 3. CHANGE LOG & FEATURES ADDED
 ------------------------------

+* Igzip compression enhancements.

+    resetting can greatly accelerate the performance of compressing many small
+    files with a dictionary.
+  - New static level 0 header decode tables. Accelerates decompressing small
+    files that are level 0 compressed by skipping the known header parsing.

+    files into one output stream.
