Version v1.82.1 Changelog September 21, 2026

New Features

Licensed Codec Packs

  • Engine/Node: Added support for licensed codec packs downloaded from the licensing dashboard on Linux x86_64. Packs are automatically detected in $HOME/.local/share/cesdk-codecs; set CESDK_LICENSED_CODEC_PACK to use a custom installation directory.

Bug Fixes

Engine

  • Undo, redo and applying a template no longer crash when the scene holds a page without a parent. Such a page is one that is not appended yet, or a duplicate made with attachToParent set to false. Page carousel mode no longer crashes on such a page either.
  • A video export of a page no longer hangs at the first frame when a block on another page is still loading. A block with an error on another page no longer cancels the export.
  • A video export of a page now draws only the blocks of that page, as an image export does. A block outside that page, for example on another page at the same place, no longer appears in the video.

Engine (Web + Node)

  • A string with a lone UTF-16 surrogate, such as text cut in the middle of an emoji, no longer loses characters or breaks the scene. The engine stores U+FFFD in its place, as @cesdk/node-native does on Node.js and Deno. On Web, a scene saved with such a string now loads again. A scene that an older release saved with such a string still fails to load.
