+v1.11.2 (2025-02-10)
+--------------------
+This fixes two regressions:
+
+- Don't send startup parameters if there is no value, improving compatibility
+  with Supavisor ([#1260]).
+
+- Don't send `dbname` as a startup parameter if `database=[..]` is used in the
+  connection string. It's recommended to use dbname=, as database= is not a
+  libpq option, and only worked by accident previously. ([#1261])
