Ruby 3.3.0-Rc1 Released

Anecdote: I'm personally pretty pleased with the development of Ruby over the past 5y. When I was in high school I picked up a O'Reilly book on RoR and thought to myself that this wasn't going to be a language that was going to be around when I was older. When I was in college I studied C/C++ and really looked down on it, seeing all the footguns and abstraction as a sign of weakness.

20y later (for me), it's still around and doing quite well for such a crowded space (high abstraction, general purpose languages). My company is one of the largest adopters of Ruby. Over the past 2y I've learned to love it and in some ways prefer it to Golang and Python. Godspeed Ruby team, thank you.

Ruby's not a language I hear that much about anymore yet still seems to maintain a very steady market share. Is it the huge existing Rails install base or new language features keeping it going? Is the Rails marketshare larger than Django?

This is RC1 so I wonder if Shopify, Discourse, GitHub or 37signals has any preliminary figures how much this speeds up their Rails application.

They don't elaborate enough how M:N scheduler is supposed to be used. Does it only work for ractors?

Nothing special here

”Ruby 3.3 adds a new parser named Prism, uses Lrama as a parser generator, adds a new pure-Ruby JIT compiler named RJIT, and many performance improvements especially YJIT.”
