I noticed that
MBS-1934 removed the "see other versions of this release" vs. "see release group" difference. The wording may not have been optimal, but without this difference, the usability of the site is reduced for me. I used that difference a lot to tell if a release group contained more than one release.
The text now is completely misleading: It says I will see other versions of the release if I click on the link, even if there is only one release.
