What's New

• Support passing a version prefix argument by @byroot in #2610

  Before, Ruby versions needed to be specified in full as arguments to ruby-build, e.g. rbenv install 3.4.9. Now, a version prefix may be passed targeting a major Ruby version or a specific alternative Ruby implementation:

  rbenv install 3    #=> installs latest Ruby 3.x (3.4.9)
  rbenv install 3.3  #=> installs latest Ruby 3.3.x (3.3.11)
  
  ruby-build --dir ruby-4 ~/.rubies   #=> creates `~/.rubies/ruby-4.0.3`
  ruby-build jruby-10 /path/to/jruby  #=> installs latest JRuby 10.x
  ruby-build TruffleRuby /path/to/truffleruby  #=> installs latest `truffleruby-x.y.z`
  
  # the special keyword "ruby" resolves to the latest stable CRuby
  rbenv install ruby  #=> installs latest Ruby (4.0.3)

  The new --resolve flag can be used by scripts and other tooling to resolve partial version names to full ones:

  ruby-build --resolve ruby-3.3
  #=> 3.3.11

• Add mruby-4.0.0 by @mislav in #2620
