Fedora 27 talking points

This is a draft!

These are the Talking Points for the Fedora 27 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, and to help drive content for the release, etc.

The talking points are based in part on the Change Set for this release.

Overall Release Story

Since we skipped the Alpha release for this cycle we just push out the Beta. We had some delays to grant the best stability and operability for our users. The release date is 2017-10-03.

For this cycle, the server edition won't be shipped at the same time due to big changes happening inside the edition itself. This is due to the major change of building the server edition with modularity. For more informations, please read the Fedora Magazine article

Here's the beta release announce

Fedora 27 Accepted System Wide Changes Proposals

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 27 Release as System Wide Changes.

32 bit UEFI Support

Some x86 systems ship with a 64 bit CPU, but 32 bit UEFI firmware. It is possible to use a 32 bit UEFI grub build to boot a 64 bit kernel and distribution on these systems. So far this setup has not been supported in Fedora. This feature is about adding support for installing and booting Fedora on this hardware.

Arbitrary Branching

Tooling changes to support the new way of branching for Fedora 27

Drop 256term.sh

Do not install /etc/profile.d/256term.sh and /etc/profile.d/256term.csh.

Enable TRIM pass down to encrypted disks

Override kernel default for dm-crypt mappings of LUKS1 encrypted volumes via flag put in /etc/crypttab file. This change should affect only newly created encrypted storage based on LUKS1 format during installation.

Fedora 27 Boost 1.64 upgrade

This change brings Boost 1.64.0 to Fedora 27. This will mean F27 ships with a recent upstream Boost release.

The GNU C Library version 2.26

Switch glibc in Fedora 27 to glibc version 2.26.

Host and Platform

Host and Platform is an evolution of the Base Runtime module concept introduced in Fedora 26 Boltron, splitting the minimal system further into independent modules allowing for greater flexibility when composing and maintaining the base system.

Kerberos KCM credential cache by default

Default to a new Kerberos credential cache type called KCM which is better suited for containerized environments and provides a better user experience in the general case as well.

Modular Server

The Modularity Working Group, Factory 2.0, Base Runtime, and Server Working Group would like to propose using the modular infrastructure for creating and delivering the Fedora Server Edition for Fedora 27. While we are still working through some of the kinks leading up to the release of Fedora 26, we believe that the changes to the infrastructure and technology implementations will be available with sufficient time to harden the components in time for the 27 release.

Modular Release

The build, release, distribution, and update changes associated with and required for the Changes/Modular_Server and Changes/Host_and_Platform Changes.

No More Alphas

Fedora will no longer produce Alpha releases.

• Status: 100% code completed

Node.js 8.x

Fedora 27 will be updated to Node.js 8.x, the latest LTS release of the platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

Parallel Installable Debuginfo

debuginfo packages can be installed in parallel to make it easier to trace, profile and observe what programs are doing or to debug when they have crashed. That way debugging, tracing or profiling programs can be done independent of whether they are 32bit, 64bit, a slightly newer or older version than currently installed or even from a different architecture.

RPM 4.14

Update RPM to the upcoming 4.14 release.

Ruby on Rails 5.1

Ruby on Rails 5.1 is the latest version of well known web framework written in Ruby.

Separate Subpackage and Source Debuginfo

Allow to install just the debuginfo for a subpackage and/or without the source files. The debuginfo packages are huge because they contain debuginfo and all sources for all subpackages. Being able to install only the debuginfo for the subpackage that is installed reduces the size that needs to be downloaded to analyze, trace, profile or debug a program or core file. Some tracing and profiling tools don't need the actual source files to provide stack traces or insert probes. So installing the debugsources should be optional.

Golang 1.9

Rebase of Golang package to upcoming version 1.9 in Fedora 27, including rebuild of all dependent packages(pre-release version of Go will be used for mass rebuild).

Switch libcurl back to OpenSSL

libcurl in Fedora currently uses the NSS (Network Security Services) library for TLS and cryptography. After implementing this change, libcurl will use OpenSSL instead of NSS.

perl Package to Install Core Modules

dnf install perl will install all core Perl modules that come with Perl upstream sources.

Perl 5.26

A new perl 5.26 version brings a lot of changes done over a year of development. Perl 5.26 was released 5/31/2017. See 5.26.0 perldelta for more details about preparing release.

Fedora 27 Accepted Self Contained Changes Proposals

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 27 Release as Self Contained Changes.

Bodhi Non-RPM Artifacts

Bodhi, the Fedora Updates System, should be able to process more than just RPMs.

Chinese Serif Fonts

Fedora already provides default Chinese Sans fonts, now Fedora 27 will also provide default Chinese Serif fonts.

