## Planned ahead
 ! Operation center must be able to create scheduled tasks for every operation
 ! Optional repo check before doing retention operations

## 3.0.0
 - This is a major rewrite that allows using multiple repositories, adds repository groups and implements repository settings inheritance from group settings

    - CLI operation center via `--group-operation --repo-group=somegroup`
    - Implemented retention policies
      - Optional time server update to make sure we don't drift before doing retention operations
    - Operation planifier allows to create scheduled tasks for operations
    - Implemented repo quick check / full check / repair index / repair snapshots / unlock / forget / prune / dump / stats commands
    - Implemented new housekeeping command which is a shorthand for check, forget and prune commands
  - Added per repo permission management
    - Repos now have backup, restore and full privileges, optionally allowing to restrict access for end users
  - Added snapshot tag to snapshot list on main window
  - Split npbackup into separate CLI and GUI
    - Status window has been refactored so GUI now has full stdout / stderr returns from runner and backend
  - Implemented file size based exclusion

  - New option --show-config to show inheritance in CLI mode (GUI has visual indicators)
  - Allow using external restic binary via --external-backend-binary parameter in CLI mode
  - Implemented stdin_from_command backup process which can now get exit codes of programs which output is backed up (ex: mysqldump)
  - GUI: Restore window is now faster
  - Prometheus metrics:
    - Metrics are now created for all types of operation
    - Metrics have npbackup execution state
  - Dry mode now works for all operations where restic supports dry-mode
  - Implemented scheduled task creator for Windows & Unix
  - Added --no-cache option to disable cache for restic operations (neeeded on RO systems)
