<h1>Jython 2.7rc2 Release Notes</h1>
<div class="section" id="id1">
<h2>Bugs fixed</h2>
<blockquote>
<ul class="simple">
<li>[ 2301 ] time.strftime now always returns a bytestring (fixes pip on Japanese locales)</li>
<li>[ 2297 ] Updates Jython installer to use jython.exe</li>

</div>
<div class="section" id="new-features">
<h2>New features</h2>
<blockquote>
<ul class="simple">
<li>Installer installs pip, setuptools by default, but custom builds can de-select.
Does not change standalone usage. (Runs jython -m ensurepip as last install step.)</li>
<li>Makes jython.py be the default launcher (as bin/jython) if CPython 2.7 is available.</li>
</ul>
</blockquote>
</div>
<div class="section" id="removed-support">
<h2>Removed support</h2>
<blockquote>
<ul class="simple">
<li>Installer no longer supports using an alternative JRE when generating Jython launchers.
Instead just use JAVA_HOME environment variable to select the desired JRE.
(Removed because of the new native launcher, jython.exe, that is now used on Windows.)</li>
</ul>

<h2>New features</h2>
<blockquote>
<ul class="simple">
<li>Can add a __dict__ slot descriptor to a subclass of Java classes, such as java.util.HashMap</li>
<li>Directly execute zip files or dirs with top level __main__.py to support wrapper scripts
generated by distlib, part of pip</li>
<li>Reflection-based traversal is now activated by default as a fallback for ordinary traversal.
This impacts third-party extenders of PyObject. A warning is emitted that suggests next steps
on how to avoid this cost.</li>
<li>Uses classpath wildcard in jython.py/jython.exe to minimize the launcher command line,
(main benefit is Jython developers on Windows using dev builds)</li>
<li>Adds new Jython launcher written in Python, bin/jython.py, to be run by CPython 2.7</li>

<div class="section" id="potentially-backwards-breaking-changes-removing-silent-errors">
<h2>Potentially backwards breaking changes, removing silent errors</h2>
<blockquote>
<ul class="simple">
<li>remove method on proxied List objects now follows Python
sematics: a ValueError is raised if the item is not found in the
java.util.List. In the past, Java semantics were used, with a
boolean returned indicating if the item was removed or
not. Given how this interacted with Jython, such remove
invocations were in the past silent, and perhaps were actually a
bug.</li>
<li>d[key_not_present], if d implement java.util.Map, no longer
returns None, but raises KeyError, which means this behavior now
matches standard dict semantics.</li>
<li>Abstract methods of an inherited class or interface from Java now raise
NotImplementedError, instead of returning None (in Java, null) or some
"zero", if they are not implemented in the extending Python class.</li>
<li>os.getenv, os.listdir, sys.argv now return unicode instead of
str values if a given value is not ascii, thus allowing such
values to be passed through to Java, eg
java.io.File(sys.argv[1]). Earlier such behavior was potentially
silently failing in Python functions, but passing through to
Java because of bug 2037. This behavior conforms with Python
3.x, which uses Unicode.</li>
