There is only the implementation of adding the target attribute with JS because of the ready-for-delivery cached entries. That's all. As far as I remember you halted the JS-side implementation until the server sided code is ready.
I haven't done anything in the last time, because I want us to draw a line under a final release. In my opinion, it was not a good idea to collect and to implement features by features by features without providing a new release as new starting point.
I support your sight on the decision to collect feature wishes and to wait with publishing a next version for a complete implementation of all wished features. As I stated to it was a completely wrong decision mainly made by me.
I'm already worried that I won't be able to find a way back to the official version.
Did you patch your forum so heavily?
So, in short, I will not contribute any code to the forum until the official version 2.5 is available. Otherwise I dig my own grave by handling different versions etc.
I completely understand your decision.
PS: I had to reconstruct your entry because I edited it in a first attempt instead of replying to you (once again).
