The postmark Ruby gems have been updated to version v0.9 and v0.4 respectively, offering improved compatibility with both Rails 2.3 and Rails 3, as well as enhanced support for attachments in mail messages. The new gems can now be used with Mail instead of Tmail when not paired with Rails. Additionally, the developer documentation has been updated to include libraries for CakePHP and Node.js. Significant contributions were made by Randy Schmidt, David Pitman, Chris Williams, and Daniel McOrmond.
