<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>
Application upgrade (appup) files are corrected for the

<c>asn1, common_test, compiler, crypto, debugger,
dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe,
inets, observer, odbc, os_mon, otp_mibs, parsetools,
percept, public_key, reltool, runtime_tools, ssh,
syntax_tools, test_server, tools, typer, webtool, wx,
xmerl</c></p>
<p>
A new test utility for testing appup files is added to
test_server. This is now used by most applications in
OTP.</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> In a file containing declarations and comments
without any empty lines between them, the
<c>recomment_forms()</c> function would associate a
multi-line comment with the declaration above it rather

<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
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
applications.</p>
