 ### Features
 * Unmarshal AGE result data(AGType) to Vertex, Edge, Path
-* Cypher query support for Psycopg2 PostgreSQL driver (enables to use cypher queries directly)
+* Cypher query support for Psycopg3 PostgreSQL driver (enables to use cypher queries directly)
 
 ### Prerequisites
 * over Python 3.9
