The open source version of Eudora is now available for download, three months after the e-mail client stopped selling...
The Mozilla Foundation released the first beta version, 8.0.0b1, of the revised Eudora e-mail application. The new version of Eudora is being developed under the codename "Penelope" and the project is being led by the former Qualcomm team, including original developer Steve Dorner. A full replacement version of Eudora is not expected until 2008, at the very earliest.
On October 11, 2006, Qualcomm announced that future versions of Eudora would be based on the same technology platform as Mozilla Thunderbird and be open source.
The Qualcomm Penelope developers announced in July: "We currently have, in house, our first actual Beta build, called Eudora 8.0.0b1. We will probably get this posted in the next few weeks." This open source, Thunderbird-based version has been under development since 2006, but will not be a true replacement for the current Eudora in terms of features and capabilities until 2008 at the earliest.
