Psycopg 2.7.4 released

We have released Psycopg version 2.7.4, bringing a few bug fixes... and working out the problem with Wheel packages.

Following the release of PostgreSQL 10 we have released new binary packages as Psycopg 2.7.3.2. There are no code changes from Psycopg 2.7.3, but the new binary packages ship with the PostgreSQL 10 client library, enabling the use of new features such as multiple hosts in connection string, read-only mode, SCRAM-SHA-256 authentication.

Psycopg 2.7.3 released

A quick release to fix a regression found in psycopg 2.7.2:

Restored default timestamptz[] typecasting to Python datetime. Regression introduced in Psycopg 2.7.2 (ticket #578).

Psycopg 2.7.2 released

Releasing psycopg2 version 2.7.2: a release fixing a host of bugs found in the last 3-4 months.

Psycopg 2.7.1 released

A quick bugfix release to solve some teething problems with some of the changes introduced in 2.7:

Ignore None arguments passed to connect() and make_dsn() (ticket #517).
OpenSSL upgraded from major version 0.9.8 to 1.0.2 in the Linux wheel packages (ticket #518).
Fixed build with libpq versions < 9.3 (ticket #520).

Psycopg 2.7 released

Finally here! Thank you very much for waiting so long: we have finally released Psycopg 2.7!

Buzzwords:

Faster! Helps generating SQL for repeatedly executed statements and faster Unicode decoding.
Safer! Helps generating dynamic SQL statements with variable table and field names.
Easier! Use the binary package to avoid the need of C compiler, pg_config, libpq required on the clients.
Replication! Support for PostgreSQL physical and logical replication.

Psycopg 2.7 beta 2 released

Hello,

we have released psycopg2 version 2.7 beta 2. This version comes two years after the previous major release so it is packed with new features and improvements; among the main points:

support for replication protocol
helpers to build dynamically SQL statements and manipulate connection strings
speedups in multiple execution and Unicode decoding
better transactions characteristics support

A more complete list of changes is available at http://initd.org/psycopg/docs/news.html#what-s-new-in-psycopg-2-7

On top of the changes in the code we have addressed the deployment problems found my many inexperienced users, especially on Windows and OSX: psycopg is now distributed as a self-contained wheel package on PyPI, so that:

pip install psycopg2

will not require the presence of C compiler, headers, pg_config, libpq.

Because of all these changes, we ask you kindly to test this psycopg beta release, both its installation and its usage, before we release the stable version, which should happen next week if we don't find any problem. The binary packages of the beta release are on the PyPI testing site: you can install it using:

pip install -U pip # make sure to have an up-to-date pip
pip install -i https://testpypi.python.org/pypi psycopg2==2.7b2

Thank you very much everyone, and I wish to thank especially Oleksandr Shulgin and Craig Ringer for the development of the replication protocol support (the development of which brought along several other features and improvement) and Jason Erickson for the invaluable help with the Windows packages.

Happy testing!
