 Change Log
 ==========
 
-### 1.6.0 - 2021-10-08
+### 2.0.0 - 2021-10-08
 
 ##### Changes
+* Updated PostgreSQL database schema to use 64-bit `bigint` as data type instead of 32-bit `integer` for all
+  primary key and foreign key columns. Hence, this release can only be used with version 4.2.x of the 3DCityDB.
+  It is not compatible with previous versions of the 3DCityDB anymore.
 * Updated impexp-client-gui to 5.0.0
 * Updated iur-ade-citygml4j to 1.4.2.
