We are immensely proud to release on PyPI
<https://pypi.org/project/psycopg/3.0b1/> the first beta package of Psycopg
3 <https://www.psycopg.org/psycopg3/docs/>!

Psycopg 3 is a complete rewrite of Psycopg 2, maintaining the same
fundamental libpq wrapper architecture and DB-API interface design, but
exposing new features to better work with the newer versions of Python and
PostgreSQL.

On the Python side, Psycopg 3 allows the use of asyncio-based concurrency
and static typing. Many improvement to the Python interface make the
library much simpler and more idiomatic to use,

On the PostgreSQL side, Psycopg 3 makes use of server-side parameters,
prepared statements, binary parameters, and great support for COPY
operations.

But the most outstanding feature of the project is not a technical one:
Psycopg 3 was made possible by the great generosity of many sponsors
<https://www.psycopg.org/sponsors/>, who have funded the development of the
project. Among the many backers, we are especially grateful to Postgres
Professional <https://postgrespro.com/> and Command Prompt, Inc
<https://www.commandprompt.com/>., which have given the most outstanding
support. But many other companies and individuals, each one in their
capacity, have shown concrete support for free software development and
progress. We sincerely hope that you will find this work useful and that
you will feel proud for having contributed to it.

Where do we go from here? The hope is that the interface of the adapter
will not change excessively before a definitive 3.0 release: the project
has already been used in a few production environments, in the past months,
and a lot of real world feedback has already helped to improve the
interface and functionalities. We invite you to test the project and give
us your feedback. So...

    pip install -U pip
    pip install --pre psycopg[binary]

Please try it, test it, and let us know how it goes!

For more info you can dive into the docs: start from the install
<https://www.psycopg.org/psycopg3/docs/basic/install.html> and usage
<https://www.psycopg.org/psycopg3/docs/basic/usage.html> pages, I'm sure
you will find your way.

Happy hacking!
