This is the final issue of 2022 as we're taking a break for Christmas. We usually finish off the year with a roundup but there's been enough news we're doing things a bit differently. The top half of this issue is the normal news, with some 2022 roundups following on. Happy holidays!

Rails Making Docker a First Class Option— Despite being an opinionated framework, Rails has generally been less concerned over how you deploy it, so it’s interesting to see effort placed into making it easy to run Rails anywhere containers are welcome via ‘Docked Rails.’ (I think an opportunity was missed to call it Whaleway..) Dockerfiles will also be coming by default in future versions of Rails.

Ruby on Rails Project

On the topic of Rails, Emmanuel Hayford has put together a vast array of developments leading up to an eventual Rails 7.1 release.

The State of Notifications Report - User Preferences— What is preventing us from designing a notification system that facilitates a better experience? Nobody wants to receive marketing notifications, but they are upset if they miss important notifications. We can do better.

RubyGems Introduces Hardware Security Token and Passkey Support— A way to keep gems secure is to ensure only the right people can publish new versions – now there are two new ways to ensure that. Once registered with RubyGems, a hardware token can be used as a second way to verify identity. Passkeys, built upon WebAuthn, provide a similar mechanism but without a separate physical device.
