For some time I haven’t seen the “Release notes” paragraph on the installation pages of my browser extensions. But then suddenly one day I saw it on one of my extension, only for being gone the next time I visited the installation page.
Digging deeper, it looks like it isn’t visible on “en-GB” version of the installation page. But it is visible on f.ex “da”, “es” and “en-US” versions of the install page? :
