<p><b>Mercury/32 v4.51 is now publicly available.</b> Although on the surface v4.5 will not appear markedly different from v4.01, "under the hood" it's quite a different story. The code has been heavily reworked in almost every area, focusing heavily on robustness, reliability and performance. A download link and list of new features in v4.5 is available at     http://www.pmail.com/m32_451.htm Starting with this release of Mercury, the licensing model for the program has changed. Mercury remains completely free for non-commercial use, but commercial users will need to purchase a license if they wish to continue using it after a 60-day evaluation period. We have attempted to produce a licensing program that is both very inexpensive, and completely non-intrusive. Details and pricing can be found here:    http://community.pmail.com/pmail/MercuryPricing.aspx Please note that if you have a current support subscription at any level under the old Pegasus Mail Support Consortium arrangement, you are automatically entitled to a Mercury site license at no charge - please contact me directly to arrange this. A personal note: I'm acutely conscious that it has taken an abnormally long time to get this release done. One of the lessons I have learned from the problems in getting v4.5 complete is that I need to open up the beta testing process so that more people have greater access to betas and patches more often. I will be developing a strategy for this over the next couple of weeks. Any problems or issues arising from this release can be raised either on the public mailing list at bama.ua.edu, or in the Community forums at our community web site, http://community.pmail.com.
