		## [2.1.0-alpha.0] - 2026-04-24

		Alpha preview for iframe fullscreen support. Published under the `next` dist-tag — stable `latest` remains on 2.0.0.

		### Added

		- Iframe fullscreen protocol: Two new inbound postMessage events (`REQUEST_FULLSCREEN` and `EXIT_FULLSCREEN`) let the embedded UI expand the iframe to cover the entire parent viewport and then restore it. Works uniformly in modal and inline modes and on iOS Safari (no reliance on the native Fullscreen API). The iframe's inline style and the parent `body.overflow` are saved on enter and restored on exit. `RESIZE` messages are ignored while fullscreen is active so the UI cannot clobber the expanded height.
