### New Feature

- Now, we can send custom headers to the server.
- Authentication with JWT in CouchDB is now supported.

### Improved

- The QR Code for set-up can be shown also from the setting dialogue now.
- Conflict checking for preventing unexpected overwriting on the boot-up process has been quite faster.

### Fixed

- Some bugs on Dev and Testing modules have been fixed.
