News and Updates

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.

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 release 0.8.6 is now available.

Release 0.8.6 contains a variety of bugfixes backported from the 0.9 series. Areas of fix include ORM issues as well as dialect-specific issues.

That's not your eyes playing tricks on you, the SQLAlchemy logo is now a little bigger. Today, some modifications to the site layout have gone out, including some new fonts, updated navigation, and an all new section called The Library. The Library is the new home base for all kinds of documentation, blog posts, and videos about all things SQLAlchemy. The same old documentation links are right at the top, but beyond that there's links to the Architecture of Open Source chapter, links to Pycon talks as well as whatever else was handy. We'd like users to be aware of the very best of SQLAlchemy documentation resources so be sure to check back with the Library every now and then for new additions.

SQLAlchemy release 0.9.3 is now available.

Release 0.9.3 includes a wide array of bugfixes and a few new features. A critical subset of these fixes are also backported to release 0.8.5. Both 0.9.3 and 0.8.5 are being released simultaneously to resolve a concurrency-related regression introduced in version 0.8.4, which can cause a dialect to sporadically be used in a mis-configured state when it first connects. For this reason, 0.9.3 is recommended for all users of the 0.9 series.

Other improvements include updates to the Postgresql dialect to better handle schema reflection when working with old versions of Postgresql, namely pre-0.8.1 versions, which should also have a positive effect on those users using Amazon Redshift. 0.9.3 also includes improved support for SQLite type reflection, using SQLite's "type affinity" rules to unconditionally reflect all possible datatypes declared within a database.

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.
