	    In OTP-20.0, the behavior of c, make, and ct_make was

	    would be written to the directory where the source files
	    were found. This is now changed back to the old behavior

	    If a module includes eunit.hrl, a parse transform adds

	    cover data table. This is now corrected.</p>

	    In order to improve performance of the cover tool, new
	    functions are added for cover compilation and analysis on

          <p>
	    Some improvements of the data base access is also done in
	    order to improve the performance when analysing and
	    resetting cover data.</p>
          <p>

	    analyse_to_file is changed from no_source_code_found to

	    A new function, cover:flush(Nodes), is added which will
	    fetch data from remote nodes without stopping cover on
	    those nodes. This is used by test_server and common_test
	    when it is safe to assume that the node will be
	    terminated after the test anyway. The purpose is to avoid
	    processes crashing when re-loading the original beam if
	    the processes is still running old code.</p>
          <p>
	    Remote nodes will now continue to count code coverage if
	    the connection to the main node is broken. Earlier, a
	    broken connection would cause the cover_server on the
	    remote node to die and thus any still cover compiled
	    modules would cause process crash when trying to insert
	    cover data in ets tables that used to exist on the
	    cover_server. The new functionality also involves
	    synchronization with the main node if the nodes are
	    reconnected.</p>

	    If visiting a .yrl or .xrl file in emacs with

	    add user specified compiler options on form reloading</p>
          <p>
	    In order to be able to test non-exported functions from
	    another (test) module it is necessary to compile the
	    specific module (at least during the test phase) with the
	    export_all compiler option. This allows complete
	    separation of testing and productive code. At the moment
	    it is not possible to combine this with a test code
	    coverage using the cover module. The problem is that when
	    cover compiling a module using cover:compile_* the code
	    is reloaded into the emulator omitting/filtering the
	    passed user options. In my example above the export_all
	    option would be removed and the non-exported functions
	    cannot be called any more. (Thanks to Tobias Schlager)</p>

	    Inhibit electric newline after "-&gt;" when inside a type

          <p>
	    The Erlang mode for Emacs inserts a newline after every
	    "-&gt;", which saves you one keystroke when writing a
	    function, but that is inappropriate when writing a type
	    spec, as you'd normally keep the spec on one line. This
	    change inhibits the automatic insertion when the current
	    line starts with "-spec" or "-type".(Thanks to Magnus

	    Emacs has a facility for setting options on a per-file
	    basis based on comments in the source file. By default,
	    all options are considered "unsafe", and the user is
	    queried before the variable is set. This patch declares
	    the variables erlang-indent-level, erlang-indent-guard
	    and erlang-argument-indent to be safe, if the value
	    specified in the source file is valid.</p>
          <p>
	    Such declarations usually look like this:</p>
          <p>
	    %% -*- erlang-indent-level: 2 -*-</p>
          <p>
	    and appear on the first line of the file. (thanks to
	    Magnus Henoch)</p>

	    Cover has been improved to take less memory and allow
	    parallel analysis of cover data. Data collection from
	    nodes is now done in parallel and it is now possible to
	    issue multiple analyse and analyse_to_file requests at
	    the same time. A new function call async_analyse_to_file
	    has also been introduced, see the documentation for more
	    details.</p>

        Add lock profiling tool.</p>
          <p>
        The Lock profiling tool, lcnt, can make use of the
        internal lock statistics when the runtime system is built
        with this feature enabled.</p>
          <p>
        This provides a mechanism to examine potential lock
        bottlenecks within the runtime itself.</p>
          <p>
        - Add erts_debug:lock_counters({copy_save, bool()}). This
        option enables or disables statistics saving for
        destroyed processes and ets-tables. Enabling this might
        consume a lot of memory.</p>
          <p>
        - Add id-numbering for lock classes which is otherwise
        undefined.</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>
