Not sure when we're actually ready to pull the trigger here - will require migrating vendored gems to 3.4 in brew and making sure everything works ok (since, from experience, reverting vendored gems changes is usually very messy and best avoided so we'll want to fix forward). Usually do a minor release but on reflection seems like we maybe will be able to get away without one this time if we wanted. Definitely mattered back when we did 2.6 -> 3.1.x as that required formulae changes in some cases and larger system Ruby shifts.

It is a breaking change for formulae if they use any of these: https://rubyreferences.github.io/rubychanges/3.4.html#default-gems-that-became-bundled, though we'll handle Base64 at least given that's probably the main one used there.

The build now works though at least. I've not forwarded patches upstream yet but they are trivial and I will do so later this week.

Extra considerations for brew:

• Vendor base64? Usually not necessary for most cases (since pack/unpack can do the job), but probably worth it for compatibility with formulae: https://github.com/search?q=repo%3AHomebrew%2Fhomebrew-core+%22Base64.decode%22&type=code. This should help prevent the main breaking change here.
• csv in brew contributions? Assuming --csv is used, probably make it pulled in by a brew install-bundler-gems group. Or just do a simple implementation that doesn't need the gem.
• mutex_m in Debrew - will maybe bin this I'll check.
• All parser/current references need to go - not supported in 3.4. Only usage seems to be https://github.com/Homebrew/brew/blob/0046519c08cd3967e0934c82195361ac7e76c567/Library/Homebrew/rubocops/shared/helper_functions.rb#L247, which looks hacky as is so worth seeing if we can refactor away the need for that.

Will need to check if this is a problem: https://rubyreferences.github.io/rubychanges/3.4.html#reserved-module-ruby
for: https://github.com/Homebrew/homebrew-core/blob/master/Formula/r/ruby.rb.

While loading the file directly will omit warnings, the way Formulary loads into a dynamic namespace should avoid this problem but worth checking.

@MikeMcQuaid mentioned that he wanted it to coincide with the release of Homebrew v4.5.0. I think that makes sense.

• Vendor base64?

I think I handled that in Homebrew/brew@7504258, but let me know if there's anything else I may have missed.

Ah right, the TODO just needs removing from here then: https://github.com/Homebrew/brew/blob/0046519c08cd3967e0934c82195361ac7e76c567/Library/Homebrew/api.rb#L7

Works for me. I'll plan 4.5 🔜.
