The Horde Team is pleased to announce the first alpha release of the Internet
Mail Program (IMP) version H4 (5.0).

IMP, the Internet Mail Program, is one of the most popular and widely deployed
open source webmail applications in the world. It allows universal, web-based
access to IMAP and POP3 mail servers and provides Ajax, mobile and traditional
interfaces with a rich range of features normally found only in desktop email

IMPORTANT! This is a preview version that should not be used on production
systems. This version is considered feature complete but there are  
likely to be
bugs. You should not use this preview version with existing production
data. Migration of data from earlier versions has not been fully  
tested yet and
is not supported.

We encourage widespread testing and feedback via the mailing lists or our bug
tracking system. Updated translations are very welcome, though some strings
might still change before the release candidates are prepared.

To install IMP, you need to install Horde first. See
https://github.com/horde/horde/blob/master/horde/docs/INSTALL for  
details. Once
Horde is installed, you can install IMP with the following command:

   pear install horde/imp-alpha

Then log in to Horde with your adminstrator account to configure the
application and install the database schema from the configuration interface.

The major changes compared to the IMP version H3 (4.3) are:

     * Updated for Horde 4
     * New mobile frontend
     * Much improved AJAX frontend including a vertical pane layout
     * New IMAP library written from scratch with broad RFC support and huge
       performance improvements
     * More powerful search and filter functionality
     * Smart-reply feature
     * Localized special folders
     * Better display of HTML messages
     * HTML signatures
     * Draft auto-saving
     * Support for custom IMAP flags
     * Reduced memory usage

Have fun!

The Horde Team.
