Dear E-Mail User

Due to the package compromise of 1.4.11,1.4.12 and 1.4.13, we are forced to release 1.4.15 to ensure no confusions. While initial review didn't uncover a need for concern, several proof of concepts show that the package alterations introduce a high risk security issue, allowing remote inclusion of files. These changes would allow a remote user the ability to execute exploit code on a victim machine, without any user interaction on the victim's server. This could grant the attacker the ability to deploy further code on the victim's server.

We STRONGLY advise all users of 1.4.11, 1.4.12 and 1.4.13 upgrade immediately.
