- **lcc top-suites**: show the number of tests per suite
- **CLI**: on multiple commands, the console styling was not turned off when the output got redirected
- **CLI**: fix `lcc` crash when no command is passed (Python 3 only)

CLI breaking changes

- the following command arguments have been dropped:
- **lcc fixtures**: `--color`, `--verbose`
- **lcc show**: `--no-metadata`, `--short`, `--flat-mode`, `--color`
- **lcc stats**: `--color`
- **lcc show**: `--desc-mode` has been renamed into `--show-description`

- **under the hood**: improve task management, make it more robust and code cleaner
- **lcc version / lcc -v**: show the Python version in use

- Fix `lcc run --save-report at_each_failed_test` (also the default value for `--save-report`) that saves the report at
each successful test instead of each failed test (regression introduced in 0.22.0)

- Fix `suite_teardown` & session/suite fixtures teardown called as soon as a test fails in a suite while other tests remain to be executed (regression introduced in 0.22.2 while trying to fix teardowns not being called at all)

- Fix fixture (with scope > test) and suite teardowns not being called in case of failed test in a suite (bug was introduced in 0.19.0)

- **lcc report**:
- various visualization improvements
- add a `--explicit` argument to make some indicators understandable even without color codes
- add a `--max-width` argument to manually control the maximum width of tables
