**************************************
*** SquirrelMail Stable Series 1.4 ***
**************************************

Version 1.4.23 - SVN
--------------------
  - Added capability to issue SEARCH commands in literal format (so that
    non-ASCII search terms are handled RFC-correctly).
  - Fixed hook name clash: new "smtp_auth" hook added in version 1.4.22
    has been renamed to "smtp_authenticate"
  - Added SASL PLAIN mechanism for IMAP logins; backported from version
    1.5.2.
  - Prevent syslog warning in call_user_func_array() call when no
    arguments given.  Patch from Jean-Philippe Guerard (#3309935).
  - Changed the read_body_menu_top hook from concat_hook_function to
    do_hook_function (plugin authors please note)
  - Always ensure that the Reply-To header is a full email address in
    outgoing messages
  - Fixed issue with Noselect mailboxes being clickable in folder list
  - Made performance improvements in mailbox listing
  - Attachment filename extensions changed from ".msg" to ".eml"
  - Unified address book searches somewhat: file-backed address books now
    search in each field individually; database-backed address books now
    search in fields other than first/last name (nickname, email); LDAP-
    backed address books now search in common name fields as well as by
    email address (cn, sn, givenname, mail)
  - You may now enable LDAP-backed address books to be listed (using
    the "List all" button on the address search screen accessed via
    the "Addresses" button on the compose screen) by adding
    "$ldap_abook_allow_listing = TRUE;" (without quotes) to
    config/config_local.php (previously, this required editing of a
    file).
  - Added ability to control browser rendering mode (quirks versus
    standards) - see the $browser_rendering_mode setting in
    config/config.php or the "4. General Options ==> 19. Browser
    rendering mode" setting in the configuration tool (#3240356).
  - Added "search_index_before" hook (analog of the "mailbox_index_before"
    hook)
  - Made performance improvements in security token handling
  - Improvements for compatibility with PHP 5.4.
  - Added option that allows users to have replies to their own
    messages sent to the recipient of the previous message (#3520988).
  - Added Solarized Light and Solarized Dark themes, by Pavneet Arora.
  - Added associative edit list option widget, with optional folder
    list selector for values
  - Added option to use blank spacer instead of security image ("This
    image has been removed for security reasons.") for replacing
    unsafe images.
  - Full date and time is used as "title" (mouseover) text for dates
    shown on the message list screen
  - Custom Stylesheets are now sorted on the Display Preferences page
  - $xtra in the displayHtmlHeader function is now available in the
    global scope so that plugins can modify it during the generic_header
    hook
  - Added some generic client-side (JavaScript) libraries (including
    an asynchronous server request mechansim). See the new /scripts
    directory (plugin authors can refer to the plugin documentation
    for how to use them)
  - Added optional JavaScript folder list refresh ("check mail")
    mechanisms that try to avoid refreshing if server is not responding -
    see the $check_mail_mechanism setting in config/config.php or the
    "4. General Options ==> "21. Auto check mail mechanism" setting in
    the configuration tool.  (If you do not update your configuration,
    you will get messages in your logs:  "PHP Notice:  Undefined variable:
    check_mail_mechanism in /path/to/squirrelmail/src/left_main.php on
    line 322...")
  - Added advanced control over the SSL context used when connecting
    to the SMTP and IMAP servers over SSL/TLS (thanks to Emmanuel
    Dreyfus).  You can take a look at $imap_stream_options and
    $smtp_stream_options in config_local.example.php in SquirrelMail
    version 1.5.2 for more information.  These configuration settings
    should work the same under 1.4.23:
    http://sourceforge.net/p/squirrelmail/code/HEAD/tree/trunk/squirrelmail/config/config_local.example.php
  - Added ability to show login error from the IMAP server instead of
    traditional "Unknown user or password incorrect" (thanks to Alain
    Williams).  See $display_imap_login_error in the configuration
    file or "4.  General Options ==> 22. Display login error from IMAP"
    in the configuration tool.
  - Configuration tool now shows the SquirrelMail version
  - Added new attachments_top hook to src/read_body.php
  - When resuming a draft, correct (from) identity is now pre-selected
  - Removed overly-restrictive character limitations on address book
    nicknames
  - Prevent session lock-up caused by filters plugin trying to move
    messages in an account that is over quota
  - Added MD5 alternative to directory hash calculation
  - Added ability for administrator to control whether or not users
    can edit their reply-to address ($edit_reply_to in config.php)
  - Added new "login_before_page_header" (boolean) hook; allows
    plugins to have more explicit control over login page header
  - Added new "smtp_helo_override" hook; allows plugins to override
    the HELO host sent to the SMTP server when sending messages
  - Added STARTTLS support for both IMAP and SMTP connections
  - Added PDO support for database connections, so no external
    database module needs to be installed
  - compose_send hook now has $draft flag in hook arguments
  - Fixed insufficient sendmail command argument escaping (thanks
    to Mitchel Sahertian, Beyond Security/Dawid Golunski and Filippo
    Cavallarin for bringing this to our attention). [CVE-2017-7692]
  - Upgraded preferences for the delete_move_next plugin.  Automatic
    user preference updates are included, but note that if your
    installation is new, or all user prefs have been converted from
    "on"/"off" to 0/1 then you can add the following to SquirrelMail's
    config/config_local.php to avoid convertign legacy values over and over:
       $do_not_convert_delete_move_next_legacy_preferences = TRUE;
  - Added ability to control the display of the "Check Spelling"
    button provided by the squirrelspell plugin, which allows
    administrators to offer this plugin but keep it out of the way
    for users who do not want it. Put sqspell_show_button=0 in
    default preferences if it should be hidden by default
  - Added ability (and user preference) to return to message list
    after moving a message
  - Search enhancement: Added ability to search in more than one
    header without having to search the body
  - Add ability for saved drafts to indicate if they are a reply and
    if so, to which message, and mark that message as replied when
    the draft is finally sent
  - Added option to allow returning to the message one had been
    replying to after sending
  - Sanitize user-supplied attachment filenames (thanks to Florian
    Grunow for reporting this issue) [CVE-2018-8741]
  - Allow users who cannot edit their email address but who have
    multiple identities to edit all their identities
  - Changed anti-CSRF security token lifetime to be session-based.
  - Added favicon and ability for admins to use their own by setting
    $head_tag_extra in config_local.php (see documented comments in,
    for example, src/webmail.php)
  - Altered hook types "do_hook_function" and "concat_hook_function"
    such that the ultimate hook return value (in its current state,
    as computed (or not) by the plugins that have executed previously)
    is both globalized and passed as an additional argument to each
    plugin.  This allows plugins to cooperate better and not overwrite
    each other's return values.
  - Updated SVG handling, closing several related vulnerabilities
    (#2831) [CVE-2018-14950] [CVE-2018-14951] [CVE-2018-14952]
    [CVE-2018-14953] [CVE-2018-14954] [CVE-2018-14955]
  - Added IMAP ID command (RFC2971), sent after every login - use
    by setting $imap_id_command_args in config/config_local.php
    (see notes in functions/imap_general.php for more details)
  - Fixed PHP7 warnings (#2847)
  - Added handling for RCDATA and RAWTEXT elements in HTML sanitizer
    [CVE-2019-12970]
  - Added the ability to modify of the value of the global $PHP_SELF
    variable used throughout the SquirrelMail code.  The administrator
    may do so by adding the configuration settings $php_self_pattern
    and $php_self_replacement to config/config_local.php, where the
    pattern should be a full regular expression including the
    delimiters. This may be helpful when the web server sees traffic
    from a proxy so the normal $PHP_SELF does not resolve to what it
    should be for the real client.
  - Users can now mouse over the checkbox on the message list to see
    who a message is from
  - Show more accurate filesize for uploaded files and base64-encoded
    attachments (when reading a message)
  - Migrate away from create_function() as long as we have PHP 5.3+

