Anyone tried this update yet? I assume it addresses the same webkit security vulnerabilities as the recent iOS update as well as kernel, crash reporter and other various bits.

Apple release notes on the various updates are here.

On my i7 2600k hackintosh, it has installed correctly but on my Macbook Pro early 2011 patched with catalinapatcher from dosdude, the update doesn't install itself as the computer restart normally instead of restarting on install drive and I can't choose it manually when I go into bootloader. The security update (2020-001, build 19H114) before this one was ok.

I updated clover to 5122. System still showing booted version as 5089 but the software security update has been successful. ??? Will try to double check clover status later.
