 Todo list
 -----
 
-* Add in-script functions
-* New static functions
-* Loops, and if statements
+This section will obviously expand and adapt to the direction of the language. This is going to change rapidly.
 
+* Add in-script functions
+* Add script including
+* Loops, and if statements
+* More networking function flexibility
+* File pull / file push functionality
 
 Done

 * Simple syntax checking and error reporting 
 * Up to 32 layer function piping
 * Support for linux system calls

 Changelog
 -----
+
+Changes between version bumps in SlideScript. Hoping to have a lightweight top-down scripting language
+by V1.0.0 release! From there it will be molding and preserving the art.
+
 * V0.4.0
    * Added calc function for floating math equations
    * Cleaned up some more syntax handling, as well as bugs
