+Updates in 2.0 Release
+----------------------
+
+  1. Merged scale & operations to single flag
+     v1.0 had normalize/equalize handled by "-e" flag and rest of
+     image operations by "-s" flag. Both are merged into "-s" in
+     this release.
+
+  2. New option to clip image min/max
+     You can limit the pixel-values in output image using the flag
+     "-r". For eg: -r 10:300 to generate jpegs with pixel values in
+     the range 10 to 300.
+
+  3. New option to negate image option
+     A negative image can be generated using "-n" flag.
+
+  4. New option to resize image
+     zoom or shrink output image by "-z <zoomfact>".
+
+  5. New option to choose jpeg quality factor
+     You can choose the jpeg quality factor by "-q <quality>"
+     Quality factor was fixed at 100 in previous release.
+
+  6. New option to specify output directory for saving jpeg images
+     Output location can be specified by "-d </path/to/folder>"
+     If the target directory does not exist, the whole tree will be
+     created.
