Typemock Isolator 5.0 has been released and there are a lot of cool things that come with it. The two big ones:

• Arrange/Act/Assert syntax: A more fluent syntax style for setting up your mocks. You can still use the old API, but the new one offers a nice alternative to the classic record/playback metaphor.
• Open Source licensing: I blogged about this before, but it’s finally in effect. You can get the goodness of Isolator for use in your open source project. I’ll totally be hooking this up in CR_Documentor.

This is huge. I’m totally excited. Check it out.
