Testing story

Tested on Drone with an updated Drone image running Ruby 3. Also tested on adhocs both that this version of Ruby works on its own and that the update can be applied successfully to an existing server already running Ruby 2.7.

Deployment strategy

If everything goes entirely according to plan, this update should in theory require no manual intervention. We should plan to deploy this change on its own as a standalone deploy with the rest of the pipeline closed off in case anything doesn't go according to plan and we need to revert.

Follow-up work

Once all servers have been updated to Ruby 3, we can drop support for 2.7

We should quickly follow up this major version update with another update to pick up any patches that have come out since the upgrade work began.

Support for Ruby 3.0 ends in 9 months; end of March 2024. We should immediately begin preparing for an update to Ruby 3.1.