Decouple system java setting from java command setting

By default, Java applications installed from RPMs are run with JVM found on PATH. We propose to run them with default system JVM, not considering PATH. Users will still be able to override the default using JAVA_HOME environment variable as before.

Improved Bay- and Cherry-Trail device support

Improve support for hardware using Intel Bay Trail and Cherry Trail SoCs.

Java 9

Add a tech preview preview of the the upcoming version of Java (OpenJDK9) to Fedora 27

Making sudo pip Safe (Again)

At the present time, running sudo pip3 in Fedora is not safe. Pip shares its installation directory with dnf, can remove dnf-managed files and generally break the Python 3 interpreter. We propose a series of measures that will make it safe to use.

New default cipher in OpenVPN

Since the discovery of the SWEET32 flaw, ciphers using cipher-blocks smaller than 128-bits are considered vulnerable and should not be used any more. OpenVPN uses Blowfish (BF-128-CBC) as the default cipher, which is hit by the SWEET32 flaw. This proposal changes the default cipher to AES-256-GCM while in parallel allowing clients to connect using AES-256-CBC, AES-128-CBC or the deprecated BF-CBC,

OpenSSH Server Crypto Policy

OpenSSH clients follow the system-wide crypto policy since Fedora 26. This F27 change modifies the openssh server configuration to adhere to the system-wide policy. That will allow openssh server configuration to adapt to the multiple security levels offered system-wide.

Platform Python Stack

A revisit of the System Python change from Fedora 24. It has been renamed from System Python to Platform Python not to collide with upstream PEP 432.

Remove SSH-1 from OpenSSH clients

Upstream removes support for SSH-1 protocol and we plan to do the same in Fedora. The protocol is years obsolete and not even supported in current default binaries (only in openssh-clients-ssh1 subpackage).

Remove krb5-appl

Remove src:krb5-appl (produces packages krb5-appl-clients and krb5-appl-servers) from the distribution.

Replace Yumex-DNF with dnfdragora

Replace the current alternative graphical package manager.

Samba AD

Samba AD is an open source implementation of an Active Directory set of tools and protocols. It allows Windows clients to be enrolled and managed using native Windows tools. In addition, Samba AD can serve as a domain controller for Fedora workstations and servers utilizing DCERPC, LDAP and Kerberos.

aarch64 SBC (Single Board Computer) Disk Images

We will deliver the first supported SBC disk images for aarch64.

libpinyin 2.1

libpinyin 2.1 will merge libzhuyin code and replace the package

Editions

Fedora Atomic

• Consolidated Storage Setup based on OverlayFS - In Fedora Atomic 27 we now default to a more simple container storage setup. In Fedora 26 we switched to overlay as the default driver but we still had a separate volume to for this storage. While we do recommend the separate volume for production deployments we also want a more simple setup for the out-of-the-box experience. In Fedora 27 Atomic Host the default will be a large root filesystem, shared with the container storage (via overlayFS).
• Containerized Kubernetes by Default - Fedora Atomic 27 no longer includes Kubernetes, etcd, or flannel in the base OSTree. We offer containerized Kubernetes, flannel and etcd. This allows flexibility for users to choose different versions of Kubernetes, or to not use Kubernetes at all. If having kubernetes installed via RPM is a requirement, then package layering is still an option.
• Improvements in Package Layering - Latest rpm-ostree, now with support for base package overrides (removes and replaces). This builds on top of the previous features including support for direct rpm install, and experimental LiveFS layering, which allows layering without a reboot.
• System Containers in FLIBS - System Containers, a way of installing system infrastructure software via a container. Since Fedora 26 we have polished the System Container technology and now offer System Containers for Docker, Kuberetes, Flannel, and etcd. These are all available in the Fedora Layered Image Build Service.
• atomic 1.19.1 - An updated to Atomic CLI version 1.19.1, with enhancements/bugfixes to system container support.
• Cockpit 149-1 - Latest version of Cockpit, including support for Cockpit Dashboard installation on Atomic Host via rpm package layering.

Fedora Server

For this cycle, the server edition won't be shipped at the same time due to big changes happening inside the edition itself. This is due to the major change of building the server edition with modularity. For more informations, please read the Fedora Magazine article

      • CSV export settings are now remembered
      • Priority of conditional formatting rules can be changed with new up/down buttons.
      • New cell comment commands added
      • While building formulas, when selecting a cell or range on another sheet with the pointer, absolute sheet references are now created instead of relative
      • Support negative year date (BCE) in cell input and date display
      • A new Cell Protection toggle command was added to Edit ▸ Cell Protection to change the protection status of the cell
      • Four new sheet protection options have been added to optionally allow insertions and deletions of rows and columns.
      • New function ROUNDSIG to round a value at a number of significant digits
      • The semantics of the COUNTIF, SUMIF and AVERAGEIF Criteria argument has been changed.
