+  * contrib/hbct/getsecrt.prg
+    * use hb_keyCode() instead of Asc() to form numeric key value.
+
+  * contrib/hbtip/encqp.prg
+    ! Quoted-printable encoding/decoding fixed to use FOR/NEXT
+      loop instead of FOR/EACH and HB_B*() string functions to 
+      operate on binary data regardless of HVM CP.
+    ! Fixed old typo causing no encoding for line-ending whitespaces.
