- **Breaking**: MDII uploader
### Changed
- **Breaking:** Pleroma won't start if it detects unapplied migrations
- **Breaking:** attachments are removed along with statuses when there are no other references to it
- **Breaking:** Elixir >=1.8 is now required (was >= 1.7)
- **Breaking:** attachment links (`config :pleroma, :instance, no_attachment_links` and `config :pleroma, Pleroma.Upload, link_name`) disabled by default
