Well, after a long time without any news it seems now we're close to different updates about AMFPHP
As you probably know Wade Arnold
took the place of Patrick
some time ago as project leader but no real big changes were committed since then.
Bt, as Wade said
, the amfphp core will remain separated from the framework implementation ( a framework which I will never use however ), in order to have a shared core and 2 different branches for the implementation. ( a new release was promised before Adobe MAX )
However I'm afraid too about what could happen expecially when 2 major software houses "promote" an opensource project.
Probably I'm too sceptical, but I believe that in the future more and more things will be only supported in the zend_amf and not in the standalone amfphp project.
