Somewhere in the last twenty revisions, multiplayer text sending has sort of broken, the 'currently typing' line you display after you hit 1-4 doesn't show at all, and if you type whilst in respawn you don't even have any idea whether you've sent the text or not...
It also appears that the tracking hostile target / tracking target indicator behaviour has changed slightly (hard to explain, if only a single target is targetting you, and you have that target targetted, both triangles can display on screen when normally the hollow one would disappear altogether, dunno if it's effected it's normal functionality much, doesn't /seem/ to have.
