Currently the only way to see what "Version" the Avatar you're uploading is, is through the SDK Builder Panel.
I think this should be actually used in-game, with a line added in your Avatar Details showing what the Version Number of your Avatar is returning.
In addition, I would like to see a feature where it would be possible to make that same version number be inserted automatically in your Avatar's Name (at the user's discretion) through a text argument in the SDK Builder Panel. Something like <!version>, which would insert the Avatar Version number in place of that argument.
Example: An Avatar named "Dragon v1.0.<!version>" that has the Version 4 in the SDK, would return as "Dragon v1.0.4" in-game.
