Korora 22 (Selina) available

It has been a long road to the Korora 22 (codename "Selina") release and we're sorry that it has taken so long. However, it is now finally available for download (we strongly recommend using BitTorrent).

First things first; a break with tradition. Being set in Australia, our releases are normally named after Finding Nemo characters, however in honour of the birth of a daughter to core contributor Maik Adamietz (DarkEra) and his wife, we've decided to name this release after her. Meet, Selina. Congratulations Maik!

Now, on with the show.

KDE 4 is no longer supported in Korora 22. If you do not wish to upgrade to KDE 5 then please stick with Korora 21.
With this release we've decided to no-longer include Adobe Flash out of the box, due to the continued high number of security flaws. The repository is still enabled, however, and if you wish to use Flash you can install it using the package manager, or command line "sudo dnf config-manager --set-enabled adobe && sudo dnf install flash-plugin" - or install and use Google Chrome which has the current up-to-date version of Flash.

Thanks to our continued support from core contributors Maik Adamietz (DarkEra) and Jim Dean (ozjd) we have been able to retain our Xfce, Cinnamon and MATE editions for another cycle. Also, a shout out to Leigh Scott (leigh123linux) for his help with Cinnamon.

Features

Derived from Fedora 221, Korora benefits from Fedora's long tradition of bringing the latest technologies to open source software users.

A complete list with details of each new inherited feature is available at the Fedora 22 Change Set page.

###Faster and better dependency management with DNF With Korora 22 we're introducing a major change under the hood; we're now using DNF and hawkey to manage packages. DNF is much like the Yum software package manager (it's largely command-line compatible), but re-written and re-engineered to provide optimal performance and (along with Hawkey) provide a strict API definition for plugins and extending projects. DNF also makes use of the libsolv library initially pioneered by the openSUSE Project to provide faster and better dependency management.

It also boasts a better performance and memory footprint vs. Yum, and is designed to have a cleaner codebase and be easier to maintain.

###Elasticsearch Elasticsearch is full-featured and very popular self-standing open source indexing server, and now it's available with just a "yum install elasticsearch" – no, wait, make that "dnf install elasticsearch" :-)

###GNU Compiler Collection 5 Korora 22 comes with GCC 5.1 as the primary compiler suite.

###Captive Portal Detection Korora GNOME, by default, enables a captive portal detection that requests known content from a trusted Fedora server. If the request is redirected, a window automatically appears for you to interact with the portal's login webpage.

To disable this feature, remove /etc/NetworkManager/conf.d/20-connectivity-fedora.conf

###Developer orientated firewall Developers often run test servers that run on high numbered ports, and interconnectivity with many modern consumer devices also requires these ports. The firewall in Korora GNOME, firewalld, is configured to allow these things.

Ports numbered under 1024, with the exceptions of sshd and clients for Samba and DHCPv6, are blocked to prevent access to system services. Ports above 1024, used for user-initiated applications, are open by default.

Refer to https://fedoraproject.org/wiki/FirewallD for details on customizing the firewall configuration, or use the firewall-config package for a graphical tool.

Cinnamon 2.6

This new release of Cinnamon targets a improvements in responsiveness, load times and CPU usage as well as various improvements under the hood. Refer to the Cinnamon release announcement for more details.

MATE 1.10

This new release of MATE continues to deliver important changes under the hood of this GNOME 2 fork. Refer to the MATE release announcement for more details.

GNOME 3.16

GNOME developers have provided many enhancements to streamline and improve the GNOME Desktop Environment. Notifications have been significantly reworked and many applications saw numerous improvements including Files, Boxes and Image Viewer. Refer to the GNOME Release Notes for more details.

KDE Plasma 5

Plasma 5, the successor to KDE Plasma 4, is now the default workspace in the Korora KDE edition. It has a new theme called Breeze, which has cleaner visuals and better readability, improves certain work-flows and provides overall more consistent and polished interface. Changes under the hood include switch to Qt 5 and KDE Frameworks 5 and migration to a fully hardware-accelerated graphics stack based on OpenGL(ES). Refer to the KDE Plasma 5.3 for more details.

Xfce 4.12

The Xfce spin has been updated to Xfce 4.12. This release has an enormous number of improvements, including HiDPI support, improvements to window tiling, support for Gtk3 plugins, and many improvements for multi-monitor support. Refer to the Xfce release announcement for more details.

But wait, there's more ...

  • Ruby 2.2 Ruby 2.2 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.1 in Fedora 21 to Ruby 2.2 in Fedora 22, alongside JRuby, Fedora becomes the superior Ruby development platform.
  • Perl 5.20 A new perl 5.20 version brings a lot of changes done over a year of development. See 5.20.0 perldelta for more details.
  • Vagrant Create and configure lightweight, reproducible, and portable development environments with Vagrant. It comes configured with the libvirt provider as a default.

Known issues

There are a few known issues with this release, which we plan to address in 22.1 or the 23 release.

  • The Anaconda installer occasionally hides the done button. To proceed, press the Alt + d key combination.
  • Xfce and MATE have some MIME type to application mismatches, such as text files to LibreOffice (instead of the text editor) and audio to VLC (instead of the music player).
  • KDE has some doubled up applications, such as LibreOffice with Calligra.
