NOTE: The next major release of jamJAR will work only with Munki's shipping Python 3 & will also officially support Apple updates via Munki & the new workflows in Munki 5 (https://github.com/munki/munki/wiki/manual-apple-updates-in-Munki-5).

Reverted the below, as s Munki will not always publish category to ManagedInstallReport.plist when an item is installed.

• #13 - added the "no_msg_category" key. Items with this category will not post notifications (see https://github.com/dataJAR/jamJAR/wiki/jamJAR-Preferences#no_msg_category)
