* Fix to only perform the charset conversion if a 'from' and a 'to' charset are given (make no assumptions about what the charset was) #1276 [Jamis Buck]
* Fix attachments and content-type problems #1276 [Jamis Buck]
* Fixed the TMail#body method to look at the content-transfer-encoding header and unquote the body according to the rules it specifies #1265 [Jamis Buck]
* Added unquoting even if the iconv lib can't be loaded--in that case, only the charset conversion is skipped #1265 [Jamis Buck]
* Fixed that email address like "Jamis Buck, M.D." <wild.medicine@example.net> would cause the quoter to generate emails resulting in "bad address" errors from the mail server #1220 [Jamis Buck]
* Fixed that if charset was found that the end of a mime part declaration TMail would throw an error #919 [lon@speedymac.com]
* Fixed that TMail::Unquoter would fail to recognize quoting method if it was in lowercase #919 [lon@speedymac.com]
* Fixed that TMail::Encoder would fail when it attempts to parse e-mail addresses which are encoded using something other than the messages encoding method #919 [lon@speedymac.com]
* Consolidated the server configuration options into Base#server_settings= and expanded that with controls for authentication and more [Marten]
NOTE: This is an API change that could potentially break your application if you used the old application form. Please do change!
* Added Base#deliveries as an accessor for an array of emails sent out through that ActionMailer class when using the :test delivery option. [bitsweat]
* Added Base#perform_deliveries= which can be set to false to turn off the actual delivery of the email through smtp or sendmail.
This is especially useful for functional testing that shouldn't send off real emails, but still trigger delivery_* methods.
* Added option to specify delivery method with Base#delivery_method=. Default is :smtp and :sendmail is currently the only other option.
Sendmail is assumed to be present at "/usr/sbin/sendmail" if that option is used. [Kent Sibilev]
* Dropped "include TMail" as it added to much baggage into the default namespace (like Version) [Chad Fowler]
