Back in the times of ROS 1, I was used to read the “New packages for Turtly Turtle” post, click on the packages I’m interested in, which usually led to ROS wiki, and directly there, I could look at the changelog for that particular distro.
I haven’t found anything like that in ROS 2. The links usually lead either to external doc sites (like nav2 or ros control), or to github (if lucky, they lead directly to the correct branch). Then I have to go to commit history, find the changelog-updating commit and look around (or open the one package and check its CHANGELOG.rst). There is also an attempt at changelogs at index.ros.org, but it apparently doesn’t work: nav2_planner - ROS Package Overview . The changelog is empty. And even if it worked correctly, there’s no direct link from the news post to the package’s page at index.ros.org (but this shouldn’t be that difficult, right?).
The change log in ROS index is an accurate representation of the package change log upstream which looks to be empty.
It would be good to update the announcement script to point to the index. That certainly isn’t hard, it wasn’t done originally because the script predates the index. With a request or even better a pull request it can be a quick fix away:
