1.12.0

Released: August 31, 2023

feature

[feature] [autogenerate] Added new feature to the "code formatter" function which allows standalone
executable tools to be run against code, without going through the Python
interpreter. Known as the exec runner, it complements the existing
console_scripts runner by allowing non-Python tools such as ruff to
be used. Pull request courtesy Mihail Milushev.

[usecase] [autogenerate] Change the default value of
EnvironmentContext.configure.compare_type to True.
As Alembic's autogenerate for types was dramatically improved in
version 1.4 released in 2020, the type comparison feature is now much
more reliable so is now enabled by default.

[bug] [operations] Added support for op.drop_constraint() to support PostrgreSQL
ExcludeConstraint objects, as well as other constraint-like objects
that may be present in third party dialects, by resolving the type_
parameter to be None for this case. Autogenerate has also been
enhanced to exclude the type_ parameter from rendering within this
command when type_ is None. Pull request courtesy David Hills.

[bug] [commmands] Fixed issue where the revision_environment directive in alembic.ini
was ignored by the alembic merge command, leading to issues when other
configurational elements depend upon env.py being invoked within the
command.

[bug] [autogenerate] Fixed issue where the ForeignKeyConstraint.match parameter would not be
rendered in autogenerated migrations. Pull request courtesy Asib
Kamalsada.
