SQLAlchemy release 1.1.7 is now available.

Release 1.1.7 includes several bugfixes, one of which was introduced in 1.1.6 as a result of performance enhancements for joined eager loading which presents as a race condition under certain multithreaded scenarios. Fixes also include an important adjustment in the cx_Oracle dialect to adjust for changes in cx_Oracle release 5.3, resolution of an extremely small memory leak which could occur in the relatively unusual case that an arbitrarily high number of savepoints were established on a single Connection object, as well as an important fix in the "schema translate" feature.
