<h2>Debugger 2.2</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
Using several 'and's and 'or's in guards could crash the debugger.<br>
(Own Id: OTP-4630)<p>
</li>
</ul>
<!--- ################################################################# --->
<h2>Debugger 2.1</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
The Debugger can now handle more than 50 processes without crashing.
<br> Attach windows for dead processes will now disappear if
Edit->Clear is selected. <br> All modules in a directory are now shown
in the interpret dialog, but modules which are not compiled with the
debug_info flag are shown in parenthesis. <br> A few other bugs related
to error handling and popup windows are also fixed.<br>
(Own Id: OTP-4495)<p>
</li>
<li>
The Debugger handles funs somewhat better.
</li>
</ul>
<!--- ################################################################# --->
<h2>Debugger 2.0</h2>
<!--- ----------------------------------------------------------------- --->
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
Parts of the code, mainly for the GUI, has been rewritten in order
to make Debugger more robust and efficient. The functionality remains
the same but behaviour and appearance have changed slightly. Modules
must have been compiled with the option <CODE>debug_info</CODE> set
in order to be interpreted, only modules for which this is true are
shown in the Interpret window.
(Own Id: OTP-4201)<br>
</li>
<li>
The "Interpret Dialog" window no longer hangs if one tries to
debug-compile a module residing in a sticky directory.<br>
(Own Id: OTP-2665)<p>
</li>
</ul>
<h2>Debugger 1.5.4</h2>
<h3>Fixed errors and malfunctions</h3>
<ul>
<li>
Debugger crashed when trying to save or load settings if the default
directory <code>$HOME/.erlang_tools/debugger</code> had restricted
access.<br>
(Own Id: OTP-3244)<br>
(Aux Id: seq3852 in supportsystem)<p>
</li>
<li>
The debugger can now handle bit syntax construction in guards.<br>
(Own Id: OTP-3741)<p>
</li>
</ul>
<h3>Improvements and new features</h3>
<ul>
<li>
Code has been cleared up to get rid of compiler warnings.<br>
(Own Id: OTP-3728)<p>
</li>
<li>
The debugger now uses debugged information in beam files, instead of
compiling the modules to be debugged. That implies modules to be
debugged must be compiled beforehand and they must be compiled with
<code>debug_info</code> option. Also, there is no need to set any
include paths (because no compilation is done). The source code is
still needed for display purposes. <br> <p>The record editor has been
removed, as record names are no longer known by the debugger.<br>
(Own Id: OTP-4151)<p>
</li>
</ul>
<h3>Known problems</h3>
<ul>
<li>
The "Interpret Dialog" window hangs if one tries to debug-compile a
module residing in a sticky directory.<br>
(Own Id: OTP-2665)<p>
</li>
<li>
Included source code is not shown in the "Attached Process" window.<br>
(Own Id: OTP-3579)<p>
</li>
</ul>
<H2>Debugger 1.5.3</H2>
<H3>Fixed errors and malfunctions</H3>
<UL>
<LI>
The debugger could not be run in embedded mode, because the
dbg_ets module was not listed in the app file.
<br>Own Id: OTP-3829<br>
Aux Id: Seq 5084
<LI>
In some cases, the debugger would in a call to undefined
function <CODE>erts_debug:apply/4</CODE>. This problem has been
corrected.

<LI>You can't give an search path in the graphical interface where to look for include files. As a work around you can define the file/module to debug/interpret from the Erlang shell and give the search path as an option. To debug/interpret the module <CODE>foo</CODE> that contains the include directive <CODE>-include("bar.hrl").</CODE> in the directory "/my/include/dir" you can do one of:
<PRE>
1> ii(foo,[{i,"/my/include/dir"}]).
2> int:i(foo,[{i,"/my/include/dir"}]).
</PRE>
You can define a macro as well:
<PRE>
