Side note: I don't know how often this happens but it's kinda cool that Firefox went straight from 87.0 to 88.0 without any sub-versions. They didn't seem to have any security/bug patches, they just got it right on the first try.
And this apparently happens quite a lot [no security patches in between versions]: https://www.mozilla.org/en-US/security/known-vulnerabilities...
Not that I much care - FF4Lyfe here!
Personally I would prefer to keep things as simple as possible, but unlike the maintainers of those projects, when it comes to making releases, I'm not perfect.
