- Improved import-posts command. Now it supports media attachments and doesn't create duplicate posts if executed multiple times.
- Login page can be translated. The language is selected automatically based on browser settings.
- Moved visibility selector to the right side of the post editor (now it's near the "Publish" button). This is to minimize the likelihood of inadvertently publishing a post with a wrong visibility setting.
- Implemented Media Upload API for FEP-ae97 clients.
