In Pictures: Ubuntu 14.04 LTS

Ubuntu 14.04 LTS, or Trusty Tahr, is here The first long-term-support release of the popular Linux-based Ubuntu operating system since 2012’s Precise Pangolin (version 12.04) has arrived. Here’s a look at a few things that have changed in that time.
Better window menus, anti-aliasing Local integration for menus means that those important drop-downs no longer get exiled to the top of the screen, appearing instead on the title bar. Also, their corners should look smoother, thanks to the use of GTK3, rather than the older Compiz plugin, to draw them.
New lockscreen It’s over on the LEFT now, in another new Unity twist.
Pollinate New to Ubuntu 14.04 is Pollinate, an ingenious cloud-based pseudo-random number generator, which pulls entropy from a remote source. Creator Dustin Kirkland calls it “entropy-as-a-service.”
Secure filesystem capabilities enabled by default Enabling modern, secure systems for handling selective privileges makes those privileges less easily abused by malicious actors. Think of it like legal online music services – it’s providing an easier way to get things done, with the additional benefit that it’s also safer.
High DPI optimization Canonical says that Ubuntu 14.04 will feature improved support for displays with high pixel density – which could prove important as 4K screens begin to gain traction in the market.
