2.0.0

A typed, ref-forwarding iframe wrapper for React 18 and 19.

Breaking

• Requires React 18+ (1.8.5 remains on npm for React 16/17)
• Dual ESM/CJS with an exports map; types live in dist/
• No object-assign runtime dependency
• No default display: initial or allowFullScreen="allowFullScreen"
• onLoad / onError use React event types

Fixes

• sandbox strings are no longer split into characters
• allowFullScreen honors the boolean and merges fullscreen into allow with semicolons (#139)
• forwardRef to the real HTMLIFrameElement (#54, #43)
• onLoad receives the synthetic event; onError is attached natively (#67)

Features

• Native iframe attributes pass through (srcDoc, fetchPriority, credentialless, referrerPolicy, …)
• srcDoc for inline HTML (#55)
• useIframeMessage and postToIframe helpers
