Is there official support or support planned for Messenger:Mac/MSN Messenger for Mac? I really cant find lot of mentions for compatibility other than this: https://github.com/atauenis/webone/wiki/Using-with-MSN-Messenger

According to it escargot can work with Messenger:Mac/MSN Messenger for Mac up 3.0 version, newer version do have problems.

I would like to know official support of Mac versions if any exist or if it is planned on future versions?

as far as i know, there is official support, as seen in news part of the website
