title: Are code freezes still relevant when using a continuous integration build setup?
body: <p>I've used a Continuous Integration server in the past with great success, and hadn't had the need to ever perform a code freeze on the source control system. </p>
  
  <p>However, lately it seems that everywhere I look, most shops are using the concept of code freezes when preparing for a release, or even a new test version of their product. This idea runs even in my current project.</p>
  
  <p>When you check-in early and often, and use unit tests, integration tests, acceptance tests, etc., are code freezes still needed?</p>
