SQLAlchemy version 0.4, the biggest release SQLAlchemy has ever had,
is released in its first beta.

If you haven’t been following along, it’s time to catch up ! An
overview-in-progress of whats new is at http://www.sqlalchemy.org/trac/wiki/WhatsNewIn04

And, quoting project’s leader:

We also desperately need beta testers for these platforms: MS-SQL, Firebird, and Informix. 0.4 has been tested extensively with SQLite, Postgres, MySQL, and Oracle.

New versions of SQLObject released: 0.7.8, 0.8.5, 0.9.1 full changelog is here.

SQLObject is an object-relational mapper for python. Your database tables are described
as classes, and rows are instances of those classes. SQLObject is meant to be
easy to use and quick to get started with.

This is a minor release that is primarily to fix a connection pool
issue revealed earlier today. The pool issue was introduced in 0.3.9
and did not exist in prior versions, and only affects the behavior of
“timeout”, nothing to do with the state integrity of the pool or its
connections. The release also fixes some small bugs involving
binding connections directly to MetaData as well as Sessions.

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL.

It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

Version 0.3.9 of SQLAlchemy is released.  This is probably not the last of the 0.3 series, but it’s the last major set of changes for this line; subsequent releases should probably be only for important bug fixes.  0.3.9 includes a lot of important bug fixes as usual, but also has a focus on the new API which is to be standardized in the upcoming 0.4 series, and is largely available in SQLAlchemy 0.3.9 so that existing applications can adapt to the new patterns.  These changes represent improvements by leaps and bounds over anything SQLAlchemy has ever had, and a lot of them are available right now.  The documentation has also been updated on the site with a large portion of these changes – so if you haven’t looked at SQLAlchemy’s documentation in a long time, now is the time to revisit; particularly the chapters on Database Engines, Database Metadata, and Data Mapping.

The 0.3 series is now coming in for a landing, foregoing shiny new bells and whistles which are instead skipping ahead in the 0.4 branch. Release 0.3.8 is primarily a bugfix release, with some new features of an only mildly spectacular nature.

Changes in the firebird engine:

• set max identifier length to 31
• supports_sane_rowcount() set to False due to ticket #370.
• versioned_id_col feature wont work in FB.
• some execution fixes
