<h2>Summary of Changes in version 4.10 [unreleased!]</h2>

<p>A full summary of commits between 4.9 and 4.10 is on <a href="https://github.com/junit-team/junit/compare/r4.9...4.10">github</a></p>

<h3>junit-dep has correct contents</h3>

<p>junit-dep-4.9.jar incorrectly contained hamcrest classes, which could lead to version conflicts in projects that depend on hamcrest directly.  This is fixed in 4.10 [@dsaff, closing gh-309]</p>

<h3>RuleChain</h3>

<p>The RuleChain rule allows ordering of TestRules:</p>

<pre><code>public static class UseRuleChain {
    @Rule
    public TestRule chain= RuleChain
                           .outerRule(new LoggingRule("outer rule")
                           .around(new LoggingRule("middle rule")
                           .around(new LoggingRule("inner rule");

    @Test
    public void example() {
        assertTrue(true);
    }
}
</code></pre>

<p>writes the log</p>

<pre><code>starting outer rule
starting middle rule
starting inner rule
finished inner rule
finished middle rule
finished outer rule
</code></pre>

<h3>TemporaryFolder</h3>

<ul>
<li><code>TemporaryFolder#newFolder(String... folderNames)</code> creates recursively deep temporary folders 
[@rodolfoliviero, closing gh-283]</li>
<li><code>TemporaryFolder#newFile()</code> creates a randomly named new file, and <code>#newFolder()</code> creates a randomly named new folder
[@Daniel Rothmaler, closing gh-299]</li>
</ul>

<h3>Theories</h3>

<p>The <code>Theories</code> runner does not anticipate theory parameters that have generic
types, as reported by github#64.  Fixing this won't happen until <code>Theories</code> is
moved to junit-contrib. In anticipation of this, 4.9.1 adds some of the
necessary machinery to the runner classes, and deprecates a method that only
the <code>Theories</code> runner uses, <code>FrameworkMethod</code>#producesType(). 
The Common Public License that JUnit is released under is now included
in the source repository.</p>

<p>Thanks to <code>@pholser</code> for identifying a potential resolution for github#64
and initiating work on it.</p>
