4 1/2 years later and it is still there in the feature comparison table 
Begs the question if TS6 will still support theses codecs.
And the comparison column against Skype, a software that does not exist anymore since May of this year, is also very valuable and should be preserved.
If TS6 ever leaves beta, it might also be a good Idea to update this and add new stuff. Like screenshare, media embeds, (custom) emote support and so on.
Until then maybe consider to add some foot notes to specify which feature is available in which client, as the big download link beneath the table sends the user directly to the TS6 beta download tab. A client that for example does not support 3D positional audio yet and might never do.
