Psycopg is the most popular PostgreSQL adapter for the Python
programming language. At its core it fully implements the Python DB
API 2.0 specifications. Several extensions allow access to many of the
features offered by PostgreSQL.
Psycopg 2.4 beta1 has been released. The most important features in
this version are:
- the long due support for Python 3
- support for PostgreSQL composite types
- more efficient iteration on server-side cursors
plus a bunch of optimizations and bug fixes: you can find all the
details in the announce at
<http://initd.org/psycopg/articles/2011/02/06/psycopg-24-beta1-released/>.
A final release is planned in a few days. If your program was ready
for Python 3 and just needed a way to connect to PostgreSQL, this is
the time to test it. For any feedback you are welcome on the project
mailing list or issue tracker.
