:paramref:`.MetaData.naming_convention` feature will now also
apply to :class:`.CheckConstraint` objects that are associated
directly with a :class:`.Column` instead of just on the
:class:`.Table`.
- Added a new feature :func:`.schema.conv`, the purpose of which is to
mark a constraint name as already having had a naming convention applied.
This token will be used by Alembic migrations as of Alembic 0.6.4
in order to render constraints in migration scripts with names marked
as already having been subject to a naming convention.
re: #2991
- add more support for suite tests, moving some tests from test_query out to suite
and adding some more requirements
- add a suite test for underscore as initial char
comment
- move some requirements up to the testing module to better support running
SQLA internal tests outside; plus things like savepoints, twophase
- Added support for literal rendering of boolean values, e.g.
"true" / "false" or "1" / "0".
- added Boolean tests to the test suite
- correct this to make the intention clear
- fairly epic rework of the cascade documentation
- Added support for the not-quite-yet-documented ``insert=True``
flag for :func:`.event.listen` to work with mapper / instance events.
typo
- Improved an error message which would occur if a query() were made
against a non-selectable, such as a :func:`.literal_column`, and then
an attempt was made to use :meth:`.Query.join` such that the "left"
side would be determined as ``None`` and then fail.  This condition
is now detected explicitly.
