Vbulletin.org lets ya know when i release a minor bug fix becuase it changes the installed to green and i believe it says updated.
But yes I have been updating faster then even I can keep up with for updating the version numbers lol.
Right now im hoping to let v2.2.1 sit for a while so I can start working on v3.

But I will still fix issues with 2.2.1 as they are pointed out and any features i make for v3 that I can implement into v2.2 I will see about doing so.
