Note: "auto" identity added to help with emails ending up in spam or junk boxes because of missing headers

## 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,
  but not displayed in header -- Cc receiver only saw email To:
  line and no Cc line, but did get the email (To receiver
  saw same)

## 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
380
    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
384
    `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
