A new point release of the Xenial Xerus LTS has been released. As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs. Please see the 16.04.1 change summary for more information.
Users of Ubuntu Studio 14.04 will soon be offered an automatic upgrade to 16.04.1 via Update Manager. For further information about upgrading, see: https://help.ubuntu.com/community/XenialUpgrades
