After a few stumbling blocks, I have a branch of Discourse that runs on Ember 2.4. Our goal for the next major Discourse release is to upgrade to the latest Glimmer 2 technology which has many performance improvements, and Ember 2.4 is a big step towards that.
I’ve deployed the branch here to meta Discourse, so we’d love it if you could report any issues you encounter. It would be especially helpful if plugin developers could check out the branch and try their plugins against it so that we can identify any regressions well in advance.
2.4 unfortunately has deprecations on
Ember.View classes, so I will be spending the next chunk of time converting the last few Ember views to be components. So far I have been doing all the deprecation work in parallel, so it is compatible with both Ember 1.11 and Ember 2.4, but once this is done I plan to continue from 2.4 onwards in master.
Thanks for your help!
