 ### Obsoletions and obsolete API removals
 
+* The `Integrated Security` connection parameter has been removed. It was never actually necessary - simply stop setting it.
 * `NpgsqlTsVector.Parse()` and `NpgsqlTsQuery.Parse()` are now obsolete. These methods attempted to mimic the behavior of the PostgreSQL `to_tsvector` and `to_tsquery` functions, but could only do so partially and in problematic ways. Use the PostgreSQL functions instead.
 * The parsing functions on the built-in geometry types (NpgsqlPoint, NpgsqlBox etc.) have been removed; similarly, they partially replicated PostgreSQL parsing functionality client-side and had issues.
 * `NpgsqlLargeObjectManager` and `NpsgqlLargeObjectStream` are now obsolete. These types were very rarely-used, provided only a thin wrapper over easily-accessible PostgreSQL large-object functions, and limited usage in various ways (e.g. they didn't allow batching). Call the PostgreSQL large-object functions directly.
