Summary of main program changes in Ubuntu 14.04 LTS

Over the past few weeks we have discussed the major updates to the operating system for Ubuntu's first lts new version over the past two years. Today we're going to list the main application updates from the Ubuntu App Store since the last LTS version.

Major Programs and tools updates

In addition to a large number of desktop application updates (discussed in the next section), a large number of other programs and tools have been updated very well over the past two years. Some of the following are discussed in part:

Xen 4.4 is a major update for Ubuntu's built-in Xen. The most significant change is that it no longer supports a pure 32-bit CPU (although it continues to support 32-bit operating systems). This should not be a big problem, since most CPUs have been 64-bit over the past six years. But that means people who still use Ubuntu on old servers or notebooks need to know that Xen will no longer support their CPUs.

QEMU 2.0 shortly after Xen introduced QEMU, because some adjustments were made to accommodate xen,qemu. The main effect is that the virtual machines created in the KVM cannot be migrated from the previous Ubuntu 12.04 to this version, and the snapshots cannot be recovered. In addition, binary virtualization of arm64 is added.

MySQL is installed by default MySQL 5.5, but can also be installed from the standard library Percona, mariadb or MySQL 5.6. Surprisingly, unlike other mainstream distributions, Ubuntu does not replace the database with MARIADB and continues to install MySQL by default. I guess it's a better relationship with Oracle.

Apache 2.4 and PHP 5.5 is a bit of a surprise that Apache upgraded to version 2.4, after all, the 2.2 version has been used steadily for too long. But I'm glad to see that the mainstream distribution is able to keep up with the new version. PHP can be upgraded to PHP as early as 12.04 LTS 5.5, but the new version of the system has been installed by default PHP 5.5. Note: If you are using some boss CMS platform (Um, like Drupal), you may have to make some adjustments during the upgrade process, please refer to the documentation.

Software Center: Desktop application upgrades

In short, the main software centers have a number of major updates (after all, two years from the previous version). The most obvious software updates are as follows:

Google Chrome 33

Firefox 28

Nautilus 3.10

The gimp–2.8

KDE 4.13 (I think it's the best desktop environment)

Although not mentioned above, office kits have been pre-installed LibreOffice 4.2.3.3, looks great, do not believe that you see:

Summarize

In short, Ubuntu 14.04 LTS successfully from 12.04 smooth transition. Unless you're unlucky, using the latest version of the NVidia graphics card (a Linux dedicated driver with a 780GTX or Titan chip is not integrated into the system).

In the following articles, I'll delve into more technical details about the monitor and video card (better for high-resolution displays) and an early preview test for Mir (xwindows Desktop replacement Software) (in the virtual machine environment, of course). If there's anything else you'd like to know, leave a message in the comment box and we'll see you next week!
