Requiring a Minimum HugsLib Version - UnlimitedHugs/RimworldHugsLib GitHub Wiki

Update required window

When your mod relies on a HugsLib feature not present in earlier versions, it's a good idea to specify a minimum version requirement for the library. On startup, HugsLib will check its version against the requirement, and notify the player if an update is needed.
This helps to avoid cryptic errors which will prevent your mod assembly from loading- with zero errors, if dev mode is off.

To specify a minimum HugsLib version, add a /About/Version.xml file with the following contents:

<?xml version="1.0" encoding="utf-8"?>
<VersionInfo>
	<requiredLibraryVersion>8.0.0</requiredLibraryVersion>
</VersionInfo>

Replace the requiredLibraryVersion tag contents as needed.
