- Replace 'utf_8' encoding name with preferred spelling ('utf-8').
- Replace 'latin_1' encoding name with preferred spelling ('iso-8859-1')
- Include the time of the error when logging errors from the queue processor.
- response.MIMEPart now correctly sets the charset of the email payload if it's
one of the content_type parameters of the Message or Attachment.
- The SMTPMailer now accepts an "ssl" argument, which, if passed, will cause
the SMTP factory to return an SMTP_SSL connection instead of a plain old
SMTP connection.
- The SMTPMailer now uses a 10-second timeout by default, used when an
SMTP connection is made but the server does not respond in enough time.
