+  * utils/hbmk2/hbmk2.prg
+    ! Fixed to use hb_osPathSeparator() instead of hardcoded
+      backslash in mingw* init section, as it may also be used
+      on *nix in cross compilation scenarios.
+    ! Dropped .exe extensions from mingw* init section to also
+      work on *nix systems.
+    * Extended xmingw, mingw32ce detection for all *nix systems.
+
+  * contrib/hbodbc/odbc.c
+    ! Cast.
+
+  * INSTALL
+  * config/global.cf
+    * Removed requirement of 3.81 or upper GNU Make, now it's a
+      recommendation only. If I understand correctly after

+      older ones can also be used without parallel build feature.
+      Lowered minimum version to 3.70.

    Please evaluate these points before reporting an issue on the mailing list.
 
    - Make sure to have carefully read this document.
-   - Make sure to use a supported GNU Make version as indicated in
-     this document. Older versions are buggy and won't work.
-     Typical problem encountered with buggy GNU Make:
-        *** missing `endef', unterminated `define'.  Stop.
-        *** missing `endif'.  Stop.
    - Make sure to do a 'clean' before doing a build after refreshing
      the sources.
    - Make sure to do a fresh checkout from the sf.net source repository
