Release Notes

emberjs/ember.js (ember-source)

v6.12.0

Compare Source

• #​20908 / #​21020 Merge glimmerjs/glimmer-vm into the emberjs/ember.js monorepo.
  • All @glimmer/* packages that were formerly dependencies of ember-source are now included in the monorepo. This enables us to more easily iterate
    on the Glimmer VM and related packages, avoid an integration step with ember.js and to more easily share code between them and ember-source.
  • Only a few of the packages from the glimmer-vm repo will continue to be published as separate packages, for example, @glimmer/syntax will be published.
  • The glimmer-vm repo has been archived and relevant issues have been moved to the emberjs/ember.js repo. If you have an issue that was not moved, please reopen it on ember.js, after a search.
