I just realized that I added this doc update to 2.7, without knowing where the change will be released. If the actual change will be in a point release of 2.6 let me know and I will add the change to the 2.6 docs as well.

2.7 is the correct one.

Could you please update the artemis docs for the previous versions as well? (the cors header is present there).

@zroubalik - Done. It appears that the corsHeader was added to Artemis back in release 2.3 so I have updated the docs going all the way back to 2.3. I also fixed a small formatting error in the 2.7 docs where I had one two many spaces in the list.
