PgBouncer 1.20.0 has been released. This release deprecates the online restart feature using the -R flag, instead so_reuseport should be used for online restarts. It also introduces better support for tracking PostgreSQL settings using the new track_extra_parameters setting, which can be used to track search_path in combination with Citus 12.0+. It also adds some other features such as connecting using TLS by default, forwarding error codes in the authentication phase and support for the options startup parameter. And finally it also fixes a few minor bugs.
