Apple on Wednesday released Safari Technology Preview 130, the latest version of their developer preview web browser. The preview version of Apple’s popular browser offers developers and other interested users the ability to try out features that may or may not, debut in future public release versions of Safari.
Safari Technology Preview release 130 is built on the new Safari 15 update included in macOS Monterey, and as such, it includes several Safari 15 features.
Note: Tab Groups do not sync in this release. On macOS Big Sur, this release requires enabling GPU Process: Media option from Experimental Features under the Develop menu to address issues with streaming services.
