v1.2.4 is the newest version of Mage. I stripped out v2 tags in order to keep go modules from requiring the /v2 import path. Mage is and always will be backwards compatible with earlier versions, so there's no reason to move to v2. I had originally moved to v2 with the thought that every new release would be a new major version, since Mage doesn't really need semantic versioning... but that was before semantic import versioning came around.
Apologies for any problems this causes anyone.
