SquirrelMail 1.4.20 Release Candidate 2 Now Available

Hot on the coattails of 1.4.20 release candidate 1, we received some helpful feedback from our friends at Secunia Research and have followed up with another release candidate. The risk of using the 1.4.20 release candidate 1 package instead of this one is very low, but we encourage the community to help test code that we hope to release as officially stable in the near future. Those who can upgrade to release candidate 2 are encouraged to do so!
