From the Go Get 'Em dept.:
The Ubuntu team is pleased to announce the release of Ubuntu 12.04.4 LTS (Long-Term Support) for its Desktop, Server, Cloud, and Core products, as well as other flavours of Ubuntu with long-term support.
As with 12.04.3, 12.04.4 contains an updated kernel and X stack for new installations on x86 architectures.
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 12.04 LTS.
Kubuntu 12.04.4 LTS, Edubuntu 12.04.4 LTS, Xubuntu 12.04.4 LTS, Mythbuntu 12.04.4 LTS, and Ubuntu Studio 12.04.4 LTS are also now available.
