In order to fix deprecation warnings on Python 3.12 (see #72), this release removes support for legacy and meanwhile EOL versions of:

• python2
• pywbem 0.7.0

Meanwhile every still running and active system should run Python3.

If your monitoring system doesn't, don't update and remain on plugin version 20221230.

This release fixes a bug (issue #68), when no serial number was presented by the CIM elements. The plugin will now show a s/n: None in the output, if no serial number was detected.

This release adds two new parameters --format and --pretty to the plugin. JSON output is now supported. This is required when using the plugin with Zabbix.
