*** SquirrelMail Devel Series 1.5 ***
*************************************

Version 1.5.2 - SVN
-------------------
  - Fixed system lock-ups caused by a combination of certain rare, malformed
    message headers and buggy versions of PHP mbstring (#3053349, $2987016).
  - Fix broken set_url_var function in functions/html.php (#1729814).
  - Fix incorrect detection of auth mechanisms in conf.pl (#1727033).
  - The search expression in the LDAP backend of the Addressbook is now
    configurable, which can allow the result set to be expanded.
  - Preliminary support for NAMESPACE in Squirrelmail IMAP Backend: NAMESPACE
    is parsed and stored in session upon login.
  - Now uses the $Forwarded IMAP keyword for forwarded messages, when it is
    enabled or when arbitrary keywords ("PERMANENT FLAGS \*") are permitted.
    RFC 4550, paragraph 2.8.
  - Added support for authorization identifier in IMAP backend, for SASL
    authentication mechanisms PLAIN and DIGEST-MD5. This can be set upon login
    by use of an external plugin.
  - Fix warning about array required in array_keys for display options when no
    fontset is defined.
  - Added "bad plugin" blacklist in configtest.php.
  - Fix MagicHTML fix with respect to parsing of u\rl in IE.
  - Added monitored folders option to newmail plugin.
  - Tweaked STARTTLS option for SMTP/IMAP to allow previous settings of just
    pure TLS not to be used to assume STARTTLS.
  - Fixed quotes in configuration strings in administrator plugin.
  - Fixed View as HTML link so it doesn't forget it was part of a seach result.
  - Don't use delimiter in IMAP subscription command, when noselect folder is
    created.
  - Security: Possible cookie theft in src/redirect.php if 
    register_globals is enabled, and malicous site is running
    in same domain.
  - Stop URL parsing, if 8bit symbols or HTML entities are detected (#1356798).
  - Added new color themes by Jeremy Landes, Tammi Maggard and Lucas Austin-Howe 
    (#1378332), (#1377567), (#1377529), (#1377528), (#1377527), (#1377526), 
    (#1377525), (#1393188).
  - Issue loading options page always loaded the prefs 
    initial_value on display, instead of the users' value.
  - Adding the message_body hook to src/view_html.php and src/view_text.php,
    allowing display of unsafe images when viewing HTML attachments and when
    HTML is in an <iframe>.
  - Fixed from address in case of MDN receipts (patch from Dimitar Pashev)
  - Advanced tree folder listing is moved to templates. $advanced_tree 
    configuration variable is removed.
  - Added system locale tests to configtest.php script.
  - Fixed invalid HTML output that caused error notices in compose.php (#1454409).
  - Introduction of centralised initialization file init.php. Location of some
    scripts is changed. If code tries to use older script layout, scripts will
    break and display error messages.
  - Added session regenrate id functionality to prohibit session hijacking.
  - Fixed sqsession_cookie function for setting HttpOnly cookie attribute.
  - Reduce references header in a smart way to avoid "header too long"
    errors from SMTP servers in really long threads (#1167754, #1465342).
  - Added code that allows to use internal password functions in sqimap_login().
    Switched plugins to use this code instead of accessing key and otp information
    directly.
  - Fixed automatic mailbox creation in left_main.php. 1.5.1 mailbox caching 
    broke detection of unsubscribed special folders (#1461578).
  - Undo extra sanitizing in decodeHeader() function (#1460638).
  - Added workaround for broken OpenBSD 3.8+ setlocale() function (#1427512).

  - Added configtest hook in src/configtest.php.
  - Improved error handling for the help pages.
  - Fixed possibility to use single quote in provider name (#1475744).

    (#1031455).
  - Added error handling and $onlylocal argument to abook_init hook.
  - Added PHP 5.1.0 date_default_timezone_set() function support. Allows
    to use time zone settings in PHP safe_mode.
  - Sanitized IMAP folder names in error_message() function and filters plugin.
  - Take X-Forwarded-Host HTTP header in consideration when constructing
    base_uri for redirects; reduces problems with transparent proxies
    (#1488590).
  - Fixed server capability retrieval for "double" cases in capability
    response, like "FOO FOO=bar".
  - Various address book database backend modifications. Fixed invalid
    error checks in insert() and delete() methods (checks caused PHP 
    warnings). Turned on Pear DB field case portability mode. Escaped SQL
    wildcards in search() method. Handle nickname changes in modify()
    method when new nickname is already in use. Made search expressions
    case insensitive in search() method.
  - Added special folder (Drafts, Sent, Trash) translations in mailbox 
    tree and folder selection boxes.
  - 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.
  - Added line length setting in local_file address book backend (#1181561).
  - Removed proprietary wrap attribute from compose form (#1512681).
  - Fix URL for Read Receipts being incorrect in some cases (#1177518).
  - Don't allow selecting INBOX as Sent, Draft or Trash folder (#1242346).
  - Session cookies are turned on, if session.use_cookies is turned off
    in PHP configuration (#1518885).
  - Make the default attachment dir /var/local/squirrelmail/attach, not
    $data_dir.
  - Add HTML labels for form elements.
  - Fixed spamcop web based reporting form (#1519673) and removed service
    type options from spamcop plugin.
  - Removed trailing ?> from function scripts.
  - Added checks for non-existent backend to AddressBook class.
  - 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).
  - Custom SMTP AUTH configuration variables are moved from config_local.php
    to main configuration file.

  - If mailbox name starts with slash or contains ../, error message is
    generated. Safety check for insecure default UW IMAP setup (#1557078).

    (optionally for one named user, otherwise for all users).
  - Security: close cross site scripting vulnerability in draft, compose
    and mailto functionality [CVE-2006-6142].
  - 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.
  - Redesigned plugin hook system.  do_hook_function() has been removed

    in PHP 4.4.5 (#1664155).
  - If a date-header cannot be parsed, display the unparsed version as a
    better-than-nothing alternative.
  - Fix Priority and Receipt compose options being reset after return from
    HTML addressbook, and allow returning from an empty address book (#1673056).

  - Add dynamic textarea sizing slider control to compose screen (default_advanced 
    skin)
  - Security: fixes for the HTML filter to counter further XSS exploits:
    HTML attachments containing 'data:' URLs, Internet Explorer-specifc

    cannot be circumvented by manipulating the URL. External plugins might
    rely on init.php guaranteeing that the user is logged in.
  - Sort readdir() output in conf.pl (#1755886).
  - Made the webmail_top hook work again for plugins that want to change
    the URI of the "right" frame; plugins have to change the value of the

    "not defined" error on session timeouts.
  - Allow custom session handlers to work correctly (and be defined at the
    application level with SquirrelMail).
  - Fix off-by-one in bodystructure parsing triggered by servers sending
    a body location part (e.g. Sun Java System Messaging Server). Thanks
    John Callahan (#1808382).
  - Invalid initialization of To: header (#1772893).
