            When interpreting a module, it is now checked that the
            module does not belong to the Kernel, STDLIB, GS or
            Debugger application, as interpreting a module used by
            the debugger/interpreter itself will lead to a deadlock
            or emulator crash.</p>
          <p>
            Also <c>int:interpretable(Mod)</c> has been extended to

	      (interpreted) module can be selected.</item>
	    <item>Auto Attach options can now be changed using
	      the buttons in the left part of the Monitor Window, not
	      only by the corresponding menu buttons.</item>

            Debugger can now handle <c>try-catch</c>. This meant

        <item>
            <p>It is now possible to encrypt the debug information in
            Beam files, to help keep the source code secret. See the
            documentation for compile on how to provide the key for
            encrypting, and the documentation for beam_lib on how to
            provide the key for decryption so that tools such as the
            Debugger, Xref, or Cover 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>
