PgBouncer 1.22.0 has been released. The main feature this release adds is support for the `DISCARD ALL` and `DEALLOCATE ALL` commands when enabling prepared statement support in transaction pooling mode (by setting `max_prepared_statements` to a non-zero value). This is an important improvement in the prepared statement support that clears the road for us to be able to enable prepared statement support by default in a future release.
Other than that this release contains some small improvements and bugfixes, including improvements to our recommended SystemD configuration files. See [https://www.pgbouncer.org/2024/01/pgbouncer-1-22-0](https://www.pgbouncer.org/2024/01/pgbouncer-1-22-0) for more information, the detailed changelog, and download links. PgBouncer is a lightweight connection pooler for PostgreSQL.
