A new version of PgBouncer, a lightweight PostgreSQL connection pooler, has been launched. PgBouncer 1.23.0 adds support for rolling restarts, user name maps for certificate and peer authentication methods, replication connections via PgBouncer, improvements to SHOW USERS output listing connections, and pool_size and server_lifetime configuration per database.

The minimum version requirement for c-ares has been raised to 1.9.0, and it now supports all address types in hba configuration.
