Fixed:

- Internal documents are now ignored.
- Merge dialogue now respond immediately to button pressing.
- Periodic processing now works fine
- The checking interval of detecting conflicted has got shorter
- Replication is now cancelled while cleaning up
- The database locking by the cleaning up is now carefully unlocked
- Missing chunks message is correctly reported

New feature:
- Suspend database reflecting has been implemented
- Now fetch suspends the reflecting database and storage changes temporarily to improve the performance.
- We can choose the action when the remote database has been cleaned
- Merge dialogue now show `↲` before the new line.

Improved:
- Now progress is reported while the cleaning up and fetch process
- Cancelled replication is now detected
