Migration is currently not working for bug 1432338. From my tests, we exit here https://github.com/projectfluent/python-fluent/blob/babad8480a37ae30e80b5900cd76501fcefe5c2f/fluent/migrate/context.py#L358 I think that's because the resulting translated file is identical to English. If I change one string in the Italian file, the migration works as expected. This affects branding patches, but also en-GB as a locale. A workaround is to temporarily remove that check, but I'm not sure if there are other consequences. P.S. 'changeset' is misspelled in that comment

Note: there should likely be a warning in the console.

I think I did a dry-run for bug 1424683, but didn't realize nothing was migrated in the first case.

I know what's going on, taking.

Flagged you on gh as well. We'll likely want a dot release of python-fluent, and then carry that to m-c.

Comment on attachment 8950564 [details] link to PR lgtm! Thanks Axel!

The fix has landed and was released with python-fluent 0.6.3. It'll be deployed in m-c in bug 1437950
