The curent roadmap is located on the KDE Techbase.

New Features for 0.12:

Chat window:

Adium style chat window themes

• Kopete has removed support for the old XSL based chat window themes and now supports the same chat window themes that the Mac OS X client Adium uses. A few themes will be included in Kopete and there are many more available for download at AdiumXtras

Yahoo:

New Protocol Implementation

• The next version of Kopete will feature a new Yahoo! protocol backend based on the Task architecture that is in use in the OSCAR (AIM/ICQ), Groupwise, and Jabber.

Jabber:

Experimental support for Jingle voice chats

• Kopete now features experimental support for Google Talk voice chats. Please keep in mind that support for this feature of the Jabber protocol is completely experimental and is something that the user will have to use at his/her own risk.
• Support for Offline Messages
• Support for Jabber Transports

AIM:

• Support for AIM Chat Rooms
