Roundcube Webmail 1.4-beta

This is a beta release of the next major version 1.4 of Roundcube webmail.
With this milestone we introduce some new features:

• New responsive skin with mobile support
• Email Resent (Bounce) feature
• Improved Mailvelope integration
• Support for Redis cache
• Support for SMTPUTF8

Because the new responsive skin is not yet fully completed, it's not enabled
by default. In order to make it the default for your users, change your
config.inc.php accordingly:

$config['skin'] = 'elastic';

Although it still needs some polishing, the new skin solves the urgent need
to enable access to Roundcube for mobile devices. The plugin elastic4mobile
makes it the default for mobile devices while keeping the configured default
for desktop browsers.

The Elastic skin is built with LESS and of course the sources are included.
They allow a certain degree of customization by adjusting some color variables.
All you need is to compile your very own customized skin with lessc.

In case you're running Roundcube directly from source or if you're not using
the complete package, you need to install 3rd party javascript modules
by executing the following install script:

$ bin/install-jsdeps.sh

This is a beta release and we recommend to test it on a separate environment.
And don't forget to backup your data before installing it.
