All about this release
======================

This version, 1.4.10a is a maintenance release, addressing
the following problems since 1.4.9a:
- Some security fixes (see below)
- Small enhancements
- A collection of bugfixes and stability enhancements
(see ChangeLog for a full list)

Version 1.4.10a was released shortly after 1.4.10 which
had a regression in compose with just one identity defined.


Locales / Translations / Charsets
=================================

Since the release of 1.4.4, the the translations for SquirrelMail are
no longer part of the main package but have to be downloaded separately;
either in one large file or an individual language. You can find these
packages through our homepage. They also contain instructions on how
to install.

That release also introduced a backport of the new Character set
decoding functions from the development branch, vastly increasing the
number of supported character sets and decoding performance.


Security issues
===============

This release addresses security issues found since the release of 1.4.9a:

There's an ongoing battle to further secure the HTML filter against malicious
HTML mail and the browsers that accept almost any malformed piece of HTML.

This release contains fixes for the following:
- HTML attachments containing "data:" URLs;
- Internet Explorer in various versions accepts many permutations of HTML
  and JavaScript in many charsets. We now properly canonicalize the incoming
  HTML to us-ascii before applying further filters. IE only.
- Request forgery through images. It was possible to include "images" in
  HTML mails which were in fact GET requests for the compose.php page sending
  mail. These images are now properly detected, and the compose form will only
  send mail through a POST request.

Thanks to Mikhail Markin, Tomas Kuliavas and Michael Jordon for reporting
(parts of) these issues and working with us to get them resolved.

These are known as CVE-2007-1262 and CVE-2007-2589.


Major updates in 1.4
====================

The 1.4.x series (as a result of 1.3 developent series) brings:

* A complete rewrite of the way we send mail (Deliver-class),
  and of the way we parse mail (MIME-bodystructure parsing).
  This makes SquirrelMail more reliable and more efficient
  at the same time!
* Support for IMAP UID which makes SquirrelMail more reliable.
* Optimizations to code and the number of IMAP calls; SquirrelMail
  is now a very scalable webmail solution.
* Support for a wider range of authentication mechanisms.
* Lots of bugfixes, some new features and a couple of UI-tweaks.


A note on plugins
=================

There have been major plugin architecture improvements since 1.2.x. Lots
of plugins have not yet been adapted to this. Plugins which are
distributed with this release (eg. in the same .tar.gz file) should work.
Plugin authors will need some time to adapt their plugins, so quite a few
plugins that did work with 1.2.x might not work with 1.4.x.

So if you have ANY problem at all, first try turning off all plugins.
If one plugin seems to be the culprit, contact the author to see if
a 1.4.x version is underway.

Plugins that worked with previous 1.4.x versions should continue to work
without changes with this version.


Reporting my favorite SquirrelMail 1.4 bug
==========================================

We constantly aim to make SquirrelMail even better. So we need you to
submit any bug you come across! Also, please mention that the bug is
in this 1.4.9a release, and list your IMAP server and webserver details.

Thanks for your cooperation with this. That helps us to make
sure nothing slips through the cracks. Also, it would help if
people would check existing tracker items for a bug before reporting
it again. This would help to eliminate duplicate reports, and
increase the time we can spend CODING by DECREASING the time we
spend sorting through bug reports. And remember, check not only OPEN
bug reports, but also closed ones as a bug that you report MAY have
been fixed in our source code repository already.
