<h2>1.59.0</h2>
<ul>
<li>Update the Tutorial:<ul>
<li>Use C++11 in the example programs to improve clarity.</li>
<li>Update the example source code show to match the actual example source
code in the cpp files.</li>
<li>Rerun all the examples and update the output shown in the tutorial
accordingly.</li>
<li>Fix spacing and other HTML presentation issues.</li>
</ul>
</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/11491">#11491</a>,
<code>temp_directory_path()</code> doesn't return valid temp path on Android.</li>
</ul>
<h2>1.58.0</h2>
<ul>
<li>Rewrite Windows implementation of temp_directory_path() to (1) avoid
GetTempPath() failure if path length > 130 (ticket #5300) and (2) provide a
more sensible sequence of directories than provided by GetTempPath(), per
boost list discussion "[filesystem] temp_directory_path() behavior on
Windows". The new sequence is:<ol>
<li><i><code>%TMP%</code></i></li>
<li><i><code>%TEMP%</code></i></li>
<li><code><i>%LOCALAPPDATA%</i>/Temp</code></li>
<li><code><i>%USERPROFILE%</i>/Temp</code></li>
<li><code><i>GetWindowsDirectoryW()</i>/Temp</code></li>
</ol>
</li>
</ul>
<h2>1.57.0</h2>
<ul>
<li>Rework class <code>path</code> locale and codecvt implementation for increased reliability.
This change was SVN revision 83021, which should have gone into 1.56.0 but
unfortunately the merge didn't happen until too late.</li>
<li>Fix tickets <a href="https://svn.boost.org/trac/boost/ticket/8930">#8930</a>, <a href="https://svn.boost.org/trac/boost/ticket/9054">#9054</a>,
<a href="https://svn.boost.org/trac/boost/ticket/9214">#9219</a>,
<a href="https://svn.boost.org/trac/boost/ticket/10228">#10228</a>, and
<a href="https://svn.boost.org/trac/boost/ticket/10641">#10641</a>, all
related to locales and codecvt facets.</li>
<li>The net effect of the above changes and fixes should be to eliminate
spurious "locale::facet::_S_create_c_locale name not valid" errors on Linux
and other non-BSD POSIX-like systems. The error will continue to occur, as it
should, when a path encoding conversion char-to-wchar_t or wchar_t-to-char is
attempted in an environment without a valid C locale (for example, if the LANG
environment variable is invalid or not defined).</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/6124">#6124</a>,
<a href="https://svn.boost.org/trac/boost/ticket/6779">#6779</a>, and
<a href="https://svn.boost.org/trac/boost/ticket/10038">#10038</a> - an
undefined reference that occurred when the library was compiled for C++03 but
the using program was compiled for C++11, or vice versa. The private library
interface has been changed to use a plain-old C++03 enum. This is the fix
suggested by Andy in 6779.</li>
<li>The Windows implementation now treats NTFS directory junctions (also known
as junctions, also known as mount points) as symlinks. This has the effect of
treating directory junctions as directories, and thus supporting all
operations suitable for directories. This resolves
<a href="https://svn.boost.org/trac/boost/ticket/9016">#9016</a>. Directory
junctions are very similar to symlinks, but may have performance or other
advantages in some situations. They can be created from the command line with
"<code>mklink /j link target</code>". There is no plan for Boost.Filesystem to
be able to create them directly other than by calling <code>std::system()</code>.</li>
</ul>
<h2>1.56.0</h2>
<ul>
<li>Reorganize <code>recursive_directory_iterator::increment</code>, adding an
invariant that progress is always made, even if an error is reported by
exception or error_code. Add a manually executed test, <code>
test/issues/recurse_dir_iter_5403.cpp</code>. Adjust regular regression tests
as needed. Thanks to Claudio Bley for the
<a href="https://github.com/boostorg/filesystem/pull/4">pull request</a> - the
change was incorporated into the reorganized code. Fixes
<a href="https://svn.boost.org/trac/boost/ticket/5403">#5403</a> and
<a href="https://svn.boost.org/trac/boost/ticket/6821">#6821</a>.</li>
<li>Fix <code>canonical()</code> to treat parent of root as root. (Christian
Hammerl) Fixes <a href="https://svn.boost.org/trac/boost/ticket/9683">#9683</a>
and <a href="https://svn.boost.org/trac/boost/ticket/10187">#10187</a>.</li>
<li>Added missing test for <code>__sun</code> macro which is defined on
Solaris 10. (Chris Stylianou)</li>
<li>Minor fixes and code cleanup.</li>
<li>Update IDE projects to Visual Studio 2013.</li>
<li>Remove unused <code>const char colon</code> to clear clang warning. (J?gen
Hunold)</li>
<li>Add BOOST_NOEXCEPT to <code>class filesystem_error</code>.</li>
