	    <p>The abstract data type in <c>erl_syntax</c> is
	    augmented with types and function specifications.</p>
	    <p>The module <c>erl_prettypr</c> pretty prints types and
	    function specification, and the output can be parsed.</p>
	    <p>The types of record fields are no longer ignored. As a
	    consequence <c>erl_syntax_lib:analyze_record_field/1</c>
	    returns <c>{Default, Type}</c> instead of <c>Default</c>.
	    The functions <c>analyze_record_attribute</c>,
	    <c>analyze_attribute</c>, <c>analyze_form</c>, and
	    <c>analyze_forms</c> in the <c>erl_syntax_lib</c> module
	    are also affected by this incompatible change.</p>

	    <p> The default encoding for Erlang source files is now
	    UTF-8. As a temporary measure to ease the transition from
	    the old default of Latin-1, if EDoc encounters byte
	    sequences that are not valid UTF-8 sequences, EDoc will
	    re-try in Latin-1 mode. This workaround will be removed
	    in a future release. </p>

	    Fix reverting map in syntax_tools</p>
          <p>
	    There was a bug in erl_syntax when running e.g.
	    erl_syntax:revert_forms, affecting maps. Instead of
	    getting Key/Value you got Key/Key in the resulting
	    abstract form.</p>

          <p>
	    In syntax_tools-1.6.12 (OTP R16B03) a bug was introduced
	    which broke reverting of local implicit funs. Implicit
	    funs were mistakenly thought to be using abstract terms
	    for their name and arity. This has now been corrected.

	    <p>Variables are now now allowed in '<c>fun M:F/A</c>' as
	    suggested by Richard O'Keefe in EEP-23.</p>
	    <p>The representation of '<c>fun M:F/A</c>' 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 <c>syntax_tools</c> application can also handle both
	    formats.</p>

	    <p>The documentation is now possible to build in an open

	    some features are added in the documentation build
	    process. </p>
	    <p>- The arity calculation is updated.</p>
	    <p>- The module prefix used in the function names for
	    bif's are removed in the generated links so the links
	    will look like
	    "http://www.erlang.org/doc/man/erlang.html#append_element-2"
	    instead of
	    "http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
	    <p>- Enhanced the menu positioning in the html
	    documentation when a new page is loaded.</p>
	    <p>- A number of corrections in the generation of man
	    pages (thanks to Sergei Golovan)</p>
	    <p>- The legal notice is taken from the xml book file so
	    OTP's build process can be used for non OTP
