A release candidate for Mercury/32 v4.71 is now available at http://community.pmail.com/files/folders/mercbetas/default.aspx. We intend to make this available only at the community site for a week or so before releasing it on an unrestricted basis.
The big news in v4.71 is the ability to run as a native Windows Service: we (the test team) have been using it extensively in this mode for quite some time and it's really quite cool. There are quite a few other small new features in there, and over 200 fixes and corrections.
Feedback is welcome in the Mercury beta forum here.
