Partial Release
Although the Diesel framework is still in experimental stage and has not been publicly released yet, it has produced along the way many standalone libraries that recently began to be released under GPL License and are made available on 12939's Code project website.
By doing so, aside from wishing to be helpful to the vast community of PHP coders, our main goal is to drive some interest on the project's development and to build some sort of a community around the product.
Dixie4
Diesel is projected to be packaged and released as Free Software under distribution name Dixie4, with grindings targeted at specific audiences. It's yet early to anticipate a release date, and it can only be successful with some acknowledgment and support from the Free Software community. Meanwhile, the basic blocks of the framework will be selectively released, when judged mature enough.
