Is the Tridion 2013 Anguilla GUI Extension framework (and 2013 SP1) backwards compatible with Tridion 2011 SP1 HR2?
I realize that there are significant Message Centre changes in Tridion 2013, but this seems to be added API functionality keeping the existing functionality as is (except for the look-and-feel), and the basic stuff from 2011 SP1 should hopefully still work.
I've looked into existing threads on this topic, but don't see a clear answer.
Tridion 2013 MessageCenter, how to display message? - the correctly marked answer seems to indicate that there is a slight change in how to invoke messages, yet the other answers indicate that there is no change.
Tridion 2013 vs 2011 SP1 architecture - doesn't mention any non-backwards-compatible changes to Anguilla.
Upgrade to SDL Tridion 2013 - doesn't mention any non-backwards-compatible changes to Anguilla.
I've also checked out the article on SDLTridionWorld regarding hooking into the Message Centre for greater messaging ability: https://sdltridionworld.com/articles/sdltridion2011/signalr_messagecenter.aspx - this mentions that the solution works 2011 SP1 (and I'm starting to deduce will work for 2013 as well).
Would you please share your experiences and facts on this?
