 # Eobard
 
-This task can be done in much less lines and much less visual complexity by using the "StringBuilder" class, but I wanted to build it on my own to practice writing Java, so the only thing I allowed myself to use is basic programmatic operations.
+An Java desktop application for reversing any text quickly and elegantly. Built with elementaryOS.
 
 Changelog:
 
-- Version 2.0 - The much unexpected release! Eobard is now completely refactored and documented. This version eliminates the need for the "ArrayList" library, and now the only non-default library used is JOptionPane. I also fixed the readme a bit. 
+- Version 3.0:
+	- Changed GUI to use "text" terminology rather than "string".
+	- Completely refactored input validation to check for input comprised entirely of whitespace.
+	- Added more documentation
+	- Fancified input dialog boxes
+	- Branded as actual application instead of practice code
+	- Added TODO section
+	- Added new screenshots