Version 1.4.22 - 12 July 2011
-----------------------------
  - Backported default timezone fix from version 1.5.2; helps mitigate
    timezone errors in environments where a default has not been set
    by the administrator.
  - Fixed system lock-ups caused by a combination of certain rare,
    malformed message headers and buggy versions of PHP mbstring
    (#3053349).
  - Now allow multiple plugins to handle (add links for) a single
    attachment MIME type.
  - Now allow administrators to disable all plugins or enable just
    a select few plugins (overriding the active plugins in the normal
    configuration) by setting $temporary_plugins as an empty array
    (all disabled) or an array with one or more plugin directory names
    in config_local.php.
  - Backport fix for call_user_func_array not supporting NULL as empty
    array in PHP 5.3.3
  - Fixed sqauth_read_password() for plugins on the login_verified hook.
  - Added SMTP SASL PLAIN authentication option to configuration tool
    (core support for such is not new).
  - Gmail doesn't support standard search commands; removed sort buttons.
  - Forced addition of a file suffix to attachments that lack a filename
    (helps forwarded messages avoid spam filters) (thanks to Petr
    Kletecka) (#3139004).
  - Fixed missing security token in listcommands plugin.
  - Added smtp_auth hook (thanks to Emmanuel Dreyfus).
  - Made speed enhancements to threaded message display (thanks to Siim
    Poder) (#3288123).
  - Allow administrators to configure subfolders of user INBOXes to be
    treated as special folders by adding $subfolders_of_inbox_are_special
    to config_local.php.
  - Fixed incorrect display of INBOX subfolders under some configurations.
    IMPORTANT: You may need to update your configuration so that
    $default_sub_of_inbox is TRUE if it was FALSE (e.g., Courier IMAP users)
    and after updating to this version, your special folders are no longer
    listed at the top of your folder list.  Also, if this change prevents
    users from logging in with an error such as "ERROR: Could not complete
    request.  Query: CREATE "Trash" Reason Given: Invalid mailbox name.",
    you will need to correct the user preference values for the problem
    folders.  You can do so with commands such as the following for file-
    based preferences (adjust the data directory location as needed):
        find /var/lib/squirrelmail/data/ -name *.pref -exec sed --in-place 's/trash_folder=Trash/trash_folder=INBOX.Trash/g' {} \;
        find /var/lib/squirrelmail/data/ -name *.pref -exec sed --in-place 's/draft_folder=Drafts/draft_folder=INBOX.Drafts/g' {} \;
        find /var/lib/squirrelmail/data/ -name *.pref -exec sed --in-place 's/sent_folder=Sent/sent_folder=INBOX.Sent/g' {} \;
    Or, for database-based preferences:
        UPDATE userprefs SET prefval = 'INBOX.Trash' WHERE prefkey = 'trash_folder' AND prefval = 'Trash';
        UPDATE userprefs SET prefval = 'INBOX.Drafts' WHERE prefkey = 'draft_folder' AND prefval = 'Drafts';
        UPDATE userprefs SET prefval = 'INBOX.Sent' WHERE prefkey = 'sent_folder' AND prefval = 'Sent';
    MAKE SURE to back up your user preferences first!
  - Optimized message highlighting rules; faster message list display
    and faster highlight rules management (thanks to C. Bensend for
    extensive effort helping diagnose)
  - New Mail plugin no longer removes normal organization title when
    putting the number of new messages in the browser title
  - Added clickjacking protection (thanks to Asbjorn Thorsen and Geir
    Hansen for bringing this to our attention). [CVE-2010-4554]
  - Fixed XSS holes in generic options inputs, XSS hole in the SquirrelSpell
    plugin, XSS hole in the Index Order page, and added anti-CSRF protection
    to the empty trash feature and the Index Order page (thanks to Nicholas
    Carlini for finding all these issues).
    [CVE-2011-2752, CVE-2011-2753, CVE-2010-4555]
  - Fixed XSS problem with unsanitized style tags in messages. [CVE-2011-2023]

