No, they were written by upstream. The people doing Kolab for Roundcube are 
Thomas (founder or Roundcube) and Alec (most active Roundcube developer). The 
cooperation has turned out to be very beneficial for both projects, a lot of 
code that went into Roundcube 0.6 was developed as part of the Kolab 
integration.

That is only partly true.

Working on Horde always suffered from the fact that Kolab was still using 
Horde 3 while Horde upstream was already working in Horde 4 for quite a while. 
Unfortunately there was no reliable schedule, so for us it was unclear if we 
should spend time on H3 or H4. This prevented us from upstreaming our changes 
and Gunnar was the only one to maintain them.

So in the end Horde does not support Kolab upstream: H3 needs a whole lot of 
changes and H4 for Kolab is not yet finished.

Yes please. What I' like to know is when H4 for Kolab will be released [1] and 
if it is really upstream, means, that it only requires a few additional 
modules but no patches. This is what we have with Roundcube now: No changes to 
the codebase required, everything is implemented as plugins. Way easier to 
maintain.

Christoph
