Zenario 7.4.2

This update for the 7.4 branch of Zenario fixes a bug with SMTP emails, and patches a non-critical vulnerability with an unprotected minification-script:

• User forms can now have different actions for anonymous visitors and logged in extranet users.
• The Installation Information section in the About box now only appears for administrators with developer tools enabled.
• Fixed a bug where the SMTP Mail Server site setting for emails was not working.
• Fixed a vulnerability where our CSS and JavaScript minification-script could be triggered by a visitor using their browser, wasting CPU time on the server. After this update, the script can only be run from the command line, as was originally intended.
