AI CC 2015 availability
Not sure where this belongs. I am disappointed Adobe does not make older software available for download. In production environments changing software yearly is not practical. Custom scripts are optimized for a specific version and "upgrading" software is usually of no value since we are not working with any of the "spiffy" new features anyway.
Another reason AI CC 2015 is important to our workflow is how it works with the Adobe EmojiOne font. This font renders ONLY in color on the latest versions of Illustrator. But in AI CC 2015 the font renders in black and white. Why Adobe has chosen to disable the black and white emojis is beyond me. There are MANY reasons it should remain available.

Yeah I could love as well to have access to even ancient versions, I have a frozen in time macbook 2009 that I want to keep in isolation without internet with OSX 10.6 but it only run the very first CC version that is no longer available.
