Modules should properly create channel lists within their options again.

PHP Module

The PHP Module is no longer available. Please use a custom API and the Display Template module to replace this functionality.

Back End / AdminCP Changes
Template Processing

Removed the ability to {vb:raw var.{vb:raw subvar}} from template syntax. The accepted format is {vb:raw var.$subvar}. Any template modifications using the former will need to be updated.
Removed obsolete {vb:link} template directive. The proper directive to use is {vb:url}.

Database Updates

The user.status field is now in the usertextfield table. This change will help prevent rows in the user table exceeding MySQL's allowed row size.

Additional Issues

Updated the processing of custom CDN URLs so that CSS and SVG files work correctly again.
