News and Updates

Thanks to all who participated in this year's sprints at Pycon 2011. The releases of 0.6.7 and 0.7b4 owe a lot to what the group got done, including Pypy test coverage, unit test improvements, dialect fixes, lots of documentation tweaks and edits, some impressive ORM fixes, and other features. The sprints have also fostered an ongoing discussion on how we can keep the mailing lists diverse and increase the rate of communication - some website changes have already been made, including this blog, and more are in the works.

Beta 4 of SQLAlchemy 0.7 has been released. This is most likely the last beta of version 0.7 before final release. 0.7 has been downloaded many hundreds of times and a small series of regressions have been fixed; it is used in at least a few production installations already.

Of particular note in this release:

• Support for psycopg2, the Postgresql driver, on Python 3
• The C extensions now build by default for the Python 2 platform.
• Support for Python 3 builds using plain Python Distutils, or Distribute.
• Full test success for Pypy, Python 3.2
• Lots of bugfixes and revised documentation, including the new Revised index page.

0.7beta4 owes a lot to the sprinters at this year's Pycon; a subsequent blog post detailing the sprints for this year is coming soon.

The SQLAlchemy 0.7 series represents a great leap forward in functionality and performance - the upgrade path starts by reviewing the 07Migration document.

Changes can be reviewed at CHANGES; download SQLAlchemy 0.7beta4 on the download page.

SQLAlchemy release 0.6.7 is now available. This is a bugfix release to the 0.6 series, which is now mostly feature frozen. The 0.7 series has been the focus of new feature development for several months and is very near to production release - 0.6.7 represents all those bugfixes that were appropriate for a backport to the maintenance series.

The 0.6 series has been SQLAlchemy's most popular ever, with 0.6.6 alone logging over 52,000 downloads in just over three months.

For a full list of changes in 0.6.7, see CHANGES.

The first beta release of SQLAlchemy 0.7 is now available. This release features the past year's worth of new features, improvements, and usage patterns, including an all-new, unified event model, new extensions including so-called "hybrid" attributes as well as a new system of tracking changes on "mutable" scalar values, extensive performance improvements, new dialects, and a large number of other features and bug fixes. A full catalog of changes can be reviewed at 07Migration. Download SQLAlchemy 0.7 beta1 on the download page.

SQLAlchemy 0.7 is in active development and close to beta releases, featuring an all new unified event model as well as a host of other ORM and SQL engine features and improvements. The "Whats New" page for SQLAlchemy 0.7 is under construction at 07Migration.
