<ul class="simple">
<li>Wildcard matching has been expanded. All previous wildcard
expressions are still valid; some will match strictly more files
than before. Specifically:<ul>
<li>Double-star (<code class="docutils literal"><span class="pre">**</span></code>) wildcards are now accepted for recursive
matching immediately before the final slash; they must be followed
by a filename wildcard (e.g., <code class="docutils literal"><span class="pre">foo/**/*.html</span></code> is valid;
<code class="docutils literal"><span class="pre">foo/**/bar/*.html</span></code> and <code class="docutils literal"><span class="pre">foo/**/**/*.html</span></code>,
<code class="docutils literal"><span class="pre">foo/**/bar.html</span></code> are all invalid). As <code class="docutils literal"><span class="pre">**</span></code> was an error in
globs before, this does not affect any existing <code class="docutils literal"><span class="pre">.cabal</span></code> files
that previously worked.</li>
<li>Wildcards now match when the pattern’s extensions form a suffix of
the candidate file’s extension, rather than requiring strict
equality (e.g., previously <code class="docutils literal"><span class="pre">*.html</span></code> did not match
<code class="docutils literal"><span class="pre">foo.en.html</span></code>, but now it does).</li>
</ul>
</li>
<li>License fields use identifiers from SPDX License List version
<code class="docutils literal"><span class="pre">3.2</span> <span class="pre">2018-07-10</span></code></li>