    encoding (includes #2987016 amongst several other issues reported via
    mailing list, etc.) (Many thanks to Zdenek Pytela for the untiring help
    diagnosing and testing.)

    thanks to Daniel Watts
  - Fix test for signout.php in the logged in check in is_logged_in() so it

    rely on this function guaranteeing that the user is logged in.
  - Use attachment_dir only at the point where we're actually
    reading from / writing to the files, do not carry it around
    in the object. This makes us safer in the event the object
    is somehow exposed to the outside world.

    since it was not made use of and in rare cases, made sessions too big.

  - Removed invalid $sendmail_path check in configuration utility.
  - Backported calendar plugin updates from devel branch. Fixed display of
    multiline events (#1291081) and sanitizing of quotes (#705796). Fixed

    characters. Moved html sanitizing from backend functions to display
    code. Removed direct access to $_GET and $_POST variables and
    simplified form variable processing.
  - Fixed some mailbox caching issues, when messages are deleted or moved
    not in first mailbox page. Fixed use of mailbox cache in right_main.php

    newly created mailbox.
  - Undefined variable in src/right_main.php.
  - Security: Local file inclusion in functions/plugin.php with

  - Prevent modifications in advanced identities, when editing of
    identities is disabled.
  - Fix incorrect parsing of From with nested parentheses (#1241506).
  - Tightened code in search.php for disputed security report. We don't

--------------------------------
  - Security: MagicHTML fix for comments in styles (reported

    Patch by Ray Ferguson, backported from devel.

  - Added blank.png for missing image support.
  - Fixed cid handling from Outlook Express client when it doesn't create a

    references files local to the sending machine.  This causes issues
    with Internet Explorer.

    #1013888).
  - mail_fetch plugin should check destination folder before trying to store
    messages in it. INBOX is used as fallback folder. By default plugin
    can use only subscribed mail folders that can store messages (#584658).
  - Added mbstring.func_overload!=0 workaround (#929644, #1061699).
    src/configtest.php is modified to warn about broken PHP configuration.
  - Fixed use of squirrelmail_language cookie with PHP register_globals =
