    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
          <p>
	    The last tuple fun call has been removed from fprof.</p>
          <p>
	    Own Id: OTP-10091 Aux Id: seq12067 </p>
        </li>
        <li>
          <p>
	    Fix indentation of record fields in Emacs (Thanks to
	    Tomas Abrahamsson)</p>
          <p>
	    Own Id: OTP-10120</p>
        </li>
        <li>

	    Own Id: OTP-10121</p>
        </li>
        <li>
          <p>
	    Remove Erlang-specific compilation error regexp in

          <p>
	    Own Id: OTP-10168</p>
        </li>
        <li>
          <p>
	    Fix highlighting of atoms ending with a dollar sign</p>
          <p>
	    Like this: 'atom$'. In that example, the last single
	    quote should be recognised as ending the atom. This needs
	    a font-lock workaround similar to the one for strings.
	    Thanks to Magnus Henoch</p>

	    Own Id: OTP-10178</p>
        </li>
        <li>
	    <p> Xref now accepts filenames with character codes
	    greater than 126. (Thanks to Emile Joubert for reporting
	    the issue.) </p>

	    Own Id: OTP-10192</p>

<h3><a name="id66502">1.2 
        Tools 2.6.7</a></h3>

    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
          <p>
	    Makefiles in erts, hipe and tools have been corrected to
	    enable parallel make, i.e MAKEFLAGS=-jX where X is the
	    parallelity number. As a result of this dependencies were
	    corrected since that is what is needed for parallel make
	    to work.</p>
          <p>
	    Own Id: OTP-9857 Aux Id: OTP-9451 </p>
        </li>
        <li>
	    <p>Minor suppressions and fixes of compilation
	    warnings</p>
          <p>
	    Own Id: OTP-10016</p>
        </li>
      </ul>
    



<h3><a name="id66544">1.3 
        Tools 2.6.6.6</a></h3>

    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
	    <p>Update system profiling principles to reflect eprof
	    performance improvements.</p>
          <p>
	    Own Id: OTP-9656</p>
        </li>
        <li>
          <p>
	    [cover] fix leftover {'DOWN', ..} msg in callers queue</p>
          <p>
	    After stopping cover with cover:stop() there could still
	    be a {'DOWN',...} leftover message in the calling
	    process's message queue. This unexpected leftover could
	    be eliminated if erlang:demonitor/2 with option flush
	    would be used in certain points</p>
          <p>
	    Own Id: OTP-9694</p>
        </li>
        <li>
          <p>
	    Add deps as erlang-flymake include directory.</p>
          <p>
	    Update erlang-flymake to recognize the "deps" folder as
	    an include directory. This makes erlang-flymake
	    compatible with the rebar dependency management tool's
	    default folder structure, which puts included
	    dependencies in "deps".(Thanks to Kevin Albrecht)</p>
          <p>
	    Own Id: OTP-9791</p>

      </ul>
    


    <h4>Improvements and New Features</h4>
      <ul>
        <li>
	    <p>Variables are now now allowed in '<span class="code">fun M:F/A</span>' as
	    suggested by Richard O'Keefe in EEP-23.</p>
	    <p>The representation of '<span class="code">fun M:F/A</span>' in the
	    abstract format has been changed in an incompatible way.
	    Tools that directly read or manipulate the abstract
	    format (such as parse transforms) may need to be updated.
	    The compiler can handle both the new and the old format
	    (i.e. extracting the abstract format from a pre-R15 BEAM
	    file and compiling it using compile:forms/1,2 will work).
	    The <span class="code">syntax_tools</span> application can also handle both
	    formats.</p>
          <p>
	    *** POTENTIAL INCOMPATIBILITY ***</p>
          <p>
	    Own Id: OTP-9643</p>
        </li>
        <li>
          <p>
	    Tuple funs (a two-element tuple with a module name and a
	    function) are now officially deprecated and will be
	    removed in R16. Use '<span class="code">fun M:F/A</span>' instead. To make
	    you aware that your system uses tuple funs, the very
	    first time a tuple fun is applied, a warning will be sent
	    to the error logger.</p>
          <p>
	    Own Id: OTP-9649</p>
        </li>
        <li>
          <p>
	    Eliminate use of deprecated regexp module</p>

      </ul>
    



<h3><a name="id71102">1.4 
        Tools 2.6.6.5</a></h3>

    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
          <p>
	    Teach the emacs mode to compile yecc and leex files</p>
          <p>
	    If visiting a .yrl or .xrl file in emacs with
	    erlang-mode, then the `erlang-compile' function (normally
	    bound to C-c C-k), now knows how to compile yecc and leex
	    files, and then, if that compilation succeeds, also
	    compiles the resulting .erl files.</p>
          <p>
	    Also introduce a `erlang-compile-command-function-alist'
	    to make it possible to hook in other functions for
	    computing compilation commands/expressions, depending on
	    file name. (Thanks to Tomas Abrahamsson )</p>
          <p>
	    Own Id: OTP-9503</p>
        </li>
      </ul>
    


    <h4>Improvements and New Features</h4>
      <ul>
        <li>
	    <p> Bugs in xref(3) have been fixed. (Thanks to Matthias
	    Lang.) </p>

<h3><a name="id68927">1.5 
        Tools 2.6.6.4</a></h3>

    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
          <p>
	    Change make:files to behave more like erlc</p>
          <p>
	    This change removes the unnecessary checks on the files
	    when make:files is called and allows the error checking
	    to be done in compile:file, where the error messages are
	    produced. It does not affect the return value.</p>
          <p>
	    (Thanks to Sam bobroff)</p>
          <p>
	    Own Id: OTP-9179</p>
        </li>
        <li>
          <p>
	    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>
          <p>
	    Own Id: OTP-9204</p>
        </li>
        <li>
          <p>
	    Inhibit electric newline after "-&gt;" when inside a type
	    spec</p>
          <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
	    Henoch)</p>
          <p>
	    Own Id: OTP-9255</p>
        </li>
        <li>
          <p>
	    Add a check logic to prevent file descriptor leak</p>
          <p>
	    cover module handle files as raw in export and import.
	    Assert counts of ports are the same at the beginning and
	    at the end of the test case.(Thanks to Shunichi
	    Shinohara)</p>

<h3><a name="id69023">1.6 
        Tools 2.6.6.3</a></h3>

    <h4>Fixed Bugs and Malfunctions</h4>
      <ul>
        <li>
          <p>
	    Declare indentation options as "safe" in erlang-mode for
	    Emacs</p>
          <p>
	    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>

    <h4>Improvements and New Features</h4>
      <ul>
        <li>
          <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>
