Apple has released a beta version of Safari 10, the next version of its web browser for Mac, for OS X Yosemite 10.10 and OS X El Capitan 10.11. The beta can be downloaded for either system at Apple's Developer Downloads site.
While it will also arrive later this year for macOS Sierra, Safari 10 will also bring some of its enhancements to the older operating systems. While those won't include things like Apple Pay on the web or picture-in-picture mode, it will include some changes such as design enhancements. Developers can get a full list of what's new for them in Safari 10 right here.
