Progress on various Pidgin / libpurple features:

MSN support

Past

Google SoC 2006 project on MSNP13 support: the first start on future MSN protocols support, was apparently never merged so it was not complete enough.

Google SoC 2007 project on MSNP14 support: UpdateMsnSupport, continuing from last summer. Did not produce completely problem-free functionality, but a base for what is now in Pidgin trunk and can be enabled by modifying configure.ac.

A branch of Pidgin has also been created for MSNP15 support. Remaining tickets for MSNP14 and MSNP15 are assigned to the "Activate MSNPV14" target in roadmap: ​tickets

​msn-pecan: An actively developed alternative MSN protocol plugin.

Future

Two choices, fixing and activating current MSNP14/15 code or merging msn-pecan. According to the msn-pecan's web site, there have been some disputes between other Pidgin developers and the msn-pecan developer, so it's not clear that the merge will happen without someone's "social engineering" in-between.

Voice & Video

Past

Earliest progess: ​gaim-vv. In 2005 it was stated that gaim-vv people were merging with the gaim proper (gaim is what pidgin was called before). However, this did not happen and the code bases are too different now without a big amount of work.

Could someone add some facts if gaim-vv people are still around or something?

Future

As part of Google's Summer of Code 2008, a voice and video project has been accepted. The plans are to first implement and stabilize voice and video on XMPP (making adding GTalk trivial) and then continuing onto the other protocols.
