No, this is not a deja-vu. The last release brought you imports of translation templates from Bazaar branches, now you can import your actual translations too.
Enabling import of translations (usually called PO files) seems to be the logical next step since the import of translation templates (usually called POT files) is already in place.
There are a few scenarios in which this would be useful, but I think the most common is likely to be the initial import of translations when you start using Launchpad Translations for a project that already has translations. For this purpose I added the “Request Bazaar import” option right next to “Settings” on the menu bar of your project’s release series. Here you can request a single import of all translation files (templates and translations) that are in the branch. Just click on the button and wait for your files to show up in the import queue. You need to have an official branch linked to this release series in order to see this button.
If you have reasons for letting Launchpad continuously import both translation templates and actual translations from your branch you can set this up on the “Settings” page. Choose “” to initiate an initial full import of all files and subsequent imports of changed files into Launchpad Translations.
The approval of translation files after they are uploaded works just as if they were uploaded through the upload form. To be sure that they are automatically and quickly approved and imported place them in the same directory as the template file they refer to and name them after the approriate language code, e.g. es.po for Spanish translations.
I hope you can make good use of the feature. Next up will probably be exporting translations back into your branch. Doesn’t that sound cool?
