Grigori has announced that Enterprise Library 4.0 has shipped.
You can get EntLib 4 here. I have been watching this team work hard for the last few months, had a number of conversations with Chris about it, looked at a few problems (note: I did not say I helped solve these problems, I just looked, asked stupid questions, and that allowed Chris to figure them out). This should be a solid release with some great features, bug fixes, and performance improvements.
Unity 1.1 has also shipped. EntLib 4.0 is built on top of Unity, and takes advantage of it. I have said it before, Unity Rocks!
Now, I need to upgrade to Unity 1.1 for my articles on re-writing the Composite Web Application Block to use Unity.
