<blockquote>
<h2>[0.5.0] - 2021-06-11</h2>
<h3>Added</h3>
<ul>
<li><code>open_browser()</code>, which uses the <code>$BROWSER</code> environment variable before falling back to <code>open()</code>.</li>
<li>WSL-specific implementation. Previously, WSL used the same implementation as Linux. Now the strategy on WSL is to use
the system's <code>wslview</code> command from <a href="https://github.com/wslutilities/wslu"><code>wslu</code></a> if available, falling back to the
system <code>xdg-open</code>, if available.</li>
</ul>
<h3>Changed</h3>
<ul>
<li>On Linux (non-WSL), the system <code>xdg-open</code> is now used if present. Otherwise, the bundled version is used, as before.</li>
<li>Avoid blocking the thread on Linux and WSL.</li>
</ul>
<h3>Removed</h3>
<ul>
<li><code>impl From&lt;io::Error&gt; for OpenError</code>.</li>
</ul>
<h2>[0.4.1] - 2019-09-30</h2>
<h3>Changed</h3>
<ul>
<li>Update <code>xdg-open</code>.</li>
</ul>
<h2>[0.4.0] - 2019-05-02</h2>
<h3>Added</h3>
<ul>
<li><code>OpenError</code> now implements <code>std::error::Error</code>.</li>
</ul>
<h3>Changed</h3>
<ul>
<li><code>OpenError</code>'s <code>failure::Fail</code> impl was removed from this crate, but the failure crate provides a blanket impl of
<code>failure::Fail</code> for types implementing <code>std::error::Error</code>, so this shouldn't break anything.</li>
</ul>
<h2>[0.3.0] - 2018-08-18</h2>
<h3>Added</h3>
<ul>
<li><code>stderr</code> field to <code>OpenError::ExitStatus</code> variant, which captures anything the failed process wrote to stderr.</li>
</ul>
<h2>[0.2.0] - 2018-08-08</h2>
<h3>Removed</h3>
<ul>
<li>The <code>open_sys</code> function, which was erroneously pub on non-Windows builds.</li>
</ul>
<h2>[0.1.0] - 2018-08-08</h2>
<ul>
<li>Initial release.</li>
</ul>
