Ubuntu 12.04 LTS BETA 2 has just been released and it now available for download.
The BETA 2 is the last official release in the Precise development cycle, although release candidates are to probably land in the “open” for final testing days before the final release.
****************the stable and final version Long Term Support is expected on April 26.
Precise Pangolin BETA 2 introduces (since the BETA 1 version) a “fixed” Unity, meaning the visual bug present in both Ubuntu 11.10 and 12.04 pre-BETA 2 (the ghost-ish effect present in Dash’s icons) has been removed, thus Unity features now a clear/clean way of displaying icons.
The Precise Pangolin edition has been improved for low-power consumption, so now along with its new features and business-related support it may be the smartest choice for be implemented on laptops, keeping in mind that Canonical has already plans for Ubuntu on mobile devices.
Ubuntu 12.04 Precise Pangolin Beta 1 comes with the 3.2.0-17.27 Ubuntu kernel, which is based on the latest 3.2.6 Linux kernel, a feature that allows developers to work more easily on the maintenance for the period of five years of the LTS plan, for both server and desktop editions.
The Unity desktop interface (implemented from the version 11.04) now has reached the version 5.4 on Ubuntu’s beta 1 stage, with new options for system settings in “Appearances” and a quick search ensured by pressing the “Alt” key from the keyboard.
As you already know from the previous releases, Ubuntu 12.04 Precise Pangolin comes by default with the Rhythmbox media player (unlike Banshee in 11.04), that includes support for the Ubuntu One Music Store.
The new goodies coming in the beta 1 edition include the latest version of LibreOffice 3.5 and a brand new beta of Firefox 11.0, and hardware support for ClickPads.
For those who are using alternative versions of Ubuntu, we might add that the beta versions of Kubuntu 12.04 LTS and Xubuntu 12.04 are already in beta version 1 too, so you may download it for testing purpose in no time.
The name “Precise Pangolin” was announced by Shuttleworth on 5 October 2011. Unlike previous LTS releases that have been supported for three years for the desktop version and five years for the server version, this release will be supported for five years on both.
Ubuntu 12.04 Beta 1 is a long-term support release (LTS) that introduces a new set of images for the ARMv7 “hard float” ABI, denoted as armhf, among other new features.
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 Ubuntu team reports in a blog. “The team has been hard at work throughout this cycle, introducing new features and fixing bugs.”
Some of the listed changes in Ubuntu include an updated LibreOffice (3.5 beta 2) and a switch to Rhythmbox as the default music player (which includes the UbuntuOne music store). Users also have access to a new HUD which provides a context-sensitive menu and search interface for Unity applications. Actual Unity settings can now be configured by the System Settings panel, and Nautilus support has been added to the Unity launcher.
The new version of Ubuntu also provides enhanced support for ClickPad devices. Now when a button is pressed on the trackpad surface, a second finger may be used to drag the cursor. Canonical’s Ubuntu Core has also been updated to include ARM hard float (armhf) images. Developers can use Ubuntu Core as the basis for their application demonstrations, constrained environment deployments, device support packages, and other goals.
“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 blog states.
