Other changes include new versions of Firefox, Chrome, Thunderbird, and LibreOffice.
Because this release includes newer/bigger versions of a variety of apps, the overall install size of the base image has (by necessity) been increased to 5 Gb (see http://ubermix.org/customization.html for a better understanding of the base image.) While all prior 1.x versions have had the ability to be updated in-place, without reformatting the disk or losing user data, the increased size of the ubermix 1.4 image will require a reformat of the disk. Please bear this in mind when installing on top of an existing install, and be sure to backup any data as necessary prior to installing.
Also, due to the increased size, a 2 Gb USB install key is no longer sufficient to hold the image. Therefore, the next logical size (4Gb) is recommended for USB keys.
Support for Ubuntu 12.04 LTS stretches into 2017 and as such, so does ubermix. ubermix 2.0 will be based on the next LTS release, Ubuntu 14.04, which is due this April. Expect ubermix 2.0 (codename: honeybadger) beta releases shortly after that.
