1.1.0:

bug

[bug] [commands]

Fixed bug where the double-percent logic applied to some dialects such as \ 
psycopg2 would be rendered in --sql mode, by allowing dialect options to be \ 
passed through to the dialect used to generate SQL and then providing \ 
paramstyle="named" so that percent signs need not be doubled. For \ 
users having this issue, existing env.py scripts need to add \ 
dialect_opts={"paramstyle": "named"} to their offline \ 
context.configure(). See the alembic/templates/generic/env.py template for an \ 
example.

[bug] [py3k]

Fixed use of the deprecated “imp” module, which is used to detect pep3147 \ 
availability as well as to locate .pyc files, which started emitting deprecation \ 
warnings during the test suite. The warnings were not being emitted earlier \ 
during the test suite, the change is possibly due to changes in py.test itself \ 
but this is not clear. The check for pep3147 is set to True for any Python \ 
version 3.5 or greater now and importlib is used when available. Note that some \ 
dependencies such as distutils may still be emitting this warning. Tests are \ 
adjusted to accommodate for dependencies that emit the warning as well.

[bug] [mysql]

Fixed issue where emitting a change of column name for MySQL did not preserve \ 
the column comment, even if it were specified as existing_comment.

[bug] [setup]

Removed the “python setup.py test” feature in favor of a straight run of \ 
“tox”. Per Pypa / pytest developers, “setup.py” commands are in general \ 
headed towards deprecation in favor of tox. The tox.ini script has been updated \ 
such that running “tox” with no arguments will perform a single run of the \ 
test suite against the default installed Python interpreter.

usecase

[usecase] [commands]

The “alembic init” command will now proceed if the target directory exists \ 
as long as it’s still empty. Previously, it would not proceed if the directory \ 
existed. The new behavior is modeled from what git does, to accommodate for \ 
container or other deployments where an Alembic target directory may need to be \ 
already mounted instead of being created with alembic init. Pull request \ 
courtesy Aviskar KC.

misc

[change]

Alembic 1.1 bumps the minimum version of SQLAlchemy to 1.1. As was the case \ 
before, Python requirements remain at Python 2.7, or in the 3.x series Python \ 
3.4.

[change] [internals]

The test suite for Alembic now makes use of SQLAlchemy’s testing framework \ 
directly. Previously, Alembic had its own version of this framework that was \ 
mostly copied from that of SQLAlchemy to enable testing with older SQLAlchemy \ 
versions. The majority of this code is now removed so that both projects can \ 
leverage improvements from a common testing framework.
