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.
