+ - Added write support to address book LDAP backend. Patch by David
+ Hardeman (#1495763).
+ - Added message copy options.
+ - Removed html formating from address book backend classes. Added
+ fullname() method to addressbook_backend class. Moved
+ htmlspecialchars() sanitizing from address book backend classes to
+ html output code. If third party code displays errors from address
+ book object in html, errors must be sanitized and ASCII line feeds
+ should be converted to html line breaks.
+ - Add note to conf.pl / config_default.php to warn users that set
+ sensitive passwords in that file to properly secure it.
+ - Prevent modifications in advanced identities, when editing of
+ identities is disabled.
+ - Configuration utility does not allow 8bit symbols in IMAP folder names
+ (#1485501).
+ - Address book file backend will break with error message, if required
+ address book fields are not available. Prevents address book corruption
+ and address book format violations that can cause PHP notices.

+ - Make the base for the SquirrelMail URL configurable. Adds a new variable
+ config_base_location to config.php and a new option to conf.pl. This is
+ to prevent problems in installs where our heuristic doesn't work
+ correctly (#1521299, #1460675, #1110064, #1000850, #1113791).
+ - Removed conf.pl dependency on Perl IO::Socket module. Automatic detection
+ of supported authentication mechanisms is disabled, if IO::Socket is not
+ available.
+ - Removed HTTP Status header from signout page (#1424748).
+ - config_default.php is loaded before site configuration file.
+ config_local.php overrides are removed from config.php and loaded by
+ main initiation script.
+ - Fixed resuming of compose when session expired while writing, and make
+ sure the code only sets those variables that are needed in compose and
+ are not already set. Thanks James Bercegay from GulfTech for pointing
+ this out.
+ - Subfolders of system folders are not tagged as special in folder
+ management page in order to allow rename and delete operations with
+ subfolders (#1460011).
+ - Trash subfolders are allowed in courier. INBOX.Trash is not treated
+ as special on Courier, unless some SquirrelMail configuration option
+ marks this folder as special (#1354393). Configtest utility should
+ display warning, if Courier IMAP XMAGICTRASH extension is detected.
+ - Show purge link for Trash folder without any messages, if folder has
+ subfolders (#1413569).

+ - Added Courier IMAP OUTBOX check to configtest utility.
+ - Moved login_form hook to its own table row on login page.
+ - Added check_plugin_version() function.
+ - If mailbox name starts with slash or contains ../, error message is
+ generated. Safety check for insecure default UW IMAP setup (#1557078).

+ - Security: work around an issue in Internet Explorer that would guess
+ the mime type of a file based on contents, not Content-Type header.
+ - Security: Multiple IE cross site scripting issues related to the
+ generous parsing of the words 'expression' and 'url' by IE.
+ - Security: Removing @import when sanitizing html mail.
