We have a new version out, v0.1.2, in order to accommodate further changes required by the WordPress Plugin Review team. You can download it here:
mailbard-newsletters-0.1.2.zip
Unfortunately among the changes we had to remove all the old MailPoet translation files. So we’ll have to make new translations at some point. 🙁 (Hopefully we can salvage something from the old MailPoet .mo files?)
