♪ EditiooOoOOnnN ! ♫

[lqd]

👋

The 2021 edition will become stable when 1.56 is released, on the 21st of october, and this draft PR prepares the playground to using it as the default edition after its release.

Specifically, I've:

• Set 2021 as the default in the UI.
• Removed the aside when setting the 2021 edition, as it will be available everywhere then.

I'm opening this PR as draft:

• I couldn't really test the server side, and would like CI to run tests for me.
• I wanted to ask for advice from Jake, in case I've forgotten other important steps and so on.
• this PR should probably only be merged in a month when 1.56 is released.

♪ Edition! ♫

One thing I think we should also add is a notification popup to let people know that 2021 is live and the default.

We should:

1. Remove the old notification
2. Add a notification for 2021

I don't have a great idea for the notification text or silence date, though.

[lqd]

Yes, indeed, good point about the notification. You had added one last time, for the 2018 edition, so I've used the same template. That one had a silence date of 01/01/2019.

Thanks for triggering CI as well, the integration tests should start passing on 1.56 IIUC.

Could you submit remove special case for cargo "edition2021" feature as a separate PR? That should be able to be merged before the next Rust release.

[lqd]

Sure, I've extracted the commit into #743 and removed it from this PR.

[shepmaster]

FWIW, I locally renamed beta to stable and ran the tests. I fixed up the failures and force pushed this branch.

Thanks @shepmaster 🙏
