Well, that is not how things work... and how they should work. There will now be series of dev releases, adding things. Usually, they are pretty stable, but right now we are in the middle of D&D issues which makes it a little bit unstable - till next week or so.
Anyway, more people using "dev" for the real work the faster we get it stable.
BTW, just checked those tooltips, seems working to me.... (but is is possible it was some intermediate phase).
