<p>
Extended error information for failing BIF calls as
proposed in <url
href="https://github.com/erlang/eep/blob/master/eeps/eep-0054.md">EEP
54</url> has been implemented.</p>
<p>
When a BIF call from the Erlang shell fails, more
information about which argument or arguments that were
in error will be printed. The same extended error
information will by <c>proc_lib</c>, <c>common_test</c>,
and <c>qlc</c> when BIF calls fail.</p>
<p>
For applications that wish to provide the same extended
error information, there are new functions
<c>erl_error:format_exception/3</c> and
<c>erl_error:format_exception/4</c>.</p>
<p>
There is a new <c>error/3</c> BIF that allows
applications or libraries to provide extended error
information in the same way for their own exceptions.</p>

<p>EEP-52 has been implemented.</p>
<p>In binary matching, the size of the segment to be
matched is now allowed to be a guard expression, and
similarly in map matching the keys can now be guard
expressions. See the Erlang Reference Manual and
Programming Examples for more details.</p>
<p>Language compilers or code generators that generate
Core Erlang code may need to be updated to be compatible
with the compiler in OTP 23. For more details, see the
section Backwards Compatibility in <url
href="http://erlang.org/eeps/eep-0052.html">EEP
52</url>.</p>

<item>
<p>The deprecated <c>erlang:get_stacktrace/0</c> BIF now
returns an empty list instead of a stacktrace. To
retrieve the stacktrace, use the extended try/catch
syntax that was introduced in OTP 21.
<c>erlang:get_stacktrace/0</c> is scheduled for removal
in OTP 24.</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

<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>
