This behavior wasn't documented and didn't fully work: it breaks as soon as you try to save a model with a
None
value.I think removing
None
support is better than making it work:null
constructor argument both in the implementation and in the type checking, which is a lot of worknull=True
for text fields, so the value of the feature is questionableAs it was an undocumented feature that only partially worked, I think this change doesn't break backwards compatibility, so I didn't add it to the ChangeLog.
