ChangeLog

NOTE: THIS VERSION OF PHPMAILER IS DESIGNED FOR PHP5/PHP6. IT WILL NOT WORK WITH PHP4.

Version 2.3 (November 06, 2008)

* added Arabic language (many thanks to Bahjat Al Mostafa)
* removed English language from language files and made it a default within
  class.phpmailer.php - if no language is found, it will default to use
  the english language translation
* fixed public/private declarations
* corrected line 1728, $basedir to $directory
* added $sign_cert_file to avoid improper duplicate use of $sign_key_file
* corrected $this->Hello on line 612 to $this->Helo
* changed default of $LE to "\r\n" to comply with RFC 2822. Can be set by the user
  if default is not acceptable
* removed trim() from return results in EncodeQP
* /test and three files it contained are removed from version 2.3
* fixed phpunit.php for compliance with PHP5
* changed $this->AltBody = $textMsg; to $this->AltBody = html_entity_decode($textMsg);
* We have removed the /phpdoc from the downloads. All documentation is now on
  the http://phpmailer.codeworxtech.com website.

Version 2.2.1 () July 19 2008

* fixed line 1092 in class.smtp.php (my apologies, error on my part)

Version 2.2 () July 15 2008

* Fixed redirect issue (display of UTF-8 in thank you redirect)
* fixed error in getResponse function declaration (class.pop3.php)
* PHPMailer now PHP6 compliant
* fixed line 1092 in class.smtp.php (endless loop from missing = sign)

Version 2.1 (Wed, June 04 2008)

** NOTE: WE HAVE A NEW LANGUAGE VARIABLE FOR DIGITALLY SIGNED S/MIME EMAILS.
   IF YOU CAN HELP WITH LANGUAGES OTHER THAN ENGLISH AND SPANISH, IT WOULD BE
   APPRECIATED.

* added S/MIME functionality (ability to digitally sign emails)
  BIG THANKS TO "sergiocambra" for posting this patch back in November 2007.
  The "Signed Emails" functionality adds the Sign method to pass the private key
  filename and the password to read it, and then email will be sent with
  content-type multipart/signed and with the digital signature attached.
* fully compatible with E_STRICT error level
  - Please note:
    In about half the test environments this development version was subjected
    to, an error was thrown for the date() functions used (line 1565 and 1569).
    This is NOT a PHPMailer error, it is the result of an incorrectly configured
    PHP5 installation. The fix is to modify your 'php.ini' file and include the
    date.timezone = America/New York
    directive, to your own server timezone
  - If you do get this error, and are unable to access your php.ini file:
    In your PHP script, add
    date_default_timezone_set('America/Toronto');
    - do not try to use
    $myVar = date_default_timezone_get();
    as a test, it will throw an error.
* added ability to define path (mainly for embedded images)
  function MsgHTML($message,$basedir='') ... where:
  $basedir is the fully qualified path
* fixed MsgHTML() function:
  - Embedded Images where images are specified by <protocol>:// will not be altered or embedded
* fixed the return value of SMTP exit code ( pclose )
* addressed issue of multibyte characters in subject line and truncating
* added ability to have user specified Message ID
  (default is still that PHPMailer create a unique Message ID)
* corrected unidentified message type to 'application/octet-stream'
* fixed chunk_split() multibyte issue (thanks to Colin Brown, et al).
* added check for added attachments
* enhanced conversion of HTML to text in MsgHTML (thanks to "brunny")

Version 2.1.0beta2 (Sun, Dec 02 2007)
* implemented updated EncodeQP (thanks to coolbru, aka Marcus Bointon)
* finished all testing, all known bugs corrected, enhancements tested
- note: will NOT work with PHP4.

please note, this is BETA software
** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
INTENDED STRICTLY FOR TESTING

Version 2.1.0beta1
please note, this is BETA software
** DO NOT USE THIS IN PRODUCTION OR LIVE PROJECTS
INTENDED STRICTLY FOR TESTING

Version 2.0.0 rc2 (Fri, Nov 16 2007), interim release
* implements new property to control VERP in class.smtp.php
  example (requires instantiating class.smtp.php):
  $mail->do_verp = true;
* POP-before-SMTP functionality included, thanks to Richard Davey
  (see class.pop3.php & pop3_before_smtp_test.php for examples)
* included example showing how to use PHPMailer with GMAIL
* fixed the missing Cc in SendMail() and Mail()

******************
A note on sending bulk emails:

If the email you are sending is not personalized, consider using the
"undisclosed-recipient:;" strategy. That is, put all of your recipients
in the Bcc field and set the To field to "undisclosed-recipients:;".
It's a lot faster (only one send) and saves quite a bit on resources.
Contrary to some opinions, this will not get you listed in spam engines -
it's a legitimate way for you to send emails.

A partial example for use with PHPMailer:

$mail->AddAddress("undisclosed-recipients:;");
$mail->AddBCC("email1@anydomain.com,email2@anyotherdomain.com,email3@anyalternatedomain.com");

Many email service providers restrict the number of emails that can be sent
in any given time period. Often that is between 50 - 60 emails maximum
per hour or per send session.

If that's the case, then break up your Bcc lists into chunks that are one
less than your limit, and put a pause in your script.
*******************

Version 2.0.0 rc1 (Thu, Nov 08 2007), interim release

* added MsgHTML() function to replace Body tag for HTML emails

* removed the need to set the IsHTML property (set automatically)
* added Estonian language file by Indrek P&auml;ri
* added header injection patch

  example of use:
  $mail->set('X-Priority', '3');
  $mail->set('X-MSMail-Priority', 'Normal');
* fixed warning message in SMTP get_lines method
* added TLS/SSL SMTP support
  example of use:
  $mail = new PHPMailer();
  $mail->Mailer = "smtp";
  $mail->Host = "smtp.example.com";
  $mail->SMTPSecure   = "tls"; // option
  //$mail->SMTPSecure   = "ssl";  // option
  ...
  $mail->Send();
