            <p>The coverage analysis tool <c>cover</c> has been
            improved when it comes to handling list and bit string
            comprehensions (a counter for each qualifier), bit syntax
            expressions (the Value and Size expressions), and try
            expressions (the body called <c>Exprs</c> in the Reference
            Manual). A few (not all) situations where several
            expressions are put on the same line are also handled
            better than before.</p>

        <item>
            <p>When loading Cover compiled code on remote nodes 
            running code in the loaded module, a <c>badarg</c>
            failure was sometimes the result. This bug has been fixed.</p>

            <p>The short-circuit operators <c>andalso</c> and
            <c>orelse</c> are now handled correctly by the coverage
            analysis tool <c>cover</c> (it is no longer checked
            that the second argument returns a Boolean value.)</p>

          <p><c>make:files/1,2</c> can now handle a file in another

            extension in <c>Emakefile</c>, <c>make:all/0,1</c> looked
            for the object code in the wrong place.</p>
          <p>When specifying a file name including the <c>.erl</c>
            extension in <c>Emakefile</c> and some compile options
            for the file, <c>make:files/0,1</c> did not use the

          <p><c>cover</c>: When <c>cover:stop()</c> was called,
            the cover compiled code was not unloaded (as stated in
            the documentation) but simply marked as 'old'. This
            meant that processes lingering in (or with funs
            referencing to) the cover compiled code would survive
            even when the cover server and its ETS tables was
            terminated.</p>
          <p>Now the cover compiled code is unloaded, meaning that
            processes lingering in/with references to it will be
            killed when <c>cover:stop</c> is called, instead of
            later crashing with <c>badarg</c> when trying to bump
            counters in ETS tables no longer existing.</p>

          <p>Emacs: <c>erlang-man-function</c> and
            <c>erlang-man-module</c> used a pattern matching to find
            the requested module that sometimes yielded unexpected
            results. For example, <c>erlang-man-module file</c> would
            display the man page for <c>CosFileTransfer_File</c>.</p>

          <p>Some compiler warnings and Dialyzer warnings were
            eliminated in the Tools application.</p>
          <p>When tracing to a port (which <c>fprof</c> does),
            there could be fake schedule out/schedule in messages
            sent for a process that had exited.</p>

          <p>It is now possible to encrypt the debug information in
            beam files, to help keep the source code secret. See
            <c>compile(3)</c> for how to provide the key for encrypting,
            and <c>beam_lib(3)</c> for how to provide the key for
            decryption so that tools such as Debugger, <c>xref</c>, or
            <c>cover</c> can be used.</p>
          <p>The <c>beam_lib:chunks/2</c> functions now accepts an
            additional chunk type '<c>compile_info</c>' to retrieve
            the compilation information directly as a term. (Thanks
            to Tobias Lindahl.)</p>
