==New Programming Language==
{{Docs_beat_closed}}
Fedora 14 introduces support for '''D'''[http://www.digitalmars.com/d/], a systems programming language combining the power and high performance of C and C++ with the programmer productivity of modern languages such as Ruby and Python.


==Support for GNUStep==
== Perl 5.24 ==
The GNUstep development environment arrives on Fedora, allowing easy development of cross-platform applications on Fedora using the Cocoa (formerly NeXTSTEP/OpenStep) APIs and tools. GNUstep's main development language is Objective-C, but GNUstep is not limited to that.
Perl has been updated to the latest stable version, 5.24, for Fedora 25. Changes include:


==Other improvements==
{{:Changes/perl5.24}}
* Updates to the '''Python''', '''Erlang''' and '''Perl''' languages and the '''Netbeans''' and '''Eclipse''' development environments.
* The '''gdb''' debugger has been extended with new commands that make it easier to track down and fix excessive memory usage within programs and libraries, as well as an index that greatly speeds up debugging.  


These features complete a rich set of development tools that further extends the possibilities for developers. For a complete list of the hundreds of updated development components see the Fedora 14 Technical Notes at http://docs.fedoraproject.org.
== Node.js 6.x ==
Fedora 25 offers Node.js 6.x, the latest LTS release of the platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.  


This replaces the older Node.js 4.x libraries found in legacy Fedora releases.  Users of Node.js applications should notice no problems from this change, although developers should review the upstream release notes and API changes:

Beat Closed on Wiki
Work on beats has now moved to git at https://pagure.io/fedora-docs/release-notes. If you have changes or additions, please contact the docs team via #fedora-docs, docs@lists.fedoraproject.org, or with the release-notes BZ component.


Perl 5.24

Perl has been updated to the latest stable version, 5.24, for Fedora 25. Changes include:


  • New features:
    • Unicode 8.0 is now supported.
    • An exception will be raised when closing an in-place output file fails.
    • (?[ ]) will successfully compile when use locale is in effect.
    • Integer shift (<< and >>) now more explicitly defined. Negative shifts are reverse shifts.
    • printf and sprintf now allow reordered precision arguments.
    • When passing the SA_SIGINFO flag to sigaction, the errno, status, uid, pid, addr and band fields are included in the hash passed to the handler, if supported by the platform.
    • Hashbang redirection was extended also to Perl 6.
  • Changes:
    • Postfix dereferencing is no longer experimental.
    • Remove duplicate environment variables from environ.
    • More regular expression patterns are now checked for validity at compilation time, and invalid ones will cause the program to not compile.
    • Using \N{} is a fatal error under experimental feature "'strict' mode" in re.
    • A my, our, or state declaration is no longer allowed inside of another my, our, or state declaration.
    • The /\C/ character class has been removed.
    • Using chdir(\'\') or chdir(undef) to change working directory to a home directory fails now. Use chdir() instead.
    • ASCII characters in variable names must now be all visible.
    • $Carp::MaxArgNums is supposed to be the number of arguments to display.
    • Only blanks and tabs are now allowed within [...] within (?[...]).
    • Matching fixed string regular expression is now faster in most cases.
  • Removed features:
    • The autoderef feature has been removed.
    • Lexical $_ has been removed.
    • PPPort.so no longer get installed, as they are not used by PPPort.pm.
    • Using code points above the platform's IV_MAX is now deprecated.
    • Bitwise operations on strings containing code points above 0xFF is deprecated. Instead, encode these strings to byte strings first.
    • sysread(), syswrite(), recv() and send() are deprecated on :utf8 handles.


Node.js 6.x

Fedora 25 offers Node.js 6.x, the latest LTS release of the platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

This replaces the older Node.js 4.x libraries found in legacy Fedora releases. Users of Node.js applications should notice no problems from this change, although developers should review the upstream release notes and API changes:
