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.

PgBouncer is a lightweight connection pooler for PostgreSQL.
