08:49 PM Ruby Bug #21672: `IO::Buffer.new` does not check that flags are valid

@trinistr First off, Thanks for your work on specs recently. I did a quick implementation of IO::Buffer for j Ruby last year but only relied on the core tests. Having a complete set of specs will be very helpful.

08:03 PM Ruby Misc #21657: Question: Is Ruby 4.0 planned for December 2025 or later?

I don't personally have a strong opinion about jumping to 4.0 purely for symbolic reasons, but if it's going to happen, it seems clear the community needs to know right now so we can start dealing with these issues.

12:13 AM Ruby Feature #21665 (Open): Revisit Object#deep_freeze to support non-Ractor use cases

## Proposal: Introduce `Object#deep_freeze` (or similar name) to freeze an entire object graph

All encodings get Marshal.dump'ed with an encoding instance variable:

08:27 PM Ruby Bug #21151: IO and StringIO raise FrozenError even for read-only methods

Edit: previously I referred to non-writable state, but in actuality any state of `StringIO` or `IO` should be safe to read even if the object itself is frozen. There's no need for either type to be mutable just to read `sync` or `externa... headius (Charles Nutter)
