With the release of the premium plugin, this contains a lot of long-awaited for features.

• Custom Disguises, you can now create a custom disguise in disguises.yml then use those disguises as you would a normal disguise. One disguise is added as an example: libraryaddict
• Constantly displaying player disguises in tablist, you no longer give away that its a fake player, they can even see him in tab! This is disabled by default.
• Hiding disguised players from tab, this is disabled by default.
• Tab complete on commands, this includes not only the disguises, but the disguise options and the disguise option values where applicable
• ItemStacks in commands can now use the Material instead of item ID
• Metadata bug introduced with 1.11 has been fixed, you can now see disguises sprint and sneak again
• A message that announces the server supports the plugin author on command usage, doesn't really mean anything. Its just something that would be interesting to see.
• A new disguise config option to disable all invisible disguises, this is disabled by default.
• Fixed evoker fangs, self disguises flickering
• Fixed entity itemstacks being completely broken, this was done by creating my own implementation that implements EntityEquipment which some plugins may use.
• A few other small bugs has been fixed

9.2.2 was released to fix a small setSkin bug in Player Disguise
