Fedora 23 is just around the corner and it is time to buckle down and start working on the release notes. If you are interested in working on this, or you want an easy way to get more badges please take a look at the [wiki page][1] and sign up to write a beat for the release notes. If you have question on what a beat is or how to go about writing it please ask on the list, or in irc, or read the documentation on [how to write this documentation][2].

If you have worked on this in the past please visit the page and remove the asterisk (*) from your name to show that you want to work on that beat this time around.

Now your [change log][3]: (Note: I did not add a synopsis for self contained changes)

1 Fedora 23 Accepted System Wide Changes Proposals

1.1 Harden All Packages

  Hardening is the process of securing a system/application by reducing its unnecessary functions, or restricting access. In Fedora 22 and before, it was up to the package maintainer to add %global _hardened_build 1 to their spec file to ensure their program was hardened. Beginning with Fedora 23 this will now become the defaults for all packages.

1.2 Mono 4

  Update the Mono stack in Fedora from 2.10 to 4.*

1.3 Disable SSL3 and RC4 by default

  This change will disable by default the SSL 3.0 protocol and the RC4 cipher in components which use the system wide crypto policy. That is, gnutls and openssl libraries, and all the applications based on them.

1.4 Perl 5.22

  A new perl 5.22 version brings a lot of changes done over a year of development. Perl 5.22 should be released 5/20/2015. See 5.21.11 perldelta for more details about preparing release.

1.5 Default Local DNS Resolver

  To install a local DNS resolver trusted for the DNSSEC validation running on This must be the only name server entry in /etc/resolv.conf.

1.6 Fedora 23 Boost 1.59 Uplift

  This change brings Boost 1.58.0 or later to Fedora 23. We generally aim to ship 1.59.0, as that seems likely to make it (hence the Change name), but 1.58.0 is out and available now.

1.7 Glibc locale subpackaging

  This change should make it possible to install or uninstall locales individually.

1.8 SELinux policy store migration

  The newest SELinux userspace project release 2015-02-02 includes a change of the location of the SELinux policy store, which defaults to /var/lib/selinux/.

1.9 Two Week Atomic

  Fedora Atomic Host is an implementation of the Project Atomic pattern for a specialized operating system for the deployment of containerized applications. For the past two Fedora releases, we've included an Atomic Host cloud image as a non-blocking deliverable. However, upstream Atomic is moving very fast — by the end of the alpha, beta, final stabilization cycle Fedora uses, the released artifact is basically obsolete. Additionally, the Project Atomic team at Red Hat would like to do their ongoing development work in the Fedora upstream, and the six-month release cycle does not lend itself to that.

1.10 Unicode 8.0 support

  Unicode 8.0 got release on 17th June 2015. It includes 41 new emoji characters (including five modifiers for diversity), 5,771 new ideographs for Chinese, Japanese, and Korean, the new Georgian lari currency symbol, and 86 lowercase Cherokee syllables. It also adds letters to existing scripts to support Arwi (the Tamil language written in the Arabic script), the Ik language in Uganda, Kulango in the Côte d’Ivoire, and other languages of Africa. In total, this version adds 7,716 new characters and six new scripts.

1.11 IBus 1.5.11

  IBus 1.5.11 will have the features of XKB prefix language icons on the panel in KDE 5 and support $HOME/.XCompose file in all desktops.

1.12 Node.js 0.12

  Fedora 23 will be updated to Node.js 0.12, the latest release of the platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

1.13 jQuery

  jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.

1.14 Layered Docker Image Build Service

  Fedora currently ships a Docker base image, but Docker supports a layering concept. There are some applications like Cockpit which we would like to ship as layered applications.
