Formally presented to release Linux-Fedora distribution 15. Of the key improvements in Fedora 15, we can note the transition to the system manager systemd, change the names of network interfaces, integration of desktop environments GNOME 3 obolochnoy GNOME Shell, assembling packages with GCC 4.6, the use of Linux-kernel 2.6.1938, adding the implementation of a dynamic firewall involvement default DNSSEC and a move to the directory /run" instead of "/var/run".

The main innovations introduced in Fedora 15:

User
* Integration of GNOME graphical environment 3 and the use of the default shell GNOME Shell. An overview of innovation GNOME 3 can be found here. Additionally, distribution assemblies are available with graphical environments KDE 4.6 and Xfce 4.8;
* Use instead of the OpenOffice.org office suite LibreOffice;
* The package includes the latest version of the training envelope Sugar 0.92;
* Use the Firefox web browser 4, comes with a fully open Java-plugin IcedTea-Web;
* Update the video drivers: Intel 2.14.0 c support Sandybridge; Radeon 6.14.0 with support for 2D, 3D and videoakseleratsii for GPU Evergreen, as well as 2D and videoakseleratsii for GPU Northern Islands; Nouveau supports 2D, 3D and videoakseleratsii for GPU Fermi;
* Use X.Org-server 1.10 and prior versions of Mesa 7.11;

Developer
* Integration with the distribution Python 3.2 and newer versions of Rails (3.0.3) and OCaml (3.12). Upgrading the Boost library to version 1.46;

* Update debugger GDB to version 7.3 (release not yet released), the inclusion of a set of compilers, GCC 4.6;

System changes
Integration System Manager systemd as a system initialization by default. Systemd aimed at more intensive parallelization service execution at boot system, having incorporated the best features of systems such as launchd (Mac OS X), SMF (Solaris) and Upstart (Ubuntu, Fedora). In addition to launching services, systemd provides the functions of monitoring of the background processes.

Migrating "/ run" from the directory "/ var" to the root in order to solve the problem with inaccessibility of / var / run early in boot.

Changing the names of network interfaces. Instead ethN device names will emerge depending on the type of connection network adapter: "em {port}" - embedded in the motherboard and network card "pci {slot} # {port}" - card with PCI-interface.

Switching to GCC 4.6 for packaging;

Improving the operation of the power management system, support for automatically tuning the parameters of the system, to ensure optimal balance between performance and power consumption. Integration Center PowerTOP 2.0 to identify bottlenecks that lead to increased energy consumption;

Enabling compression system XZ for the formation of Live-images of reduced image size by 10%;

Adding LessFS, FUSE-module for the automatic association of duplicates in the files;
Update RPM Package Manager to version 4.9, which includes support for plug-in generator and built-in dependency filtration generated curves, increased productivity;

Switching to Linux-kernel 2.6.1938.

In the installer used on the installation DVD, the menu adds the ability to install with the file system Btrfs (previously demanded the transfer of the special installer options)

Separately, the continuation of work on utility btrfsck, designed to restore the integrity of damaged Btrfs-sections, and the improvement of the plugin yum-plugin-fs-snapshot, allowing the system returned to its original state after a failed install or upgrade packages. It is reported that the developers are considering using Btrfs as the default file system is already starting with the next release (Fedora 16).

Virtualization and Security
Adding DynamicFirewal, the background process for dynamic management of packet filter rules via DBus. Using DynamicFirewall will make changes to your firewall without having to reboot without breaking the rules and established connections. To dynamically control the firewall provided utility firewall-cmd, which greatly simplifies the creation of rules, proceeding not from the IP-addresses of network interfaces and port numbers, and names of services (for example, to open the service access samba for 90 seconds, you can "firewall -cmd - enable - service = samba - timeout = 10 ").

In Fedora 16 will create additional graphic tools. In the long term (Fedora 17) will implement an interactive mode locking, which in the event of unauthorized external requests from local applications or access from outside to network services, the user displays an interactive form with a proposal to accept or reject the request with the possibility of opening up access only at certain times ;

C to enhance security, all setuid-applications will be downgraded to the "capabilities", allows you to selectively organize the execution of preferred only required action. For example, the ping utility will be able to access only the raw-socket (CAP_NET_RAW), without delegating the remaining root-right;
Integration BoxGrinder, a tool to facilitate the formation of assemblies for deployment within the different virtualization (KVM, Xen, EC2);

Improved support for Encrypting File System eCryptfs. Use authconfig to automatically mount the encrypted portion of your home directory when a user login;

Using the default DNSSEC configurations of workstations. For name in NetworkManager uses DNS-Server BIND;

Technology Support Spice in virt-manager;

GUI-interface Setroubleshoot redesigned to simplify diagnosis of problems with SELinux.
