### Fixed

- No longer broken JSON files including `\n`, during the bucket synchronisation. (#623)
- Custom headers and JWT tokens are now correctly sent to the server during configuration checking. (#624)

### Improved

- Bucket synchronisation has been enhanced for better performance and reliability.
    - Now less duplicated chunks are sent to the server.
    - Fetching conflicted files from the server is now more reliable.
    - Dependent libraries have been updated to the latest version.
