Psycopg 3.0 released

Hello,

I am extremely excited to announce the first stable release of Psycopg 3

Psycopg 3 is a complete rewrite based on the experience accumulated with
the development and maintenance of psycopg2. Psycopg 3 targets all the
current versions of Python (3.6-3.10) and PostgreSQL (10-14) and allows the
use of modern Python development techniques, such as async and statically
typed code. A list of the new features
<https://www.psycopg.org/psycopg3/docs/> is available in the documentation.

This was a long journey: I would like to thank the people who have helped
to make this project amazing with their ideas and their code: Denis Laxalde
(row factories), Daniel Fortunov (transaction blocks), Jacopo Farina
(PostGIS support) and many who have tested, helped, discussed, cheered for
us.

And an immense thank you to the sponsors who have made this project
possible: Postgres Professional <https://postgrespro.com/> and Command
Prompt <https://www.commandprompt.com/> have been our biggest supporters so
far, but many companies and individuals <https://www.psycopg.org/sponsors/>
have given their generous contribution. Surely there will be more work to
come in the future: if you want you can help sponsoring the project
<https://github.com/sponsors/dvarrazzo/> too.

If you would like to try out the project please check out the Installation
and usage instruction
<https://www.psycopg.org/psycopg3/docs/basic/install.html>. We are eager to
hear your feedback and to share this journey with you.

-- Daniele, on behalf of Psycopg