<li>Change <code>perms::all_all</code> and <code>perms::perms_mask</code> to
absolute values to quiet intellisense warnings, and conform to C++11.</li>
</ul>
<h2>1.54.0</h2>
<ul>
<li>Reimplement <code>path::codecvt()</code> and <code>path::imbue()</code>
with portable code that is intended to be much more robust and maintainable. A
section on <a href="reference.html#path-Usage">path usage concerns</a> has
been added to the reference documentation describing several concerns that
arise in the context of multithreading and <code>path::codecvt()</code>.</li>
</ul>
<h2>1.52.0</h2>
<ul>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/7239">#7239</a>, Stack
overflow when calling <code>create_directories(":D")</code>. The reported
problem was a symptom of an internal bug that caused <code>path::filename()</code>
and <code>path::parent_path()</code> to fail on Windows for <code>path(":")</code>,
and that in turn caused other functions that depend on <code>filename()</code>
or <code>parent_path()</code> to fail, such as <code>create_directories()</code>.</li>
</ul>
<h2>1.51.0</h2>
<ul>
<li>Add begin() and end() non-member functions for directory_iterator and
recursive_directory_iterator so that C++11 range-based for statements work.
Suggested by feature requests
<a href="https://svn.boost.org/trac/boost/ticket/5896">#5896</a> and
<a href="https://svn.boost.org/trac/boost/ticket/6521">#6521</a>, using the
<a href="https://svn.boost.org/trac/boost/ticket/5896">#5896</a> approach.</li>
<li>Add range_begin() and range_end() non-member functions for directory_iterator and
recursive_directory_iterator so that
<a href="http://www.boost.org/libs/foreach/">BOOST_FOREACH</a> works.</li>
<li>Fix a Linux fchmodat problem affecting symlink permissions reported during
discussion of <a href="https://svn.boost.org/trac/boost/ticket/6659">#6659</a>.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/6659">#6659</a> and
<a href="https://svn.boost.org/trac/boost/ticket/7051">#7051</a>, fchmodat
supported only on Solaris 11. Fix for both Sun and GCC compilers. </li>
</ul>
<h2>1.50.0</h2>
<ul>
<li>Remove Filesystem Version 2 from the distribution. Version 3 is now the
only distributed version. Those still using V2 are urged to migrate to V3 as
soon as possible.</li>
<li>Add <code>constexpr value_type preferred_separator</code> to class path.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5118">#5118</a>,
<code>replace_extension</code> doesn't work as specified in documentation. The
documentation, implementation, and test cases have all had fixes applied. The
documentation had failed to mention that any existing extension is removed.
The behavior for simple cases has been reverted to the Version 2 behavior, but
with corrections so that complex replacements now work. Two test cases from
#5118 have been added.</li>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/3737">#3737</a>,
Boost.Filesystem does not compile on Windows Mobile. On Windows, <sys/stat.h>
is no longer included.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/4065">#4065</a>,
Boost Filesystem lexicographic path comparison inconsistent. This required
multiple source code bug fixes and code cleanup, correcting problems not
related to lexicographical issues.</li>
<li>Add class path member function <code>compare</code> for consistency with
std::string.</li>
<li>Tighten BOOST_FILESYSTEM_DYN_LINK and BOOST_FILESYSTEM_STATIC_LINK logic
in filesystem/config.hpp so that one or the other is always defined, and both
being defined is a #error.</li>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/6690">#6690</a> and
<a href="http://svn.boost.org/trac/boost/ticket/6737">#6737</a>, resolving
static linking related problems with VC++ 8 through 11. Note that this fix may
reintroduce codecvt thread safety problems
<a href="http://svn.boost.org/trac/boost/ticket/4889">#4889</a>,
<a href="http://svn.boost.org/trac/boost/ticket/6320">#6320</a>, for these
compilers if static linking is used.</li>
<li>Add path::operator+= and concat functions to tack on things like suffixes
or numbers. Suggested by Ed Smith-Rowland and others.</li>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/6809">#6809</a>,
Implementation of filesystem::rename() method for MS Windows is wrong, by
adding MOVEFILE_COPY_ALLOWED to deal with renames across drives, volumes, file
systems. Fix has no effect on non-Windows systems.</li>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/6819">#6819</a>, A path operand with a source that was a one character array was
treated as empty, even if it wasn't empty. Such arrays can occur in unions or
