Changes since 4.1.7:

When the user clicks on the "Put in Outbox" button, a warning now pops up explaining what that button does and why the user might actually want to click on the "Send around" button instead. There is a check-box in this pop-up to prevent it from being displayed in the future. The purpose of this new warning is to help alleviate the confusion from which some users suffer about which button to click to schedule a message.

New Armenian translation. Thanks to HrantOhanyan from BabelZilla!

THIS IS THE LAST VERSION OF THIS ADD-ON WHICH WILL SUPPORT THUNDERBIRD 7 AND OLDER AND POSTBOX 2.

The next version to be released after this one will include significant new functionality which cannot be implemented within Thunderbird 2 or Postbox 2. Users who do not wish to upgrade to a newer version of Thunderbird or Postbox may continue to use this version as-is, but there will be no further bug-fix or feature releases compatible with Thunderbird 2 or Postbox 2.
