned the audio effects rack on for everyone. This one fixes

+
+## Features
+
+- **Engine:** Renders no longer finish with the drawElement self-check silently
+  switched off. That check compares frames with ffmpeg's `psnr` filter, and an
+  ffmpeg built without it made every comparison fail quietly. HyperFrames now
+  tests for the filter once at startup and captures by screenshot instead when it
+  is missing ([073b098e2](https://github.com/heygen-com/hyperframes/commit/073b098e21aa006571b60c446711c6dff57a2eac), [#3418](https://github.com/heygen-com/hyperframes/pull/3418)).
+
+## Fixes
+
+- **Studio:** The effects preset list on a timeline track no longer runs off the
+  top or bottom of the window. It fits the space it opens into and scrolls, so
+  every preset and both footer buttons stay reachable ([277fe0fa2](https://github.com/heygen-com/hyperframes/commit/277fe0fa221756480928605d71590ead55cbfb64), [#3413](https://github.com/heygen-com/hyperframes/pull/3413)).
+- **Studio:** The timeline's popovers and menus can no longer be painted behind
+  other parts of the app. Every panel that floats above the timeline now sits on
+  the same layer as the rest of the studio's popovers ([8612cfd40](https://github.com/heygen-com/hyperframes/commit/8612cfd40fcfd2d4dae6bff6b9b9ac940c7e7bbd), [#3414](https://github.com/heygen-com/hyperframes/pull/3414)).
+- **Studio:** The expand arrow on an audio group row is back to the size and
+  shape the properties panel uses, instead of a smaller rotated one ([c59402389](https://github.com/heygen-com/hyperframes/commit/c59402389555ef2fca455e504fa40c5773354cf3), [#3415](https://github.com/heygen-com/hyperframes/pull/3415)).
+- **Skills:** The voiceover carve command now runs in your own project. It could
+  not load HyperFrames from a published install at all, and the error it printed
+  suggested reinstalling, which never helped. It also records the voice group
+  rather than a list of clip ids, so a narration clip added later is covered
+  without editing the carve ([f0cc9b1a3](https://github.com/heygen-com/hyperframes/commit/f0cc9b1a3441522797cfe06dc3892ac2065c7bf2), [#3416](https://github.com/heygen-com/hyperframes/pull/3416)).
+- **Producer, CLI:** A render that cannot find its manifest now lists every path
+  it looked in, instead of naming one ([718bf5ef3](https://github.com/heygen-com/hyperframes/commit/718bf5ef32d4e521f686ea6ebe64545a6a2647ed), [#3387](https://github.com/heygen-com/hyperframes/pull/3387)).
