Finally, a beautiful CSS system and Ajax library, through Micro. Not only is it beautiful, but it's orders of magnitudes smaller in bandwidth usage than Bootstrap, and way easier to create custom skins on top of.
In addition, there have been fixed a severe error in the URL resolver, which means everyone should really get this latest version, since URLs with "/" within them, barely worked at all in the previous version.
Due to the latter point, I am giving away free proprietary licenses of this version, to all my customer who purchased the previous version, Zen that is.
If you want to test out the latest Micro features, make sure you download both System42 in addition to Micro - And of course, this package of Phosphorus Five.
For information about how to get started, you can see this YouTube video.
For more release notes, and screenshots of the new skins, check out my blog
Have fun :)
