Replaces and combines the former packages mkp_cleanup and mkp_updates (MKP Updates) in one package. Keeps a site's extension packages (MKPs) current and tidy:

• mkp-update (command line) finds newer versions of installed packages, downloads and verifies them, and installs them after asking, or automatically.
• MKP Updates (special agent + check) reports the same as a Checkmk service: which packages have an update, which can't be checked.
• mkp-cleanup (command line) finds outdated and duplicate package versions and disables or removes them.

Local MKP repository: put the MKPs your organization has tested and approved into a directory (file share, git repository) or onto an internal web server; mkp-update and the MKP Updates service use it, also on sites without internet access (--offline). Otherwise updates are looked up via each package's Download-URL (GitHub, GitLab, Gitea, any git server) or the Checkmk Exchange.

Run the tools as the site user, e.g. via omd su SITENAME.

Upgrading from mkp_cleanup or mkp_updates: Checkmk refuses to enable this package while one of them is still enabled. Run the migrate-to-mkp-maintenance script from the release once - rules, services, sources file and cron jobs keep working (see the README).

I did not develop this MKP officially as an employee of Checkmk GmbH, but rather as a private individual.
