 The YugabyteDB [YSQL API](../../api/ysql/) reuses a fork of the PostgreSQL [query layer](../../architecture/query-layer/). This architecture allows YSQL to support most PostgreSQL features, such as data types, queries, expressions, operators and functions, stored procedures, triggers, extensions, and so on - all of which are expected to work identically on both database systems.
 
-Initially based on PostgreSQL 11.2, YSQL has been continuously enhanced with features, improvements, and security fixes pulled from PostgreSQL 12+, in addition to our own improvements. With {{<release "2.25">}}, YugabyteDB now adds support for PostgreSQL 15, which brings many new features and improvements.
