-  
-Version 5.0.1 (April 05, 2009)
-  * Temporary fix for missing attachments
-  
-Version 5.0.0 (April 02, 2009)
-  
-  * With the release of this version, we are initiating a new version numbering
-    system to differentiate from the PHP4 version of PHPMailer.
-  * Most notable in this release is fully object oriented code.
-  class.smtp.php:
-  * Refactored class.smtp.php to support new exception handling
-    code size reduced from 29.2 Kb to 25.6 Kb
-  * Removed unnecessary functions from class.smtp.php:
-    public function Expand($name) {
-    public function Help($keyword="") {
-    public function Noop() {
-    public function Send($from) {
-    public function SendOrMail($from) {
-    public function Verify($name) {
-  class.phpmailer.php:
-  * Refactored class.phpmailer.php with new exception handling
-  * Changed processing functionality of Sendmail and Qmail so they cannot be
-    inadvertently used
-  * removed getFile() function, just became a simple wrapper for
-    file_get_contents()
-  * added check for PHP version (will gracefully exit if not at least PHP 5.0)
-  class.phpmailer.php enhancements
-  * enhanced code to check if an attachment source is the same as an embedded or
-    inline graphic source to eliminate duplicate attachments
-  New /test_script
-  * We have written a test script you can use to test the script as part of your
-    installation. Once you press submit, the test script will send a multi-mime
-    email with either the message you type in or an HTML email with an inline
-    graphic. Two attachments are included in the email (one of the attachments
-    is also the inline graphic so you can see that only one copy of the graphic
-    is sent in the email). The test script will also display the functional
-    script that you can copy/paste to your editor to duplicate the functionality.
-  New examples
-  * All new examples in both basic and advanced modes. Advanced examples show
-    Exception handling.
-  PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
-  * all new documentation
-  
-  Please note: the website has been updated to reflect the changes in PHPMailer
-Version 5.0.0. http://phpmailer.codeworxtech.com/
-  
-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("[email protected],[email protected],[email protected]");
-  
-  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
-  * dramatically simplified using inline graphics ... it's fully automated and requires no user input
-  * added automatic document type detection for attachments and pictures
-  * added MsgHTML() function to replace Body tag for HTML emails
-  * fixed the SendMail security issues (input validation vulnerability)
-  * enhanced the AddAddresses functionality so that the "Name" portion is used in the email address
-  * removed the need to use the AltBody method (set from the HTML, or default text used)
-  * set the PHP Mail() function as the default (still support SendMail, SMTP Mail)
-  * removed the need to set the IsHTML property (set automatically)
-  * added Estonian language file by Indrek P&auml;ri
-  * added header injection patch
-  * added "set" method to permit users to create their own pseudo-properties like 'X-Headers', etc.
-    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();
-  * PHPMailer has been tested with PHP4 (4.4.7) and PHP5 (5.2.7)
-  * Works with PHP installed as a module or as CGI-PHP
-    - NOTE: will NOT work with PHP5 in E_STRICT error mode

+## Version 5.0.2 (May 24, 2009)
+* Fix for missing attachments when inline graphics are present
+* Fix for missing Cc in header when using SMTP (mail was sent,

+
+## Version 5.0.1 (April 05, 2009)
+* Temporary fix for missing attachments
+
+## Version 5.0.0 (April 02, 2009)
+With the release of this version, we are initiating a new version numbering
+system to differentiate from the PHP4 version of PHPMailer.
+Most notable in this release is fully object oriented code.
+
+### class.smtp.php:
+* Refactored class.smtp.php to support new exception handling
+* code size reduced from 29.2 Kb to 25.6 Kb
+* Removed unnecessary functions from class.smtp.php:
+  - public function Expand($name) {
+  - public function Help($keyword="") {
+  - public function Noop() {
+  - public function Send($from) {
+  - public function SendOrMail($from) {
+  - public function Verify($name) {
+
+###  class.phpmailer.php:
+* Refactored class.phpmailer.php with new exception handling
+* Changed processing functionality of Sendmail and Qmail so they cannot be
+  inadvertently used
+* removed getFile() function, just became a simple wrapper for
+  file_get_contents()
+* added check for PHP version (will gracefully exit if not at least PHP 5.0)
+* enhanced code to check if an attachment source is the same as an embedded or
+  inline graphic source to eliminate duplicate attachments
+
+### New /test_script
+We have written a test script you can use to test the script as part of your
+installation. Once you press submit, the test script will send a multi-mime
+email with either the message you type in or an HTML email with an inline
+graphic. Two attachments are included in the email (one of the attachments
+is also the inline graphic so you can see that only one copy of the graphic
+is sent in the email). The test script will also display the functional
+script that you can copy/paste to your editor to duplicate the functionality.
+
+### New examples
+All new examples in both basic and advanced modes. Advanced examples show
+   Exception handling.
+
+### PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
+All new documentation
+
+## 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 = Etc/UTC (or your own zone)
+    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('Etc/UTC');`
+  - 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**
