Since 4.1.0 we have made many minor and patch releases during preparation for another Snowstorm milestone.
I am very pleased to announce that we have now gone live with Snowstorm as the Terminology Server for the SNOMED International Edition Authoring Platform!

As usual we have also had plenty of engagement from the community with many questions, issues and pull requests coming through. Thank you.

Please note the new approach to importing and upgrading extensions. The Code System migrate function is now deprecated in favour of the new upgrade function.
Code System branches should be created directly under MAIN rather than under a version branch. For example MAIN/SNOMEDCT-US.
Using the upgrade function Snowstorm will rebase the Code System branch to the a specific point on the timeline of the parent branch where the requested version
was created, without having to use release branches like MAIN/2019-07-31.

I hope you find this release useful and as always please just reach out or raise an issue if you have questions.

Features

  • New approach to upgrading extensions using Code System upgrade function. (Migrate function now deprecated).
