Safari Technology Preview 32, with WebRTC, is Now Available
Safari Technology Preview Release 32 is now available for download for macOS Sierra. With this release, Safari Technology Preview is now available for betas of macOS High Sierra. If you already have Safari Technology Preview installed, you can update from the Mac App Store’s Updates tab.
This release covers the same revisions of WebKit from Safari Technology Preview 31 , but includes new Safari and WebKit features that will be present in Safari 11. The following web-facing Safari 11 features are new to Safari Technology Preview 32:
Safari prevents auto-play of media with sound on most websites. Users can control which websites are allowed to auto-play video and audio by opening the new “Websites” preferences pane, or through the “Settings for This Website…” option in the Safari Technology Preview menu. We recommended that web developers test their websites with these new behaviors, ensuring any custom media controls behave correctly when auto-play is disabled, either automatically or by the user.
Many more WebKit features in Safari 11 are present in this release of Safari Technology Preview and have been in past releases. You can learn more about what’s new in Safari 11 from the Apple Developer website.
