        <h3><a name="TODO">TODO, 2009 - JSCoverage 0.5</a></h3>
        <p>
        JSCoverage 0.5 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
        </p>
        <p>
        This release contains a number of new features and bug fixes:
        </p>
        <ul class="list">
        <li>
        A new mode of operation, called "window mode", allows you to run code in a new browser window (or tab).
        </li>
        <li>
        The method used to calculate overall percentage code coverage for all
        files has changed.  Previously, the calculation was done using an
        unweighted average: each file's percentage code coverage contributed
        equally to the total, regardless of the number of lines of code in the
        file.  Now, the calculation is done using a weighted average.  This
        fixes
        <a href="http://siliconforks.com/jscoverage/bugs/6">bug #6</a> (thanks to
        Liu Cougar).
        </li>
        <li>
        Contiguous lines in the "Missing" column are now grouped together (thanks to
        Liu Cougar).
        </li>
        <li>
        The "Source" tab is no longer empty when code being tested throws an
        uncaught exception
        (fixing <a href="http://siliconforks.com/jscoverage/bugs/5">bug #5</a>)
        </li>
        <li>
        Previously, certain uses of the <code>new</code> operator were
        instrumented incorrectly; this has now been fixed
        (thanks to Guillaume Lung).
        </li>
        <li>
        The <code>jscoverage-server</code> program now allows more characters in
        URLs (thanks to Guillaume Lung).
        </li>
        <li>
        The <code>jscoverage-server</code> program now handles HTTP headers with
        empty values (thanks to Velo).
        </li>
        <li>
        The <code>jscoverage</code> program now refuses to instrument code which
        has already been instrumented (thanks to Velo).
        </li>
        <li>
        URLs containing spaces now work correctly (thanks to Igor Papkov).
        </li>
        <li>
        Previously, on Windows, the <code>jscoverage</code> program
        was unable to instrument a directory in a drive root; this has now been
        fixed.
        </li>
        <li>
        A limitation of 65,535 lines per file and 65,535 characters per line has
        been removed.
        </li>
        <li>
        Floating-point numbers are how handled with improved precision.
        </li>
        <li>
        The <code>jscoverage-server</code> program can no longer bind to the same port multiple times on Windows.
        </li>
        <li>
        Some bugs in <code>jscoverage-server</code>'s handling of the "chunked"
        Transfer-Encoding have been fixed.
        </li>
        <li>
        Compilation under Cygwin now uses the <code>-mno-cygwin</code> flag.
        </li>
        <li>
        The wire format used for submitting coverage reports for storage by
        <code>jscoverage-server</code> has changed.  (This change will not have
        any visible effects for most users; it will only be of interest to those
        who have written code which parses that format.)
        </li>
        </ul>

        <h3><a name="20081211">December 11, 2008 - JSCoverage 0.4</a></h3>
        <p>
        JSCoverage 0.4 is available for <a href="http://siliconforks.com/jscoverage/download.html">download</a>.
        </p>
        <p>
        This release includes many new features:
        </p>
        <ul class="list">
        <li>
        The new <code>jscoverage-server</code> program is provided as an
        alternative to the <code>jscoverage</code> program.  The
        <code>jscoverage-server</code> program is a simple HTTP server which
        instruments JavaScript code as it is served; this allows you to execute
        JavaScript and gather code coverage statistics without a preliminary
        step of creating instrumented code. The <code>jscoverage-server</code>
        program can either serve files directly from the filesystem or run as a
        proxy server (with the <code>--proxy</code> option), instrumenting
        JavaScript provided by another web server.
        <li>
        Using <code>jscoverage-server</code>, coverage reports can now be stored
        to the filesystem.
        </li>
        <li>
        JSCoverage now recognizes special JavaScript comments which specify that
        certain lines of code should be ignored in coverage reports.
        </li>
        <li>
        The new <code>--encoding</code> option provides better support for
        different character encodings.
        </li>
        <li>
        The JSCoverage user interface is now faster and more responsive.
        </li>
        <li>
        The new <code>--no-highlight</code> option can be used to disable syntax
        highlighting (giving better performance for large JavaScript files).
        </li>
        <li>
        The build system has been modified so that <code>make install</code>
        only installs the <code>jscoverage</code> and
        <code>jscoverage-server</code> executables and their manual pages.
        (Previous versions installed SpiderMonkey library and executable files,
        which could conflict with other versions of SpiderMonkey installed on
        your system.)
        </li>
        <li>
        JSCoverage now supports several features beyond those found in the
        <cite>ECMAScript Language Specification</cite>, including the following:
        <ul class="list">
        <li>getters and setters
        <li><code>for each</code> loops
        <li>generators and iterators
        <li>the <code>let</code> keyword
        <li>destructuring assignment
        <li>array comprehensions
        <li>expression closures
        <li>generator expressions
        </ul>
        Use the new <code>--js-version</code> option to enable these features.
        </li>
        </ul>
        <p>
        The GCC C++ compiler (<code>g++</code>) is now required to compile
        JSCoverage.  (Previously, only the C compiler was needed.)
