[2025-10-20] v2.3.0 - Updated for Unity 6.3

SVG support and uss filters are now built-in!

• Runtime USS rework for Unity 6.3 compat
• Sample Scene updated for Unity 6.3 (added svg loading and filter usage)
• Improved float parsing in DomStyle (culture-agnostic)

• Puerts filepath handling with spaces
• CI Mac shell fix
• Added ScriptEngine.Refresh()
• More webgl build tweaks
• Tighter GetLength() in DomStyle

• SimpleGrid bugfix
• Game UIs CI test
• DomStyle caching

• CultureInfo.InvariantCulture for Length parsing
• EditorScriptEngine updates

• Delayed EvalFile(). This ensures the inital mounting happens after the initial UIDocument load (so that the initial layouts are already calculated).
• Added an extra ".root" css specificity to generated TW classes.

Improved some workflows to support the rollout of our game UIs.

To upgrade from a previous version:

• make sure to update onejs-core and onejs-preact to ^2.0.0
• The following defaults have changed:
  • postcss.config.js, tailwind.config.js, tsconfig.json
  • input.css, .vscode/tasks.json
• You can delete them and run scene with ScriptEngine again (be mindful if you have custom changes)

To install OneJS's Game UIs, you can now run:

npx oj add all

This will work as long as you have a premade-uis.tgz(.bytes) file anywhere in your Assets/ folder. This file is only included in the OneJS Asset Store package.

onejs/math is now available! See onejs-core repo for more info.

• Better custom UIElement Events handling
• Normalized Path in ScriptEngine.GetFullPath()
• EngineHost.subscribe() improvements
• Better uss class name escaping
• Many Editor UI improvements
