OTP.</p>

<p> A new checkbox has been added. When it is checked,
the range set by the <c>erl</c> flag <c>+pc</c> is used
for determining when to print lists of integers as
strings. When it is unchecked, integer lists are never
printed as strings. </p> <p>A minor incompatibility:
settings saved by Erlang R16B01 or later cannot be read
by Erlang R16B or earlier.</p>

Fix "OK" spelling in debugger messages and variables</p>
<p>
Simple code refactor in the debugger: renames all the
occurrences of "Ok" to "OK" in the code, variable names
and strings. This improves the consistency of the code
and follows the GTK UI where "OK" is always used.(Thanks
to Ricardo Catalinas Jiménez)</p>

<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>It is now possible to encrypt the debug information in

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
