So I agree with raidflex
It took me a day of reinstalling after a borked gui updgrade on 9.10 release. I bit the bullet and went for Coral as it was a month since release. I hit issues with plugins not loading, so it never booted.
I had to go back to a fresh install, and after i EVENTUALLY found some links to the fact Coral was pulled I felt like I had wasted my time.
To top this off, Linux Format featured it as a new release in May edition, and then a full review of Coral in the June edition.. when its been pulled and un supported? No mention of that in the review that I seen.
Please, make some sort of blog or announcement, make it clear on the download page why your getting a 9.10 release and not Coral. Seem as I was emailed about the amazing Coral, it would have been helpful to have been told it was getting dumped... with the same level of publicity.
For what its worth, I've put together that 9.10 -> 11 is the way to go. Coral has been left as a stand alone, not supported thing, and the features it had will go to 11 over time. It shouldn't have been so difficult to find out though.
