EDIT: 1.5.1 released, removing the option to not post notifications for items with a category due to the category not always being written to the ManagedInstallReport.plist when installed. A PR to Munki will be needed to resolve, then this can be re-added.
Tonight brings an update to jamJAR. This update adds an option to not post notifications for items with a category & also adds support for the forthcoming dataJAR Notifier.app (to post banner & alert notifications as needed).
This is the last Python 2 release of jamJAR, the next release will utilise Munki’s shipping Python 3 & will also officially support Apple updates via Munki & the new workflows introduced Munki 5.
