As the color order of the sf2dlib changed, you have to change it in your code, or use the color.hex() function.
To fix the problems, just change "0xRRGGBBAA" to "0xAABBGGRR".
Also, the shader compiler changed to Picasso, so you'll need it in order to compile.

Libs additions: font.load, font:unload, font:getWidth, fs.getDirectory, fs.setDirectory, fs.exists
Editor additions: syntaxic coloring and mono font
sf2dlib update: you will need the latest version of ctrulib.
Also, because of the lib font needs, the sftdlib was modified.
