DITA versions

Hi all,

I'm just reaching out and curious about what version of DITA you are using.

Also, has anyone upgraded DITA from 1.2 to latest version? or 1.3? 

If I'm not mistaken, Arbortext uses DITA 1.3. We are using 1.8 (or 1.2 not sure what the difference is) however, we made a few minor changes and maintain a 1.3 version to be used for Arbortext custom folder. At one point we upgraded Arbortext Editor and were getting a bunch of errors, we realized it was using 1.3, therefore we made the necessary changes and updated the schemas.
