It varies. My impression is that binary debs are usually available
within a week after the source release.

It means packages under development for the next distribution. Not
necessarily WG.

Unstable was used to develop packages for diamondback. Now that
diamondback beta is out, they are (roughly) the same. Once the final
diamondback distribution is released, unstable will begin development
for the next distribution (E-turtle).

New deb binaries will be released as available. You should get them
automatically via System>Administration>Update Manager or "sudo
apt-get upgrade".

No. The cturtle packages are not compatible. There have been binary
interface changes.

For diamondback, the packaging became less monolithic. People are not
expected to download almost everything. REP 108 explains the new


Different variants comprise various subsets of the packages. I see
there is a care-o-bot variant, so you should get most of what you need
by installing ros-diamondback-care-o-bot.

Since that does not appear to include ros-diamondback-camera-drivers,
you may need to install that separately. If most or all care-o-bot
users need the camera_drivers, someone should probably add it to the
care-o-bot variant.
