Ruby 3.2.0 Released — It’s here! As is the tradition, the latest release of Ruby arrived on Christmas Day (but we took a couple of weeks off). 3.2 is from another dimension, allegedly, and packed with lots of cool stuff:
- The
Dataclass is a new core class for representing simple immutable value objects. It was originally proposed by Victor Shepelev who has written about its design here. - YJIT is no longer experimental and, as we'll see later, yields a nice performance boost in numerous scenarios.
- An initial level of WASI-based WebAssembly support. Ruby running on WASM-based serverless platforms? Yes. Running in the browser? Yes. Expect to see more of this in 2023.
- As part of the WASM support, there's a VFS built on top of WASI so apps can be packed into a single
.wasmfile. - Extra protections against inefficient regexes, including
Regexp.timeout - Improved error highlighting and suggestions.
- Anonymous rest and keyword rest arguments can be passed as arguments.
- The find pattern is no longer experimental.

Be Careful with Time Durations in Rails — ActiveSupport offers some great time and date helpers, like 3.months.from_now, but they can surprise you (in a bad way) if you’re not aware of how they work, so start the new year by handling months correctly.
