Codenamed “Precise Pangolin”, 12.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work throughout this cycle, introducing new features and fixing bugs.
This release introduces a new set of images for the ARMv7 “hard float” ABI, denoted as armhf. There are still some armel images around, as we finish the migration, but 12.04 for ARM will be based on armhf.
The technology that allows GPUs to go into a very low power consumption state when the GPU is idle (RC6) is now enabled by default for Sandy Bridge systems, which should result in considerable power savings when this stage is activated.
The CD image size has been adjusted to 703MB to squeeze in every bit of package goodness we can on the installation CD images.
With Ubuntu 12.04, Kubuntu, Edubuntu, Xubuntu, Lubuntu, and Ubuntu Studio also reached Beta 1 status today.
Some of the new features now available are:
A new way to quickly search and access any desktop application’s and indicator’s menu, called the HUD, can be accessed by taping the Alt key and entering characters.
Unity setting can now be configured by the System Setting panel, and Nautilus support has been added to the Unity launcher.
Support for ClickPad devices has been enhanced an now when a button is pressed on the trackpad surface, a second finger may be used to drag the cursor.
The default music player has been switched to Rhythmbox, which again includes the UbuntuOne music store.
LibreOffice has been updated to 3.5 beta 2. Please report any regressions that you notice.
When installing packages through the software center, the corresponding language support packages are now installed automatically as well.
