--- title: "Everything new in Ruby 3.2" publication: "Ruby Weekly" issue: 640 published_at: "2023-02-09" canonical_url: "https://rubyweekly.com/issues/640" --- Plus a huge list of Ruby meetups, a tiny Ruby release, and an Active Record test you can take. | #​640 — February 9, 2023 [Read on the Web](https://rubyweekly.com/issues/640) When I noticed we'd reached _issue 640_ I was reminded of the [fabled but unlikely](https://www.computerworld.com/article/2534312/the--640k--quote-won-t-go-away----but-did-gates-really-say-it-.html) quote of Bill Gates that _"640K ought to be enough for anybody."_ Is 640 issues of a newsletter enough for anybody? Probably. But, amazingly, the Ruby world seems to only be getting _busier_ lately, so I may have to defer such a decision to issue 1000.. 😁 __ _Peter Cooper, your editor_ Together with [![ButterCMS\](https://res.cloudinary.com/cpress/image/upload/c_fill,g_auto,e_trim,w_700,h_100/e_make_transparent/co_white,e_outline:10/h4j9v0v4af8ufqqreqfq.png)](https://buttercms.com/rails-cms/?utm_source=rubyweekly&utm_medium=email&utm_campaign=retirelegacycms) Ruby Weekly [![\](https://res.cloudinary.com/cpress/image/upload/w_1280,e_sharpen:60,q_auto/obdpwgjeym8ex9bhuhfi.jpg)](https://rubyreferences.github.io/rubychanges/3.2.html) [An Extensive Ruby 3.2 Changelog](https://rubyreferences.github.io/rubychanges/3.2.html) — Victor is back with another of his epic roundups of what's new in the latest version of Ruby.
