Thunderbird beta 'Lanikai' released : Linux2u
Mozilla made public the first beta of Thunderbird 3 today. Code-named Lanikai and available for Windows, Mac, and Linux, the milestone makes few noticeable changes to the open-source and free desktop e-mail client. This is not surprising, though, as Mozilla Messaging announced that the goal of this release was to fix problems created by upgrading the Gecko engine that powers the program.
Lanikai is the first semi-stable release of Thunderbird to use Gecko 1.9.2, which is the same engine that Firefox 3.6 uses. The changes made from Thunderbird 3 to the 3.1 beta test version include Mac OS X 10.6 upgrade path from Thunderbird 2 improvements, fixes for autocomplete, tabs, activity manager, minor interface improvements and corrections, and a spate of stability and memory corrections.
One new security feature is that Lanikai requires extensions to come from a secure server using the HTTPS protocol or be digitally signed. Absent either of these, the extension won't install.
