According to my calculations, this means Firefox 100 will be released on 2022-03-08.
In general I like more the classic/old way of versioning the releases, like for example "1.2.2" which has some embedded meaning of what is changing (e.g. . . ) which hints at how potentially dangerous an upgrade might be or if some new exciting stuff has been included. Jumping directly from 10 to 11 to 12 leaves me clueless without reading all release notes :(
It's not so fun to work around because Windows Installer tries to be smart about things, as opposed to the others that take a more robust approach.
