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

This is primarily a maintenance release which addresses a
smattering of small issues and adds some fine-tuning of
recent changes.  It also closes two relatively low-risk
security issues.

Before this release, for environments with highly active
users, the number of security tokens could have bloated
user session (and preference) files to an unacceptable
size, hurting overall responsiveness.  This release scales
back the default validity period of security tokens from
30 days to two days, which should fix this problem in most
cases.  The administrator is always free to change this
value by specifying $max_token_age_days in
config/config_local.php.

There are also fixes for minor issues related to header
folding, faster and more resilient display of encoded
subjects, quoting of encoded addresses upon reply, provision
of a subject when using forward-as-attachment, and a few
other tidbits.

For a complete list of changes, please see the file "ChangeLog"
in the doc/ directory.


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

This release also includes fixes for two low-risk
vulnerabilities.  The first, CVE-2010-1637, allows
authenticated users to use the Mail Fetch plugin as a
network/port/DNS scanner.  The second, CVE-2010-2813,
poses a denial-of-service risk when passwords containing
8-bit characters are used to log in.  While we
characterize these issues as fairly low risk, it is
nevertheless recommended that users of previous versions
of SquirrelMail upgrade at their earliest convenience.


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

Translations are not a part of the main SquirrelMail package.  They
are downloaded separately; you can obtain all languages in one
package or get an individual language.  You can find these packages
on our web site.  They also contain installation instructions.
