Can we wait for #474 before doing the release? Since the fix will be a breaking change (which also means fix should wait for the workshop lol).

We can do multiple pre-releases as needed. Prereleases can break the interface still. Do we really need to wait for #474 ?

Sure, but it does take time (even if non significant). I don't see any benefit of doing a pre-release now, but it's up to you.

@kt474 we promised one this week, so let's not hold up.
