Documentation needs backporting #111
Description
docs.ruby-lang.org renders docs only for major versions: there is docs for 2.7.0, but not for 2.7.1 -- which implies that https://docs.ruby-lang.org/en/2.7.0/ actually contains "Generic 2.7 docs". At the same time, documentation is frequently fixed after the release. This way, documentation that is relevant for version x.y.*, but was NOT there at x.y.0 will NEVER be rendered. Some examples:
- What's the pattern matching syntax for 2.7? The PM docs were written after the release, so they are accessible by https://docs.ruby-lang.org/en/3.0.0/doc/syntax/pattern_matching_rdoc.html (it is 3.0's PM!), or https://docs.ruby-lang.org/en/master/doc/syntax/pattern_matching_rdoc.html (was 2.7's before 3.0's release, now it is 3.0's too).
- My method definition docs update was merged AFTER the 3.0 release. So endless methods and
...argument forwarding are documented here: https://docs.ruby-lang.org/en/master/doc/syntax/methods_rdoc.html, but not here: https://docs.ruby-lang.org/en/3.0.0/doc/syntax/methods_rdoc.html (implying they aren't in 3.0 at all)
I believe that something should be done about it, probably at least on releasing 3.0.1 its docs should be merged into 3.0.0 URL, or maybe rendered separately at https://docs.ruby-lang.org/en/3.0.1. Or, maybe, the docs should actually be backported into 3.0.0? Because if the Ruby installed with the local docs, 3.0.0 would forever lack them.
