Actually it has been released last Thursday so this is old news. The release really is a pure bugfix release with two exceptions:

  1. We've changed our license to the 2.0 version of the Apache License

    In the Ant announcement on Cafe au Lait Elliotte Rusty Harold says

    It is also published under the new Apache 2.0 license, which may or may not be GPL compatible. (The Apache Software Foundation is telling me one thing, and the Free Software Foundation is telling me the opposite. We'll just have to wait and see how this plays out.)
    AFAIU the Apache Software Foundation says that you can take code licensed under the Apache License and redistribute it under the GPL. So from the ASF point of view it is compatible.

  2. We've added some initial support for Java 1.5. At least you can now use source="1.5" on to compile generics and all that.
