 3. Two more options added: `-ifp/d` and `-ifp/s`.
 
 ###`3.3.0`: <span class="light-quote">Fri Dec 18 19:03:11 UTC 2015</span>
+
+1. `-ifp/d` and `-ifp/s` options removed. Numerous options are added to achieve the same effect.
+2. `-if` option added. It can be used to manipulate how the indexes are rendered in it's field.
+3. Support for base conversion of indexes (from base 2 to 36) added.
+4. Support for Latin conversion of indexes added.
+5. Support for extended name string rules.

 3. Names can be modified by performing regex replace. It enables generating new names by deleting/appending/modifying part of the old filename. It also enables easy conversion from lowercase to uppercase and vice-versa.
 4. Lowercase-Uppercase conversion is selective i.e you can apply case conversion in part of the name at a targeted position.
 5. Names can be modified with certain predefined rules. For example, you can insert parent directory name or working directory name or index etc... in filename in arbitrary positions.
