Hi *,
this is probably one of the best psycopg releases ever. Daniele, Jason and all the others that sent patches did an impressive work to have psycopg build and work flawlessy on all the supported platforms (well.. we can probably do a little bit better on MacOS but everything else is almost perfect). So here it is (followed by NEWS excerpt, as always):

After a long while Psycopg has a Mailing List again!
You are welcome to subscribe, either if you are an user dealing with the first stumbling blocks (albeit a look at the documentation or the FAQ wouldn't hurt!) or if you want to contribute to the psycopg2 development, about which there are several upcoming news.

PostgreSQL notifications with Psycopg2 and Eventlet

notify
PostgreSQL supports asynchronous notifications, a simple messaging system allowing clients to be notified about events occurred in the database. Notifications can be sent by any session using a "NOTIFY channel" command and will be received by any session which has subscribed with a LISTEN channel to receive updates. The system has been greatly improved in PostgreSQL 9.0 with the addition of a message payload, making the feature even more useful. Previously a typical use case would have been to notify interested sessions that a certain table was updated: now it is possible to signal for instance which record was changed. You can put the NOTIFY command in a database trigger for automatic notifications on insert or update... the possibilities are actually quite interesting.

Hi *,
lately my involvement on psycopg has been quite small (work and other projects are taking their toll) but thanks to Daniele (with some help from Jan) here is a new psycopg2 release. The number of changes is big (an excerpt from the NEWS file is at the end, as always) so we decided to bump up the version to 2.3.0 and to test, and test... and test. We tested this new release on Linux and Windows, with Python 2.4, 2.5, 2.6, 2.7 and on PostgreSQL from 7.4 to 9.0.
