|On this day a new version of Firefox has been released, known as Firefox 7, whose most resonant characteristic is undoubtedly the decrease [even more] of the consumption of RAM.
However, Mozilla's have decided that their e-mail client will also adapt to the, #sometimeschaotic, new release cycle.
Syndicated these days as the successor to Evolution within Ubuntu (and officially present in so many other GNU / Linux distributions) This new version is not presented with primarily visual characteristics, such as a redesign of its interface, no that no.
Keep in mind that by having versions so short in time, the improvements will not be noticeable, the idea, and what has been reflected in Mozilla products, are gradual improvements.
The improvements are within, for example, the use Mozilla Gecko 7 engine and inclusion of security and stability improvements and small improvements in the interface, making working with e-mails simpler.
Likewise, a nice amount of Add-ons have been updated to work properly with Thunderbrid 7; among them: Lightning Calendar, Conversation View and Open Search, available from the Plugin Manager.
We just passed by Download Center and ready. Regarding GNU / Linux distributions, they will surely be updating the repositories shortly; for PPA-compliant distributions, they can use both: ppa: mozillateam / thunderbird-stable for the stable version or ppa: mozillateam / thunderbird-next for the, # neverappear, betas.
