I have built and am testing the RC1 version
I had to install these packages for the build to succeed
libimlib2-dev librsvg2-dev libstartup-notification0-dev
Also beware that this version sees all subdirectories under the launcher_apps_dir setting... so if you have any additional launchers in a subdirectory (like I did) they will also show up on the tint2 panel
All things work as advertised and so far I am impressed that everything is the same and functional
I do not mess with nor ever will use tint2conf... you are on your own with that crap...
