* I think there is some useful as well as effective wording in Dennis Gilmore's "Announcing the release of Fedora 15 Alpha!!" at http://lists.fedoraproject.org/pipermail/announce/2011-March/002932.html which will help enhance some of these features' content.  DBR, March 10th, 2011.  :)

These are the Talking Points for the Fedora 15 release. For information on how these talking points were chosen, see Talking Points SOP. They are intended to help Ambassadors quickly present an overview of highlighted features when talking about the release.

The talking points are based in part on the features for this release. Any Fedora community member can introduce a feature, using our feature process.

Contents

[edit] For desktop users and everyone

Things of general interest to most people using Fedora.

[edit] GNOME 3 Feature

GNOME 3 feature

GNOME 3 is the next major version of the GNOME desktop. GNOME 3 brings a fresh look and feel with gnome-shell, which is a compositing window manager and desktop shell. It replaces the GNOME 2 desktop shell, which consisted of metacity, gnome-panel, notification-daemon and nautilus. Apart from pure window management, gnome-shell provides the top bar on the screen, which hosts the 'system status' area in the top right, a clock in the center, and a hot corner that switches to the so-called 'overview' mode, which provides easy access to applications and windows.

Additional information is available at the Gnome 3 website.

GNOME 3 is a major rewrite of the GNOME desktop.

[edit] LibreOffice Feature

LibreOffice feature

LibreOffice(R) is an office productivity suite that will replace OpenOffice(R). It will be completely open source and driven solely by the community supporting it. It has a word processor, presentation creator, spreadsheet creator, database creator, formula editor, and drawing editor.

Additional information is available at the Document Foundation Website.

LibreOffice is the Next generation of Free Office Productivity software.

[edit] Power Management Feature

Power Management feature

Go Green. Power Management improvements include the PowerTOP tool, which identifies the software components that make your computer use more energy than necessary while idle. Automatic tuning of power consumption and performance helps conserve on laptop battery usage, too!

Additional information is available on the Fedora Power Management SIG wiki page.

Power management features in Fedora 15 generate better efficiency and power usage for both desktops and laptops.

[edit] Tryton Feature

Tryton feature

Tryton is a three-tier high-level general purpose application platform, providing solutions for accounting, invoicing, sale management, purchase management, analytic accounting, and inventory management.

Further documentation is available on the Tryton Documentation web page.

Tryton provides applications for business management.

[edit] For administrators

Improvements that make system administrators' lives better.

[edit] Consistent Network Device Naming Feature

Consistent Network Device Naming feature

Servers often have multiple Ethernet ports, either embedded on the motherboard, or on add-in PCI cards. Linux has traditionally named these ports ethX, but there has been no correlation of the ethX names to the chassis labels - the ethX names are non-deterministic. Starting in Fedora 15, Ethernet ports will have a new naming scheme corresponding to physical locations, rather than ethX. Ethernet ports embedded on server motherboards will be named em<port_number>, while ports on PCI cards will be named pci<slot_number>p<port_number>, corresponding to the chassis labels. Additionally, if the network device is an SR-IOV Virtual Function or has Network Partitioning (NPAR) capability, the name will have a suffix of _<virtual_function> or _<partition>.

By changing the naming convention, system administrators will no longer have to guess at the ethX to physical port mapping, or invoke workarounds on each system to rename them into some "sane" order.

This feature affects all physical systems that expose network port naming information in SMBIOS 2.6 or later (specifically field types 9 and 41). Dell PowerEdge 10G and newer servers (PowerEdge 1950 III family, PowerEdge R710 family, and newer), and HP ProLiant G6 servers and newer are known to expose this information, as do some newer desktop models. Furthermore, most older systems expose some information in the PCI IRQ Routing Table, which will be consulted if information is not provided by SMBIOS.

Additional information is available at the Documentation.

Consistent network device naming based on BIOS-provided port names.

[edit] Dynamic Firewall Feature

Dynamic Firewall feature

Fedora 15 adds support for an optional firewall daemon, FirewallD, which provides a dynamic firewall management with a D-Bus interface. Unlike the current firewall model, which requires a complete firewall restart for every change, the firewall daemon manages the firewall dynamically, and can apply changes without restarting the firewall. The daemon can also provide information about the current firewall settings via D-Bus, and accepts changes via D-Bus using PolicyKit.

Additional information about the Dynamic Firewall Feature can be seen on the FirewallD wiki page.

The Dynamic Firewall daemon allows changes to firewall configuration without downtime.

[edit] Improved Compression for Live Images Feature

Improved Compression for Live Images feature

Fedora 15's live images are now built using xz, a variant of LZMA, a compression technology. xz typically provides better compression than gzip, but still provides relatively fast uncompression, which makes it suitable for building live images. As a result, Fedora 15's live images are now able to accommodate more data than ever.

To read more about the improved compression technology in Fedora 15 live images, see the feature page for live image compression in Fedora 15.

Improved compression technology allows Fedora to get more data into live images.

[edit] systemd System and Session Manager Feature

systemd System and Session Manager feature

systemd System and Session Manager feature description.

systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit. For more information, watch the available videos.

Additional information is available at the SysVinit to Systemd Cheatsheet.

systemd is the new, cutting-edge system and service manager used in Fedora 15.

[edit] For developers
