The following Python and Ruby updates are available for CentOS:

Announcing release for Python 2.7, 3.3 and 3.4 on CentOS Linux 6 and 7 x86_64 SCL
Announcing release for Ruby 1.9.3, 2.0.0, 2.2 and Ruby on Rails 3.2, 4.0, 4.1 on CentOS Linux 6 x86_64 SCL

Announcing release for Python 2.7, 3.3 and 3.4 on CentOS Linux 6 and 7 x86_64 SCL

I am pleased to announce the immediate availability of versions 2.7, 3.3
and 3.4 of the Python on CentOS Linux 6 x86_64 and CentOS Linux 7
x86_64, delivered via a Software Collection (SCL) built by the SCLo
Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo).

QuickStart
----------
You can get started in three easy steps (example of Python 3.4):
$ sudo yum install centos-release-scl
$ sudo yum install rh-python34
$ scl enable rh-python34 bash

At this point you should be able to use python just as a normal
application. An examples of commands run might be:
$ python my-app.py
$ easy_install Flask
$ easy_install Django
$ bundle

In order to view the individual components included in this
collection, including additional python modules, you can run:
$ sudo yum list rh-python34\*

About Software Collections
--------------------------
Software Collections give you the power to build, install, and use
multiple versions of software on the same system, without affecting
system-wide installed packages. Each collection is delivered as a group
of RPMs, with the grouping being done using the name of the collection
as a prefix of all packages that are part of the software collection.

The collections rh-python34, python33 and python27 deliver versions 3.4,
3.3 and 2.7 of the Python interpreter, pip installer (except python33,
which does not include pip) and some other modules that are also
included in the collections as RPMs.

For more on the Python, see https://www.python.org/

The SCLo SIG in CentOS
----------------------
The Software Collections SIG group is an open community group
co-ordinating the development of the SCL technology, and helping curate
a reference set of collections. In addition to the Python collections
being released here, we also build and deliver databases, web servers,
and language stacks including multiple versions of PostgreSQL, MariaDB,
Apache HTTP Server, NodeJS, Ruby and others.

Software Collections SIG release was announced at
https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html

You can learn more about Software Collections concepts at:
http://softwarecollections.org
You can find information on the SIG at
https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto
get involved and help with the effort.

We meet every second Wednesday at 16:00 UTC in #centos-devel (ref:
https://www.centos.org/community/calendar), for an informal open forum
open to anyone who might have comments, concerns or wants to get started
with SCL's in CentOS.

Enjoy!

Announcing release for Ruby 1.9.3, 2.0.0, 2.2 and Ruby on Rails 3.2, 4.0, 4.1 on CentOS Linux 6 x86_64 SCL

I am pleased to announce the immediate availability versions 1.9.3,
2.0.0, and 2.2 of the Ruby, and versions 3.2, 4.0 and 4.1 of the Ruby on
Rails, now also on CentOS Linux 6 x86_64, delivered via a Software
Collection (SCL) built by the SCLo Special Interest Group
(https://wiki.centos.org/SpecialInterestGroup/SCLo).

This is an addition for the Ruby collections that are already available
for CentOS 7
(https://lists.centos.org/pipermail/centos-announce/2015-November/021501.html).

QuickStart
----------
You can get started in three easy steps (example of Ruby 2.2 and Ruby on
Rails 4.1):
$ sudo yum install centos-release-scl
$ sudo yum install rh-ruby22 rh-ror41
$ scl enable rh-ruby22 bash

At this point you should be able to use ruby just as a normal
application. An examples of commands run might be:
$ ruby my-app.rb
$ gem install activeresource
$ bundle

In order to view the individual components included in this
collection, including additional rubygems plugins, you can run:
$ sudo yum list rh-ruby22\* rh-ror41\*

The rh-ror41 collection relies on the rh-ruby22 collection and the ror40
collection relies on the ruby200 collection, so the Ruby collections
will be also installed when the Ruby on Rails collection is installed.

About Software Collections
--------------------------
Software Collections give you the power to build, install, and use
multiple versions of software on the same system, without affecting
system-wide installed packages. Each collection is delivered as a group
of RPMs, with the grouping being done using the name of the collection
as a prefix of all packages that are part of the software collection.

The collection rh-ruby22 delivers bundler and version 2.2 of the Ruby
interpreter, while the collection rh-ror41 delivers version 4.1 of the
Ruby on Rails framework that allows to create and run applications in
Ruby or Ruby on Rails framework.

The collection ruby200 delivers version 2.0.0 of the Ruby interpreter,
while the ror40 collection delivers version 4.0 of the Ruby on Rails
framework and bundler.

The collection ruby193 delivers version 1.9.3 of the Ruby interpreter,
bundler and version 3.2 of the Ruby on Rails framework.

Some of the most common rubygems are also included in the collections as
RPMs, the rest may be installed using bundler or gem tools.

http://rubyonrails.org or https://rubygems.org .
