AJT 2.0 is a restructured version of AJT 1.26. All code that is GPL contaminated is removed. Starting with release 2.0, AJT will be released under the LGPL 3 license. The only things that has been removed because it did not fit the new license is EPSGraphics support. The LGPL provides more freedom to use the library, which is more important.
AJT 1.26 and prior will remain available under the GPL license, but the 1.x branch will no longer be supported.
