Unsolo = Unmute All?

To the Dev Team, and whoever else might know,
How come when I have five tracks, and two are muted, turning the ‘solo’ option on and off on one track unmutes everything? This was not behavior in the version of Audacity I used before. I was running 2.1.3, but I’m going to switch back to the old version. I work with inverted tracks fairly often, so having audacity automatically unmute everything for me when I didn’t tell it to is extraordinarily obnoxious. It is not the normal intent of someone toggling the solo option on a track to unmute any muted tracks.
Also, where did the ability to have more than one solo track go?
