<a href="/pkg/os/#Executable"><code>Executable</code></a> returns
the path name of the running executable.
</p>
<p> <!-- CL 30614 -->
An attempt to call a method on
an <a href="/pkg/os/#File"><code>os.File</code></a> that has
already been closed will now return the new error
value <a href="/pkg/os/#ErrClosed"><code>os.ErrClosed</code></a>.
Previously it returned a system-specific error such
as <code>syscall.EBADF</code>.
</p>
<p> <!-- CL 31358 -->
On Unix systems, <a href="/pkg/os/#Rename"><code>os.Rename</code></a>
will now return an error when used to rename a directory to an
existing empty directory.
Previously it would fail when renaming to a non-empty directory
but succeed when renaming to an empty directory.
This makes the behavior on Unix correspond to that on other systems.
</p>
<p> <!-- CL 32451 -->
On Windows, long absolute paths are now transparently converted to
extended-length paths (paths that start with <code>\\?\</code>).
This permits the package to work with files whose path names are
longer than 260 characters.
</p>
<p> <!-- CL 29753 -->
On Windows, <a href="/pkg/os/#IsExist"><code>os.IsExist</code></a>
will now return <code>true</code> for the system
error <code>ERROR_DIR_NOT_EMPTY</code>.
This roughly corresponds to the existing handling of the Unix
error <code>ENOTEMPTY</code>.
</p>
<p> <!-- CL 32152 -->
On Plan 9, files that are not served by <code>#M</code> will now
have <a href="/pkg/os/#ModeDevice"><code>ModeDevice</code></a> set in
the value returned
by <a href="/pkg/os/#FileInfo"><code>FileInfo.Mode</code></a>.

<p> <!-- CL 32796 -->
In a Go library built with <code>-buildmode=c-archive</code>
or <code>c-shared</code>, when C code calls a Go function,
the <code>SIGPIPE</code> signal will be treated as usual for Go code.
In particular, when <code>SIGPIPE</code> is triggered by a write
to a closed Go network connection, it will not cause the program
to exit.
