As part of our ongoing efforts to upgrade the documentation on ros.org we are going to be migrating all existing content on docs.ros.org to use the en prefix to indicate that the content is English language and leave space for potential future internationalization efforts.
There are a number of directories on docs.ros.org they will all be moved to the /en prefix and http redirects will be setup to provide backwards compatibility for all urls from those directories.
The work is planned for late morning in California. There is not expected to be any significant outage between moving the directories and enabling the redirects.
After the changeover we will be reconfiguring all of the documentation jobs to use the new urls. This process will take a several hours and in the mean time symlinks will be maintained to ensure continuity.
And we are also going to be updating the services that we’ve identified as directly accessing the content including
Just ran into something which could be related to this migration.
The Code API link on the wiki/rospy package for Noetic links to this. This doesn’t actually open the API pages (like it does for Melodic and older), but shows a directory index page with two files (which appear to be related to the Msg API instead).
