Version 3.1.0

Changed

- Increase resilience against IMAP errors. Added an option `--[no-]skip-errors`, which
  is enabled by default, but can be disabled to error out on IMAP folder errors.

Version 3.0.1

Changed

- Updated dependencies.

Fixed

- Docker image now works again for real (finally fixes #10?).

Version 3.0.0

Changed

 - **BREAKING:** Removed the `-v`/`--verbose` switch which was not functional
   anyway and added a new option `-O`/`--log-output` flag to write IMAP responses
   to a file in JSON format.

Version 2.1.0

Added

- New command-line flag `-l`/`--limit` to limit the statistics output to
  a given number of mailboxes (folders).

Version 2.0.1

Fixed

- Do not crash with empty IMAP mailboxes.

Version 2.0.0

Added

- `stats` command: Added new option switch `-H`/`--human`.
- `stats` command: Added new option switch `--reverse` to reverse the sort
  order.

Changed

- **BREAKING:** Message sizes are now output in bytes by default. This also
  applies to CSV output. Use the new `-H`/`--human` switch to convert byte
  counts to SI-prefixed numbers.
- **BREAKING:** The sort properties `q1` and `q3` have been renamed to `q1_size`
  and `q3_size`.
- Output: Draw table borders in blue for better visual separation.
- Output: Draw a separator line above the 'total' row.
- Updated dependencies.

Fixed

- `stats` command: Sort did not work at all.
- Do not crash when collecting stats for mailboxes with a very large number of
  messages. Closes Github issue #8.

Removed

- **BREAKING:** Removed the `-O` switch to reverse the sort order as it did not
  work as intended
