If you have already upgraded to Ubuntu 14.04 LTS there is another upgrade available to download – 14.04.1. Considering the version number, there might not be many revolutionary changes but it always pays to have the latest version of the operating system because it often comes with various patches and bug fixes. Here is what Canonical’s official statement says:
The Ubuntu team is pleased to announce the release of Ubuntu 14.04.1 LTS (Long-Term Support) for its Desktop, Server, Cloud, and Core products, as well as other flavours of Ubuntu with long-term support.
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, with a focus on maintaining stability and compatibility with Ubuntu 14.04 LTS.
