 ### Features
 
+- Added hand-drawn font for Chinese, Japanese and Korean (CJK) as a fallback for Excalifont. Improved overal text wrapping algorithm, not only accounting for CJK, but covering various edge cases with white spaces and text-align center/right. Added support for multi-codepoint emojis wrapping. Offloaded SVG export to Web Workers, with an automatic fallback to the main thread if not supported or not desired.[#8530](https://github.com/excalidraw/excalidraw/pull/8530)
+
 - Prefer user defined coordinates and dimensions when creating a frame using [`convertToExcalidrawElements`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/excalidraw-element-skeleton#converttoexcalidrawelements) [#8517](https://github.com/excalidraw/excalidraw/pull/8517)
 
 - `props.initialData` can now be a function that returns `ExcalidrawInitialDataState` or `Promise<ExcalidrawInitialDataState>`. [#8107](https://github.com/excalidraw/excalidraw/pull/8135)

 ## 0.16.0 (2023-09-19)
 
-- Add a `subtype` attribute to `ExcalidrawElement` to allow self-contained extensions of any `ExcalidrawElement` type. Implement MathJax support on stem.excalidraw.com as a `math` subtype of `ExcalidrawTextElement`. Both standard Latex input and simplified AsciiMath input are supported. [#6037](https://github.com/excalidraw/excalidraw/pull/6037).
 - Support creating containers, linear elements, text containers, labelled arrows and arrow bindings programatically [#6546](https://github.com/excalidraw/excalidraw/pull/6546)
 - Introducing Web-Embeds (alias iframe element)[#6691](https://github.com/excalidraw/excalidraw/pull/6691)
 - Added [`props.validateEmbeddable`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/props#validateembeddable) to customize embeddable src url validation. [#6691](https://github.com/excalidraw/excalidraw/pull/6691)
