How's Safari 15.0?

I have a stable 11.6.0 install with OC 0.7.3 and got a prompt last night to upgrade to Safari 15.0. I'm running SMBIOS iMac Pro 1,1 and have no issues with DRM in Safari or on Apple TV at the moment. I had quite the surprise when I switched from Mojave to Catalina and DRM support in safari broke. Not only that but if I visited Netflix with Safari it would freeze my entire machine! Wasn't fixed until the second half of Catalina's update cycle (10.15.4). Needless to say, I'm wary to update now. Looking to avoid surprises if I can. Are there any known issues with Safari 15.0 in the Monterey Beta? I do have a bootable backup via Carbon Copy Cloner but figured I'd ask first before hitting the update button. Thanks all!
