On October 11, 2006, QUALCOMM Incorporated and the Mozilla Foundation announced future versions of Eudora would be based on the Mozilla Thunderbird platform and be open source. The codename for this project is "Penelope," with that name being used for the extension provided for Thunderbird, and the Eudora name kept for all-in-one releases. Development began on November 22, 2006 with the first patch being submitted to Bugzilla. Further development of Penelope and Eudora continued, with the first beta version of Eudora 8.0 released on August 31, 2007; the most current releases, Eudora 8.0b9 and Penelope 1.0b1, were released on March 4, 2010. On June 28, 2013, the Mozilla website at Mozilla website indicated that Eudora OSE is based on an out-of-date version of Thunderbird and that current users should consider switching to Thunderbird. This implies that the project is dead.
