The PAN-OS 10.1.10-h2 software update is now available on the Palo Alto Networks Software Updates page. Check out the PAN-OS 10.1.10-h2 Release Notes for release details, including the new features and bug fixes that make the upgrade worthwhile.
The Preferred Release page hasn’t been updated yet to show 10.1.10-h2, and still shows 10.1.10-h1 as the preferred release in the 10.1 release branch.
Yeah, usually it takes a few weeks or even months for the preferred version to be changed, unless there is a major security issue fixed. But usually the page lists the new version pretty quickly, just doesn’t mark it as preferred.
