+ <title>Python Upgrade to 3.5</title>
+ <para>
+ <application>Python 3.5</application> will be the default Python 3
stack in Fedora 24. This is an upgrade from 3.4 which was included in Fedora 23. All
packages which depend on Python 3 must be rebuilt. User-written Python 3 scripts and
applications may require a small amount of porting; however, Python 3.4 is forward
compatible with Python 3.5 for the most part.

+ <title>Ruby 2.3</title>
+ <para>
+ <application>Ruby 2.3</application> 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 2.2 in Fedora 22 to Ruby 2.3

superior Ruby development platform.

should be rebuilt. Nevertheless, since upstream paid great attention to source
compatibility, no changes to your code are needed.

+ A Frozen String Literal Pragma is introduced. With Ruby 2.1,
<literal>"str".freeze</literal> has been optimized to reduce object
allocation. Ruby 2.3 introduces a new magic comment and command line option to freeze all
string literals in the source files. Additionally for debugging, you can get where the
object is created on <literal>can't modify frozen String</literal> error
