+
+**7.4**
+* ILE RPG runtime: SI71537
+* ILE RPG compiler: SI71536
+* SQL Precompile support UTF-8 stream files: SI70942
+
+**7.3**
+* ILE RPG runtime: SI71535
+* ILE RPG compiler: SI71534
+* SQL Precompile support UTF-8 stream files: SI70936
+
+If the PTFs have not been installed, the library must be recompiled to disable the latest features, such as `assertEqual()`. PTFs SI70942 and SI70936 are required for compiling test suites from UTF-8 (CCSID: 1208) source stream files.
