Standard Library updates entries at Ruby 4.0.0 preview2 Released release note looks incorrect

rdoc 6.13.1
win32ole 1.9.2
irb 1.15.2
reline 0.6.1
readline 0.0.4
fiddle 1.1.6

Issues

  1. All of gems listed in the release note in English are bundled gems in Ruby 4.0, I'm not sure if these bundled gem versions should be listed in the release note section.
  2. These libraries are listed only listed in https://www.ruby-lang.org/en/news/2025/11/17/ruby-4-0-0-preview2-released/ , not listed in https://www.ruby-lang.org/ja/news/2025/11/17/ruby-4-0-0-preview2-released/
  3. Versions listed do not match the actual installed versions listed at https://github.com/ruby/ruby/blob/4fa6e9938cfb9458abd876ad4219a6648bfe1c96/gems/bundled_gems#L38-L47
    Here are differences:
ostruct 0.6.3
benchmark 0.5.0
rdoc 6.15.1
irb 1.15.3
reline 0.6.3
  1. readline versions listed 0.0.4 does not match with the actual version installed 0.6.3.
