Custom Apps in Patch My PC Cloud now supports custom detection rules, using native rules in Intune and also custom scripts: https://ideas.patchmypc.com/ideas/PATCHMYPC-I-4767
This feature request is to allow customers to implement major/minor versioning control for their detection and requirement rules (ref https://ideas.patchmypc.com/ideas/PATCHMYPC-I-7563).
For example, a customer may make a Custom App for 3.2.1 and only want it to install on devices with versions less than 3.3 but greater than 3.1 - similar to how Patch My PC handles version "fencing" (via SQLSearchVersionInclude) in its own catalogue for Snagit's major version and Python's "major" minor versions.
