SQLAlchemy release 0.9.5 is now available.

0.9.5 contains mostly bug fixes as well as some smaller enhancements, and the first to be alongside new features and refactorings going into the 1.0 release branch. While the issue queue still has a handful of critical fixes to go, it's been several months since a release so the current crop of fixes and small enhancements within 0.9.5 is due to go out. 0.9.6 should be following within the coming weeks.

SQLAlchemy had a big year at this year's Pycon North America presented in Montréal, Canada. Conference presentations were given by three separate speakers, and a three hour tutorial session was given as well. Videos and supporting documents are now available in the new SQLAlchemy Library, a new site section where we're gathering every kind of learning resource we can for SQLAlchemy in one place.

Links to talks:

• Building the App - Mike Bayer
• Sane Schema Migrations with Alembic and SQLAlchemy - Selena Deckelmann
• Introduction to SQLAlchemy Core- Jason Meyers

This year's tutorial was a replay of Introduction to SQLAlchemy, the intro tutorial that's been presented at many conferences.

SQLAlchemy release 0.9.4 is now available.

0.9.4 contains mostly bug fixes, split across regressions local to 0.9 as well as more general issues. There are also some new features, in particular a major change to the testing system to support py.test in addition to nose.

Many bugfixes have also been backported to the 0.8 series which is being released simultaneously as 0.8.6, however others are being left only in 0.9 as they represent a slightly bigger change in behavior; the changelog will note which issues are backported and which are not. Key fixes include an enhancement to the mechanics of connection pool recycling to be more efficient as well as tweaks to event mechanics.
