- Remove locking after code audit
- Documentation
- Factor out documentation into seperate file
- Add Quickstart to docs
- Add Bugs section to docs
- Add experimental tag to docs
- Add rclone provider to s3 backend docs
- Fixes
- Correct quirks in s3 backend
- Change fmt.Printlns into fs.Logs
- Make metadata storage per backend not global
- Log on startup if anonymous access is enabled
- Coding style fixes
