Changes

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.
OpenPGP Applet now has a shortcut to the gedit text editor, thanks to Ivan Bliminse.
Paperkey lets you print a backup of your OpenPGP secret keys on paper.

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.
Tor Browser 4.5 now keeps using the same Tor circuit while you are visiting a website. This prevents the website from suddenly changing language, behavior, or logging you out.
Disconnect is the new default search engine. Disconnect provides Google search results to Tor users without captchas or bans.
Better support for Vietnamese in LibreOffice through the installation of fonts-linuxlibertine.
Disable security warnings when connecting to POP3 and IMAP ports that are mostly used for StartTLS nowadays.
Support for more printers through the installation of printer-driver-gutenprint.
Upgrade Tor to 0.2.6.7.
Upgrade I2P to 0.9.19 that has several fixes and improvements for floodfill performance.
Remove the obsolete #i2p-help IRC channel from Pidgin.
Remove the command line email client mutt and msmtp.

There are numerous other changes that might not be apparent in the daily operation of a typical user. Technical details of all the changes are listed in the Changelog.
