After the stable version of Tencent QQ 2005 released, many many powerful person try to add funny features to it.
I have looked through almost all QQ versions, they are:
Soff – 珊瑚虫3.2.1a
pyqq.cn – 飘云QQ简装版
icnns.com – 中国黑客精简版(No release for stable version now)
快乐无极,工作狂人,etc….
Only the pyqq and icnns versions are fit to my style – performance and resources.
But almost all versions have many bugs. For example, icnns version will change your input method….I don’t know why, some people said that is a bug of QQ2005Beta3. Also some people provide the fix of this bug. But the fix depends on experience of programming.
So, the official version is the best to a normal user.
