+The column `propertyTypes` currently returned by the procedures link:{neo4j-docs-base-uri}/operations-manual/{page-version}/procedures/#procedure_db_schema_nodetypeproperties[`db.schema.nodeTypeProperties()`] and link:{neo4j-docs-base-uri}/operations-manual/{page-version}/procedures/#procedure_db_schema_reltypeproperties[`db.schema.relTypeProperties()`] produces a list of strings representing the potential Java types for a given property.
+In an upcoming major release of Neo4j, this will be updated to represent the possible Cypher types for that property instead.
+For all available Cypher types, see the section on xref::values-and-types/property-structural-constructed.adoc#types-synonyms[types and their synonyms].
