Released: August 30, 2021

bug

[bug] [installation] Corrected "universal wheel" directive in setup.cfg so that building a wheel
does not target Python 2. The PyPi files index for 1.7.0 was corrected
manually. Pull request courtesy layday.

[bug] [pep484] Fixed issue in generated .pyi files where default values for Optional
arguments were missing, thereby causing mypy to consider them as required.

[bug] [batch] [regression] Fixed regression in batch mode due to #883 where the "auto" mode
of batch would fail to accommodate any additional migration directives
beyond encountering an add_column() directive, due to a mis-application
of the conditional logic that was added as part of this change, leading to
"recreate" mode not being used in cases where it is required for SQLite
such as for unique constraints.