in code using C variable length array idioms.</li>
<li>Fix <a href="http://svn.boost.org/trac/boost/ticket/6932">#6932</a>,
create_directories throws exception even if error_code is specified.</li>
</ul>
<h2>1.49.0</h2>
<ul>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/3714">#3714</a>,
Added test cases and fixes for class path errors when assignment or append
used self or portion of self as source. </li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/4889">#4889</a>,
<a href="https://svn.boost.org/trac/boost/ticket/6320">#6320</a>, Locale codecvt_facet not thread safe on Windows. Move
Windows, Mac OS X, locale and codecvt facet back to namespace scope. POSIX
except OS X uses local static initialization (IE lazy) to ensure exceptions
are catchable if environmental variables are misconfigured and to avoid use of
locale("") if not actually used.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5652">#5652</a>,
recursive_directory_iterator fails on cyclic symbolic links. Thanks to Daniel
Aarno for the patch.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5653">#5653</a>,
recursive_directory_iterator(error_code) can still throw filesystem_error.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5900">#5900</a>, directory_iterator
access violation on Windows if error is thrown. Thanks to Andreas Eckleder for the patch.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5900#comment:2">#5900
comment 2</a>, a bug in director_iterator construction with error_code argument that
caused increment to be called without the ec argument being passed.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5900">#5989</a> by cleaning up test suite path_test.cpp code even
though the ticket itself was not a defect, and clarifying docs; iteration over a path yields
generic format.</li>
<li>Fix <a href="https://svn.boost.org/trac/boost/ticket/5592">#5592</a>, Change Windows codecvt processing from CP_THREAD_ACP to CP_ACP.</li>
<li>Operations function fixes for PGI compiler, thanks to Noel Belcourt.</li>
<li>Relax permissions test to reflect reality, particularly on the Sandia test
platforms.</li>
</ul>
<h2>1.48.0</h2>
<ul>
<li>Added operational function <a href="reference.html#canonical">canonical()</a>,
suggested by David Svoboda, who also provided pseudo-code.</li>
<li>Added <a href="reference.html#hash_value">hash_value()</a> function for
paths. (Daniel James)</li>
<li>Fix path inserter problem (<a href="https://svn.boost.org/trac/boost/ticket/5764">#5764</a>)
reported for QNX6.3.2 host (gcc-3.3.5)</li>
<li>Fix problem of locale("") exception being thrown before main() starts on
poorly configured (e.g. LANG="bad name") POSIX systems. Resolves the most
serious aspect of tickets
<a href="https://svn.boost.org/trac/boost/ticket/4688">#4688</a>,
<a href="https://svn.boost.org/trac/boost/ticket/5100">#5100</a>,
<a href="https://svn.boost.org/trac/boost/ticket/5289">#5289</a>.</li>
</ul>
<h2>1.47.0</h2>
<ul>
<li>Program file_status.cpp added (V3). See boost-root/libs/filesystem/v3/example.
Useful both as an example and to explore how Boost.Filesystem treats various
status errors. Run "bjam" (NOT "bjam install") in the example directory
to install in example/bin.</li>
</ul>
<h2>1.46.1</h2>
<ul>
<li>Fix fstream problem for STLPort masquerading as Dinkumware (<a href="https://svn.boost.org/trac/boost/ticket/5217">#5217</a>).</li>
</ul>
<h2>1.46.0</h2>
<ul>
<li>Version 3 of the library is now the default.</li>
<li>IBM vacpp: Workaround for compiler bug affecting iterator_facade. (<a href="https://svn.boost.org/trac/boost/ticket/4912">#4912</a>)</li>
<li>Verify, clarify, document that <boost/config/user.hpp> can be used to
specify BOOST_FILESYSTEM_VERSION. (<a href="https://svn.boost.org/trac/boost/ticket/4891">#4891</a>)</li>
<li>Replaced C-style assert with BOOST_ASSERT.</li>
<li>Undeprecated unique_path(). Instead, add a note mentioning the workaround
for lack of thread safety and possible change to cwd. unique_path() is just
too convenient to deprecate!</li>
<li>Cleared several GCC warnings.</li>
<li>Changed V2 code to use BOOST_THROW_EXCEPTION.</li>
<li>Windows: Fix status() to report non-symlink reparse point correctly.</li>
<li>Add <code>symlink_option</code> to <code>recursive_directory_iterator</code>,
allowing control over recursion into directory symlinks. Note that the default
is changed to not recurse into directory symlinks.</li>
<li><a href="reference.html">Reference</a> documentation cleanup, including
fixing missing and broken links, and adding missing functions.</li>
<li>Miscellaneous implementation code cleanup. </li>
</ul>
