• Fixed bug with EndIf not working on for loops.
• Binary prefix is now pi instead of "b".
• Fixed a bug that caused crashing when no programs were in the compile list.
• Fixed a bug when nesting commands that used files.
• Fixed the Next() command in MemKit.
• The CompileOP1 entrypoint will not overwrite the appvar settings.

I know this is A LOT to take in, so I included a file "Changes.pdf" inside the download to better explain the changes.  I highly recommend reading it before you start playing around with it so you can use the new features to their full potential.

Caution: Use this version at your own risk.  It may require ROM clears and loss of data.
