<ul>
<li>Greatly improved documentation, especially around platform-specific behaviours;</li>
<li>Improved test suite by building our own library to test against;</li>
<li>All <code>Library</code>-ies now implement <code>Send</code>.</li>
<li>Added <code>impl From&lt;os::platform::Library&gt; for Library</code> and <code>impl From&lt;Library&gt; for os::platform::Library</code> allowing wrapping and extracting the platform-specific library handle;</li>
<li>Added methods to wrap (<code>Symbol::from_raw</code>) and unwrap (<code>Symbol::into_raw</code>) the safe <code>Symbol</code>
wrapper into unsafe <code>os::platform::Symbol</code>.</li>
</ul>
<p>The last two additions focus on not restricting potential usecases of this library, allowing
users of the library to circumvent safety checks if need be.</p>
<h2 id="breaking-changes" class="section-header"><a href="#breaking-changes">Breaking Changes</a></h2>
<p><code>Library::new</code> defaults to <code>RTLD_NOW</code> instead of <code>RTLD_LAZY</code> on UNIX for more consistent
cross-platform behaviour. If a library loaded with <code>Library::new</code> had any linking errors, but
unresolved references weren’t forced to be resolved, the library would’ve “just worked”,
whereas now the call to <code>Library::new</code> will return an error signifying presence of such error.</p>
<h2 id="osplatform" class="section-header"><a href="#osplatform">os::platform</a></h2>
<ul>
<li>Added <code>os::unix::Library::open</code> which allows specifying arbitrary flags (e.g. <code>RTLD_LAZY</code>);</li>
<li>Added <code>os::windows::Library::get_ordinal</code> which allows finding a function or variable by its
ordinal number;</li>
</ul>

</ul>
<h2 id="thread-safety" class="section-header"><a href="#thread-safety">Thread-safety</a></h2>
<p>The implementation strives to be as MT-safe as sanely possible, however due to certain
error-handling related resources not always being safe, this library is not MT-safe either.</p>
<ul>
<li>On Windows Vista and earlier error handling falls back to <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/ms680621(v=vs.85).aspx"><code>SetErrorMode</code></a>, which is not
MT-safe. MT-scenarios involving this function may cause a traditional data race;</li>
<li>On some UNIX targets <code>dlerror</code> might not be MT-safe, resulting in garbage error messages
in certain MT-scenarios.</li>
</ul>
<p>Calling this function from multiple threads is not safe if used in conjunction with
path-less filename and library search path is modified (<code>SetDllDirectory</code> function on
Windows, <code>{DY,}LD_LIBRARY_PATH</code> environment variable on UNIX).</p>
<h2 id="platform-specific-behaviour" class="section-header"><a href="#platform-specific-behaviour">Platform-specific behaviour</a></h2>
<p>When a plain library filename is supplied, locations where library is searched for is
platform specific and cannot be adjusted in a portable manner.</p>
<h3 id="windows" class="section-header"><a href="#windows">Windows</a></h3>
<p>If the <code>filename</code> specifies a library filename without path and with extension omitted,
<code>.dll</code> extension is implicitly added. This behaviour may be suppressed by appending a
trailing <code>.</code> to the <code>filename</code>.</p>
<p>If the library contains thread local variables (MSVC’s <code>_declspec(thread)</code>, Rust’s
<code>#[thread_local]</code> attributes), loading the library will fail on versions prior to Windows
Vista.</p>
<h2 id="tips" class="section-header"><a href="#tips">Tips</a></h2>
<p>Distributing your dynamic libraries under a filename common to all platforms (e.g.
<code>awesome.module</code>) allows to avoid code which has to account for platform’s conventional
library filenames.</p>
<p>Strive to specify absolute or relative path to your library, unless system-wide libraries
are being loaded. Platform-dependent library search locations combined with various quirks
related to path-less filenames may cause flaky code.</p>
