The number of changes which we make for each release is so huge that we cannot highlight all of them even in the release notes. Because of that we have added a special page with extended release notes for each release like this one. Of course the tiny fixes cannot be included even in this list but if you are looking for the fix of some particular bug it makes sense to look through the big version of release notes.
But as usual there are some things in the release 21.2 that we especially want to draw your attention. More details about them are below.
