The last release (2.0.2) claims that the license is a ZPL, which is definitely “still a thing”. All 350+ packages in the zopefoundation GitHub organization are licensed under the ZPL, which is still an OSI-certified open source license. The current version is 2.1. The main issue I see in ExtFile is the lack of documentation how the license and copyright switch was done. In order to be considered for inclusion in the zopefoundation organization projects - if that’s your goal - some proof like a written statement of agreement to the license and copyright change from Gregor would be mandatory, and then written proof that Stefan Holek agrees to transfer copyright to the Plone Foundation. The rest, like the lack of an actual license file, is cosmetics and easily fixed. If those hurdles are too high no one can prevent you from creating a private fork and distributing it yourself, as long as you abide by the existing copyright and licensing provisions. jens
