Ubuntu 14.04.3 LTS released‏ with updated kernel and X stack

The Ubuntu team recently announced the release of Ubuntu 14.04.3 LTS (Long-Term Support) for its Desktop, Server, Cloud, and Core products, as well as other flavours of Ubuntu with long-term support. This release contains an updated kernel and X stack for new installations to support a wider variety of new hardware across all supported architectures, not just x86.

Package Updates:

Linux kernel 3.19

  • By default, the 14.04.3 point release will ship with a newer 3.19 Linux kernel from Ubuntu 15.04, and a matching X.org stack. This is based on the 3.19.0Extended Upstream Stable Kernel Release. The purpose of providing a newer kernel in the 14.04.3 point release is for hardware enablement

Python 3.4

  • We eventually intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. 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

AppArmor has a number of new features in Ubuntu 14.04 LTS LTS. Notably:

  • Support for fine-grained mediation of signal(7)
  • Support for fine-grained mediation of ptrace(2)
  • Improved DBus mediation
  • New abstractions for applications running under Unity
  • Several new tunables supporting XDG user directories, dovecot and more
  • Various policy updates in support of new features and bug fixes
