 285  * Fix for missing attachments when inline graphics are present
 286  * Fix for missing Cc in header when using SMTP (mail was sent,

 290  
 291  ## Version 5.0.1 (April 05, 2009)
 292  * Temporary fix for missing attachments
 293  
 294  ## Version 5.0.0 (April 02, 2009)
 295  With the release of this version, we are initiating a new version numbering
 296  system to differentiate from the PHP4 version of PHPMailer.
 297  Most notable in this release is fully object oriented code.
 298  
 299  ### class.smtp.php:
 300  * Refactored class.smtp.php to support new exception handling
 301  * code size reduced from 29.2 Kb to 25.6 Kb
 302  * Removed unnecessary functions from class.smtp.php:
 303    - public function Expand($name) {
 304    - public function Help($keyword="") {
 305    - public function Noop() {
 306    - public function Send($from) {
 307    - public function SendOrMail($from) {
 308    - public function Verify($name) {
 309  
 310  ###  class.phpmailer.php:
 311  * Refactored class.phpmailer.php with new exception handling
 312  * Changed processing functionality of Sendmail and Qmail so they cannot be
 313    inadvertently used
 314  * removed getFile() function, just became a simple wrapper for
 315    file_get_contents()
 316  * added check for PHP version (will gracefully exit if not at least PHP 5.0)
 317  * enhanced code to check if an attachment source is the same as an embedded or
 318    inline graphic source to eliminate duplicate attachments
 319  
 320  ### New /test_script
 321  We have written a test script you can use to test the script as part of your
 322  installation. Once you press submit, the test script will send a multi-mime
 323  email with either the message you type in or an HTML email with an inline
 324  graphic. Two attachments are included in the email (one of the attachments
 325  is also the inline graphic so you can see that only one copy of the graphic
 326  is sent in the email). The test script will also display the functional
 327  script that you can copy/paste to your editor to duplicate the functionality.
 328  
 329  ### New examples
 330  All new examples in both basic and advanced modes. Advanced examples show
 331     Exception handling.
 332  
 333  ### PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
 334  All new documentation
 335  
 336  ## Version 2.3 (November 06, 2008)
 337  * added Arabic language (many thanks to Bahjat Al Mostafa)
 338  * removed English language from language files and made it a default within
 339    class.phpmailer.php - if no language is found, it will default to use
 340    the english language translation
 341  * fixed public/private declarations
 342  * corrected line 1728, $basedir to $directory
 343  * added $sign_cert_file to avoid improper duplicate use of $sign_key_file
 344  * corrected $this->Hello on line 612 to $this->Helo
 345  * changed default of $LE to "\r\n" to comply with RFC 2822. Can be set by the user
 346    if default is not acceptable

 349  * fixed phpunit.php for compliance with PHP5

 352    the http://phpmailer.codeworxtech.com website.
 353  
 354  ## Version 2.2.1 () July 19 2008
 355  * fixed line 1092 in class.smtp.php (my apologies, error on my part)
 356  
 357  ## Version 2.2 () July 15 2008
 358  * Fixed redirect issue (display of UTF-8 in thank you redirect)
 359  * fixed error in getResponse function declaration (class.pop3.php)
 360  * PHPMailer now PHP6 compliant
 361  * fixed line 1092 in class.smtp.php (endless loop from missing = sign)
 362  
 363  ## Version 2.1 (Wed, June 04 2008)
 364  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.
 365  
 366  * added S/MIME functionality (ability to digitally sign emails)
 367    BIG THANKS TO "sergiocambra" for posting this patch back in November 2007.
 368    The "Signed Emails" functionality adds the Sign method to pass the private key
 369    filename and the password to read it, and then email will be sent with
 370    content-type multipart/signed and with the digital signature attached.
 371  * fully compatible with E_STRICT error level
 372    - Please note:
 373      In about half the test environments this development version was subjected
 374      to, an error was thrown for the date() functions used (line 1565 and 1569).
 375      This is NOT a PHPMailer error, it is the result of an incorrectly configured
 376      PHP5 installation. The fix is to modify your 'php.ini' file and include the
 377      date.timezone = Etc/UTC (or your own zone)
 378      directive, to your own server timezone
 379    - If you do get this error, and are unable to access your php.ini file:
 380      In your PHP script, add
 381      `date_default_timezone_set('Etc/UTC');`
 382    - do not try to use
 383      `$myVar = date_default_timezone_get();`
 384      as a test, it will throw an error.
 385  * added ability to define path (mainly for embedded images)
 386    function `MsgHTML($message,$basedir='')` ... where:
 387    `$basedir` is the fully qualified path
 388  * fixed `MsgHTML()` function:
 389    - Embedded Images where images are specified by `<protocol>://` will not be altered or embedded
 390  * fixed the return value of SMTP exit code ( pclose )
 391  * addressed issue of multibyte characters in subject line and truncating
 392  * added ability to have user specified Message ID
 393    (default is still that PHPMailer create a unique Message ID)
 394  * corrected unidentified message type to 'application/octet-stream'
 395  * fixed chunk_split() multibyte issue (thanks to Colin Brown, et al).
 396  * added check for added attachments
 397  * enhanced conversion of HTML to text in MsgHTML (thanks to "brunny")
 398  
 399  ## Version 2.1.0beta2 (Sun, Dec 02 2007)
