SQLAlchemy release 1.0.1 is now available.

This is a quick bug-fix release that repairs several new regressions identified in the 1.0.0 release, not found during the beta period. All users of 1.0.0 are encouraged to upgrade to 1.0.1.

Key elements of this release include fixes regarding the NEVER_SET symbol leaking into queries in some cases, fixes to SQLite when using DDL in conjunction with referential integrity enabled, a fix to the EXISTS construct which primarily impacts queries that use special datatypes, and repairs to the Firebird dialect regarding the new LIMIT/OFFSET features.

In order to accommodate some of these fixes, there are three additional behavioral changes in 1.0.1; a new warning is emitted when using DDL with SQLite in conjunction with mutually-dependent foreign keys (e.g. a reference cycle), a new warning is emitted when running ORM relationship comparisons when the target object contains the value None for any of the Python-side column values, and a change is made regarding which data values are used within a relationship comparison that uses the != operator, in order to make the behavior consistent with that of the == operator as used in the same context. The migration notes contains updates for all three of these changes, and they are each linked directly from the changelog which should be carefully reviewed.
