Thank you! :smiley:

With our quick release comes a small "issue" that we implemented Class#descendants, while it got removed from Ruby 3.1 last minute.

     - The calls to `==`, `!=` and `===` changed their semantics
    slightly: it's impossible to monkey patch those calls for `String`
    and `Number`, but on other classes they can now return `nil` and
    it will be handled correctly
     - The calls to `!` changed their semantics slightly: it's
    impossible to monkey patch this call for `Boolean` or `NilClass`.
    - Refactored the structure of the internal `stdlib/nodejs` folder
    ([#2374](Docs & opal/platform fixes by elia · Pull Request #2374 · opal/opal · GitHub))
     - Added `nodejs/base` with just I/O, exit, and ARGV management
     - Moved `Process::Status` to corelib
     - Fixed requires to be more robust

    ### Removed

    - Removed `nodejs/irb` from stdlib as it's been broken for some
    time ([#2374](Docs & opal/platform fixes by elia · Pull Request #2374 · opal/opal · GitHub))
    - Removed `Kernel#node_require` from `nodejs/kernel` as it's been
    deprecated for a long time
    ([#2374](Docs & opal/platform fixes by elia · Pull Request #2374 · opal/opal · GitHub))
