{{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.

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.
previous version of Git was 2.1.0 in Fedora 21.


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.

== New Features: ==


== gdb ==


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:
'''git push --atomic'''
* Support for breakpoints at [http://sourceware.org/systemtap/wiki/AddingUserSpaceProbingToAppsSystemtap SystemTap markers (probes)]
* Support for using labels in the program's source
* OpenCL language debugging support
* 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.
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].


== OCaml ==
'''Push to Deploy'''


Fedora 15 includes OCaml 3.12, a major new release of the OCaml language and compiler.  
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.


New language features include:
'''Inverted Grep'''


* modules are now first-class values
''Inverted grep'', or ''--inverted grep'' will let you search for items that do not match the pattern you
* nested module open
have entered. Inverted grep will give the ability to do "everything else but" searching. For example,
* open record notation
if you wanted to search the git log for everything the user ''grundblom'' did that ''was not grammer'' edits
* mark OO methods which must be overridden in subclasses
You could use the command: '''git log --all --author=grundblom --invert-grep --grep=grammer'''
* limited support for [http://pa-do.forge.ocamlcore.org/ delimited overloading] in the language
