I want to push back on this - it might be one-time pain to fix, but it will prevent annoyances for Ruby users for years to come w... bdewater (Bart de Water)

08:10 PM Ruby Misc #21833: Switch default hash from SipHash13 to XXH3?

FWIW
- https://github.com/Nicoshev/rapidhash claims to be even faster and passes the SMHasher tests
- Since Rust 1.36 they switched from SipHash13 to https://github.com/rust-lang/hashbrown for hashmaps bdewater (Bart de Water)

03:52 PM Ruby Bug #20997 (Closed): YJIT panic assertion `left == right` failed: leave instruction expects stack size 1, but was: 2

I tried upgrading our Rails app from Ruby 3.3.6 to 3.4.1 and our test suite failed with the following panic error on our Linux CI runners. In case it matters, we use https://runs-on.com/ instead of GitHub's runners and the AMI name is `r... bdewater (Bart de Water)

03:05 PM Ruby Feature #19000: Data: Add "Copy with changes method" [Follow-on to #16122 Data: simple immutable value object]

Example from Sorbet which uses `with` as well:
``` ruby
class Point < T::Struct
const :x, Numeric
const :y, Numeric
end
# An immutable instance
Origin = Point.new(x: 0, y: 0)
right = Origin.with(x: 1.0)
