+### Arbitrary iframe embeds ([#8306](https://github.com/tldraw/tldraw/pull/8306))
+
+Paste any `<iframe>` embed code onto the canvas to create an embed shape. Previously only URLs matching known providers (YouTube, Google Maps, etc.) worked. Now any valid iframe with an HTTP(S) source creates an embed directly, supporting services like OpenStreetMap, SoundCloud, Loom, and more.

 ### Cross-window embedding support ([#8196](https://github.com/tldraw/tldraw/pull/8196))
 
 Tldraw now works correctly when embedded in iframes, Electron pop-out windows, and Obsidian plugins where the global `document` and `window` differ from the ones tldraw is mounted in. All bare `document` and `window` references have been replaced with container-aware alternatives.
