X-Last-Upgrade-Packager-Version (wpkg-status)

The X-Last-Upgrade-Packager-Version field defines the version of the package used the last time this package was upgraded. This is important if we ever get some unreasonable incompatibility between versions and you need to check what version did what to your installation before it can get fixed as expected.

Note that this field is not defined unless the package was upgraded.

This version is the same as the version printed out when you run this command:

wpkg --version
