Tails, The Amnesic Incognito Live System, version 1.4, is out.

This release fixes numerous security issues and all users must upgrade as soon as possible.

New features

Tor Browser 4.5 now has a security slider that you can use to disable browser features, such as JavaScript, as a trade-off between security and usability. The security slider is set to low by default to provide the same level of security as previous versions and the most usable experience. We disabled in Tails the new circuit view of Tor Browser 4.5 for security reasons. You can still use the network map of Vidalia to inspect your circuits.

Upgrades and changes

Tor Browser 4.5 protects better against third-party tracking . Often when visiting a website, many connections are created to transfer both the content of the main website (its page, images, and so on) and third-party content from other websites (advertisements, Like buttons, and so on). In Tor Browser 4.5, all such content, from the main website as well as the third-party websites, goes through the same Tor circuits. And these circuits are not reused when visiting a different website. This prevents third-party websites from correlating your visits to different websites.
