We have released Psycopg 2.8.3, which includes a slight change to the logical replication.
Choosing the right frequency to send replication feedback messages from the client to the server was previously the developer's responsibility, with too many feedback messages being a waste of bandwidth and server resources, too few slowing down WAL cleanup and possibly preventing a server graceful shutdown.
We have just released Psycopg 2.8.2; a few days ago Psycopg 2.8.1 was released.
Some of the bugs addressed are ordinary teething problem with the 2.8 release, but an important change landed with 2.8.2: binary packages now ship with OpenSSL 1.1 instead of 1.0. This should fix concurrency problems on connection experienced both on Windows and Linux. Many thanks to Matthew Brett and Jason Erickson for this improvement!
After about two years from the previous major release, psycopg 2.8 is finally here!
Among the highlights, PostgreSQL errors are now mapped to Python exceptions for a more idiomatic way to handle them. Several additions allow a better insight of the connection status and query results.
Behind the scene, asynchronous communication and concurrency received several improvements, and dropping support for older versions of Python gave the chance to refactor and modernise the codebase (with the especial help from Jon Dufresne who ruthlessly butchered our code into a streamlined pulp).
Thank you very much to everyone contributing so far. Happy hacking!
psycopg2 version 2.7.5 has been released, fixing a few bugs found in the last months:
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 18.104.22.168. 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.
We have released psycopg2 release 22.214.171.124 as a new build of psycopg 2.7.3. The new build only affects the wheel packages and contains no change in the code.
The release 126.96.36.199 fixes psycopg2-wheels bug #2 which was in turn caused by auditwheel bug #80, resulting in incompatibility with glibc 2.26. The problem only affects Linux wheels users, it doesn't affect Windows, OSX, or user installing psycopg2 from source.
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).
Releasing psycopg2 version 2.7.2: a release fixing a host of bugs found in the last 3-4 months.
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).
