PgBouncer 1.14.0 is out. This release contains several significant enhancements.
Encrypted SCRAM secrets in PgBouncer can now be used for server-side login, so storing plain-text passwords in PgBouncer is no longer necessary to be able to use SCRAM. The systemd integration has been enhanced to support socket activation. Also, PgBouncer now supports Unix-domain sockets on Windows, matching the new capabilities of PostgreSQL 13.
