I have just tagged alot v0.9; You can get a tarball here .
Again there were mostly under-the-hood fixes and refactoring.
The most significant new feature set is the ability to send HTML emails,
which works quite nicely in combination with pandoc  as documented here .
Usage updates since v0.8:
* feature: interpret ANSI escape codes (e.g.for colours) when displaying messages
* config: configure message-id domains for each account
* feature: new envelope commands txt2html, html2txt, removehtml
* info: updated signature of hooks 'reply_prefix' and 'forward_prefix', now include a named parameter for the message being replied/forwarded
As usual, a quick hall of fame of recent contributors:
$ git shortlog -s -n 0.7...
