12:06 PM Ruby Bug #21696: Performance degradation for long running processes in Ruby 4.0.0-preview2

Did 3.5-preview1 have the same behaviour? If not, could you bisect between the two releases to find the commit that changed the behaviour? ufuk (Ufuk Kayserilioglu)

02:52 PM Ruby Bug #21654: Set#new calls extra methods compared to previous versions

IMO, ranges should behave the same when `end == Float::INFINITY` and when `end == nil`. They are both practically endless ranges, but nothing normalizes them so that they always behave the same. Maybe `(1..1/0.0)` should be internally tr... ufuk (Ufuk Kayserilioglu)

01:48 PM Ruby Misc #21657: Question: Is Ruby 4.0 planned for December 2025 or later?

It seems like the next version of Ruby will be branded as 4.0, but that is completely a decision for @matz to make as he wishes. Ruby version numbers don't follow semantic versioning, so 4.0 doesn't mean that there will be breaking chang... ufuk (Ufuk Kayserilioglu)

04:57 PM Ruby Feature #21346: Introduce `String#ensure_suffix`

I personally find the `"Hello".ensure_suffix("o!")` case returning `"Helloo!"` very unexpected. I would have expected the change in the string to be the minimal operation needed to ensure that the string ends with the given suffix (i.e. ... ufuk (Ufuk Kayserilioglu)
