Changes since Webmin version 2.10

Virtualmin Virtual Servers
Aliases for an existing virtual server can now be created. An alias is a server that simply forwards all web, mail and DNS requests to another server. Alias websites can be created as a virtual server that simply redirects requests or by adding additional ServerAlias directives to the target website.
Added a new Bandwidth Monitoring page for setting up regular checking of virtual server web bandwidth usage, and inputs on the server creation and editing forms to specify the amount of bandwidth each can use. When the limit is exceeded, a configurable email is sent to the domain owner and other optional addresses. The monitoring page also displays usage and limits by all servers as a bar graph.
Added a new feature - the ability to setup Logrotate to automatically truncate and compress a virtual server's log files, so that they don't consume too much disk space.
The subject lines for emails sent when a new virtual server, sub-server and mailbox are created can now be edited, and can include template variables.
Email messages send when a virtual server or mailbox is created can now be also Cc'd to additional configurable addresses.
Added the ability to use new functions in the BIND module to speed up the process of creating slave zones on a remote DNS server.
Added a new format for mailbox usernames - mailbox@domain, the same as the email address. This only works when using Sendmail as the mail server though.
The Qmail mail server is now fully supported, with all the same capabilities as Postfix and Sendmail. Only a stock install of Qmail is required by Virtualmin - vpopmail or other similar patches are not needed.
When a mailbox is created, its empty mail file or directory is automatically created, in a location determined by the configuration of the mail server in use.
A virtual server can now be created without a Unix user, as long as it only has a DNS domain or MySQL or PostgreSQL databases. For other features, the Unix user is required.
Added an additional way to proxy a virtual server to another URL - frame forwarding.
Added the ability to easily edit the forwarding destination for proxy-only or frame forwarding websites, along with the forwarding frame page title or HTML.
Moved all template-related settings into the 'Server Templates' section, including directives for Apache websites, FTP virtual servers and DNS domains. Multiple templates can now be defined, and a template can be selected when creating a virtual server.
The home directory for a virtual server can now be enabled separate from its Unix user.
On systems like FreeBSD in which the username length is limited, the prefix for mailbox usernames is now selectable when creating a server.
Added an option to automatically disable a server when it reaches its bandwidth limit.
Added an option to send an email message when a server is approaching (within some percentage) its bandwidth limit.
Added support for third-party plugin feature modules.
Added support for mailbox user plugins, which can add additional inputs and capabilities to a mail user.
Added a script to restore domains and features from the command line.
Fixed a bug when attempting to rename a PostgreSQL user on older versions that don't allow it.
Added a Module Config option for a jailed FTP shell.
