Git has been updated to 2.4.0 from 2.1.0 [https://bugzilla.redhat.com/show_bug.cgi?id=1217767 Ticket for Documentation of Git 2.4.0]
Fedora 22 has includes Git 2.4.0. Git is a very popular version control and collaboration tool. The
previous version of Git was 2.1.0 in Fedora 21.
 
 
== New Features: ==


== Boost ==


{{package|boost}} provides a set of portable, peer-reviewed, C++ libraries.  In Fedora 15, Boost is brought up to date with the current upstream, version 1.4.6.
'''git push --atomic'''


With every new release of Boost come new components and libraries. For instance, Boost 1.46 brings ICL, and Boost 1.45 had already brought MSM and Polygon.
New to Git in 2.4 and for Fedora is the ''atomic'' option. The '''--atomic''' option does an all - or - nothing
push update. This can be useful for automated tools. An example would be adding '''--atomic''' to the end
of a simple git push: '''git push origin --atomic''' For more information on how to do an atomic
push please visit [https://github.com/blog/1994-git-2-4-atomic-pushes-push-to-deploy-and-more https://github.com/blog/1994-git-2-4-atomic-pushes-push-to-deploy-and-more].


Moreover, the existing components and libraries are enhanced with new features and bug fixes. For instance, the Boost.Math components have now become better than the GSL for support to statistical analysis.
'''Push to Deploy'''


For full details, see the Boost pages at http://www.boost.org/
Introduced in Git 2.3.0 and new to Fedora is the ability to push to deploy. This feature will allow
someone to push a branch to a git server even if the branch is checked out on that server.


== gdb ==
'''Inverted Grep'''


Fedora 15 features GDB release 7.3. This, together with [http://sourceware.org/gdb/wiki/ArcherBranchManagement Archer] and Fedora extensions improves debugging experience on Fedora by making the debugger more powerful.  The majority of these features were written by Red Hat engineers, thus benefiting all gdb users.   New features for the Fedora 15 release are not limited to:
''Inverted grep'', or ''--inverted grep'' will let you search for items that do not match the pattern you
* Support for breakpoints at [http://sourceware.org/systemtap/wiki/AddingUserSpaceProbingToAppsSystemtap SystemTap markers (probes)]
have entered. Inverted grep will give the ability to do "everything else but" searching. For example,
* Support for using labels in the program's source
if you wanted to search the git log for everything the user ''grundblom'' did that ''was not grammer'' edits
* OpenCL language debugging support
You could use the command: '''git log --all --author=grundblom --invert-grep --grep=grammer'''
* Thread debugging of core dumps - priting <code>pthread_t</code> of threads and their TLS variables
* Python scripting improvements not limited to:
** GDB values in Python are now callable if the value represents a function address.
** New module gdb.types for inferior types.
** New module gdb.printing for writing and registering pretty-printers.
More features are listed [http://sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/src/gdb/NEWS?cvsroot=src upstream] above the line <code>*** Changes in GDB 7.2</code>.


Numerous important packages within Fedora are pre-built with [[Features/SystemtapStaticProbes|SystemTap static markers]], and these can now be used as the target for breakpoints in gdb.
