[announce] IMP H3 (4.2-ALPHA)

[Jan Schneider]

The Horde Team is pleased to announce the first alpha release of the IMP
Webmail Client version H3 (4.2).

IMP, the Internet Messaging Program, is one of the most popular webmail
applications available.  It allows universal, web-based access to IMAP and
POP3 mail servers and provides a full range of features normally found only in
desktop email clients.

This is a preview version that should not be used on production systems. This
version is considered feature complete but a few bugs may still exist in the
code.

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 final release.

IMP version H3 (4.2) is a major upgrade in the 4.x release series, including
these enhancements:
    * Message and mailbox caching on the server side, resulting in much
      increased performance and much less web server and IMAP server load.
    * Rewrite of much of IMP's core libraries, resulting in more efficient
      memory usage, more efficient IMAP queries, smaller session sizes, and
      increased performance.
    * WCAG 1.0 Priority 2/Section 508 accessibility guidelines compliance.
    * Javascript auto-complete contact list searching.
    * Can now have multiple browser windows open without destroying the
      open session.
    * Logging of sent messages.
    * Server configuration to limit maximum number of recipients per message
      and maximum number of sent messages over a certain period of time.
    * Improved templating of output code to ease local customization.
    * Additional maintenance tasks to clean old messages from mailboxes.
    * Sorting is now saved per mailbox rather than across all mailboxes.
    * On IE and Firefox, warn users before closing popup compose window.
    * Add support for symmetric PGP encryption.
    * Preference added to dictate default cursor location in compose textarea.
    * Preference added to only verify PGP & S/MIME signed messages on
      user request.
    * Forward messages as RFC 822 parts by default; provide more options for
      forwarding messages; and be smarter about what part to use as body
      text depending on current editor (text vs. html).
    * Javascript code now uses the prototype js library, resulting in more
      robust code and more available functionality - for example, non-modal
      newmail popups.
    * Add server configuration to limit the maximum size of MIME message
      data that can be displayed inline.
    * Use tidy extension (if available) to clean up display of HTML messages
      and clean up HTML composed messages.
    * Add RSS/Atom feed for mailboxes.
    * More/improved display options for the folder lists and better handling
      of non-private namespaces.
    * Improvements/cleanups to the imap quota drivers.
    * Add additional hooks after certain actions (i.e. post-login,
      post-compose).
    * Add support for sending e-mails with Internationalized Domain Names
      (IDN).
    * Fetch public PGP keys from keyserver if not available in address book.
    * Add configuration for folders that may not be modified.
    * and much, much, much more.

Note that several of these new features require Horde 3.2+.
