Qualcomm has released a free updater that updates the commercial Eudora Pro 4.0 to version 4.0.1. Although the update adds few new features, it includes numerous small fixes and tweaks, including vastly improved find performance within the Filters window, improved HTML parsing and performance, better nickname completion performance, and the capability to send copies of both styled and plain text in a single message using MIME. In addition, we recently learned of a neat feature that also exists in Eudora Pro 4.0: To see which filters have been applied to a selected message, press Shift and choose Filters from the Windows menu. Eudora responds by opening the Filters window with the applied filters selected. Although there’s nothing earth-shattering in Eudora Pro 4.0.1, the upgrade is free and the improvements are well worth the 2.3 MB download.
