Scottish Ruby User Group

About

The Scottish Ruby User Group is a collection of people who are linked with Scotland and have an interest in Ruby and Ruby on Rails.

We meet every month online and in person in Edinburgh for presentations from members and guests, and a chat about Ruby and related subjects.

All are welcome, and there are no subscriptions or costs involved.

Meetings are announced in advance on the mailing list, Meetup, and Google Group and follow our code of conduct.

You can also find us on:

Meeting up

We currently meet online on the second Thursday of the month at 18:00. Currently we’re experimenting with the most appropriate video conferencing solution. Links will be posted the day before if you’re signed up on Meetup.

Mailing List

You can browse and subscribe to the list using the ScotRUG Google Group information page. The list is for announcements of activities and general Ruby support and discussion; feel free to post any questions you may have.

IRC

We have a Freenode channel #scotrug, though it’s quite quiet. There’s also the Gitter channel around the ScotRUG github repository. It is also quiet.

Code of Conduct

To ensure we provide a welcoming and friendly environment for all, attendees, speakers, organisers, and volunteers at any ScotRUG meetup are required to conform to our code of conduct.

Organizers will enforce this code throughout the meetup and meetup-related social events.

Ruby 4.0 - What's in the new Release?

posted 04 Dec 2025

The shining lights of the Christmas markets sparkle through the crisp nights, signifying the impending arrival of a new Ruby version. This year’s release (scheduled for Christmas day) will be Ruby 4.0! Unusually, the major version number bump doesn’t mean underlying language or interpreter changes though. And if that’s intriguing, good!

It’s time for our usual December “what’s up with the new release?” chat, which we continue in the memory of Noah Gibbs. Noah was a member of the ScotRUG community, and used to work on YJIT.

Where and When?

We’ll be meeting on the 11th of December in the Quaker Meeting House on Victoria Terrace.

Agenda

  • 18:00 - meetup starts (social time!)
  • 18:30 - Ruby 4 discussion time! And if we run out of discussions - more general Ruby chat
  • 19:30ish - wrap up - decamp to pub/head home

What

For the discussion, we’ll likely break up into small groups. You can currently see the notes for version 4.0-preview2, and download the preview 2 to play around with. Have a look at the updated core gems, the release, and bring your thoughts.

There aren’t a huge number of obvious changes this year, so we’ll have plenty of time for general discussions too!

Sign up on Meetup, and we’ll see you there.
