We just upgraded a site to 2.11.6. It has a native Date 1.0 field on a channel that generates invalid dates.
I get a validation error “The date you submitted is not valid.”
The entry gets published as expected.
So, it seems the calendar picker is generating two digit years but the form validation is expecting four digit years.
