If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. The Ubuntu 14.04 LTS image continues this process, although we will not be able to convert everything to Python 3 for the Ubuntu 14.04 LTS release. We eventually intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. For more information regarding the 14.04.3 LTS Hardware Enablement Stack, please refer to: The purpose of providing a newer kernel in the 14.04.3 point release is for hardware enablement. This is based on the 3.19.0 Extended Upstream Stable Kernel Release.

To remain on the original Trusty stack, there are a few options: Those running virtual or cloud images should not need this newer hardware enablement stack and thus it is recommended they remain on the original Trusty stack. This newer hardware enablement stack will be comprised of the kernel and X stack from the Vivid 15.04 release. In an effort to support a wider variety of hardware on an existing LTS release, the 14.04.3 point release will ship with an updated kernel and X stack by default. Please test and report any bugs you find: Please see the Trusty blueprint list for details. Please ensure you have network connectivity to one of the official mirrors or to a locally accessible mirror and follow the instructions above. Offline upgrade options via alternate CDs are no longer offered for Ubuntu Desktop and Ubuntu Server. Note that the server upgrade will use GNU screen and automatically re-attach in case of dropped connection problems. Launch the upgrade tool with the command sudo do-release-upgrade. Install the update-manager-core package if it is not already installed.
