ISPConfig 3.1.2 Released

What’s new in ISPConfig 3.1.2

This release contains a security fix and several bug fixes.

SSH user certificates were not created securely in ISPConfig versions < 3.1.2. The code to create the SSH private and public key has been completely rewritten and placed into a central function for easier maintenance in ISPConfig 3.1.2 to solve this problem. Thank you very much to Greg for reporting this issue.
