VaMX is updated to the latest version of Virt-a-Mate. VaMX receives updates to the latest version of the vamX plugin (where new features are constantly added) every 6 months. It arrives in a single Mega Update (with more testing the normal monthly updates) with all vamX VIP features (which are normally $10 per month). So the itch.io version is updated infrequently, but updates are free forever (instead of paying $10/month for the vamX Patreon features). If you are very very eager to get an update, you can pay the $10 one time to update ahead of schedule.
The updates come out approximately twice per year. They include all improvements from the VIP versions of vamX (which people subscribe and pay monthly for) but free forever (although much less frequent). There is another update coming soon. We want to release the January version for free but will wait to make sure there aren't any bug reports from the VIP users, then once this version is considered stable it will be released. Probably by the end of January.
