Where to find info/changelogs of ROS package releases
I'm on Ubuntu 16.04 and get updates of ros-packages from time to time via apt(-get). One can observe that they're released in "bursts", so a group of packages are released together. Everytime I update the packages, I wonder what the actual changes are and how they affect my projects, but I have no clue where to look it up. Of course, I could search github for each package, find out the package version (not to mix up with the release version!) and look into the changelog, but this seems very cumbersome. Isn't there a unified Changelog for those burst-releases?
