Closes #1817
This makes it so that newly added columns are
NULL
by default, instead ofNOT NULL
except in the case of a column that uses theidentity
option, and does not also set anull
option.This is definitely BC breaking, and the release notes should make a big note that all previously written migrations will have to be updated to take into account the new null default, unless the authors were already explicit about the null status within their migrations.
