SQLAlchemy 0.9.9 Released

permalink

SQLAlchemy release 0.9.9 is now available.

Release 0.9.9 is a large maintenance release featuring 30 changes, mostly bug fixes. A handful of modest feature adds are also present, including new Core features for SQLite, Postgresql, and new API features to provide better control of transaction isolation level when using the ORM.

The majority of SQLAlchemy development is taking place targeted at version 1.0, which is extremely close to having its initial beta releases. Version 1.0 has accumulated a wide variety of performance improvements, both as intrinsic to normal operation as well as via new features.

Users should carefully review the Changelog to note which behaviors and issues are affected. We'd like to thank the many contributors who helped with this release.

SQLAlchemy 0.9.8 Released

SQLAlchemy release 0.9.8 is now available.

As the 1.0 series is well underway, 0.9.8 continues to close out bugs that can still be applied without significant risk of destabilization. In contrast to 0.9.7 where we were still hitting upon regressions, 0.9.8 fixes a set of garden variety bugs, many of which are related to changes in DBAPIs (new SQL Server version strings, new Psycopg2 error conditions, changes in MySQL-connector-python and pg8000). That being said, 0.9.8 has a relatively large amount of fixes overall.

Users should carefully review the Changelog to note which behaviors and issues are affected. We'd like to thank the many contributors who helped with this release.

SQLAlchemy 0.9.7 Released

SQLAlchemy release 0.9.7 is now available.

The 0.9 series is now entering maintenance mode where major new features are now targeted at the 1.0 series. Release 0.9.7 contains a wide range of bugfixes, many of which are identified as regressions from previous 0.9.X releases including three introduced in 0.9.5. All relevant fixes are of course forwards-ported to the 1.0 series and a handful are also backported to 0.8.7, being released at the same time.

A small number of new features include Postgresql JSONB support, improved Postgresql text matching features and a new event hook which allows database exceptions to be intercepted and re-thrown as new ones.

Users should carefully review the Changelog to note which behaviors and issues are affected. We'd like to thank the many contributors who helped with this release.
