+	    <p>The <c>beam()</c> type in <c>beam_lib</c> is defined
+	    as <c>module() | file:filename() | binary()</c>. The
+	    <c>module()</c> is misleading. Giving the module name as
+	    an atom will only work if the BEAM file is in a current
+	    directory.</p>
+	    <p>To avoid confusion, <c>module()</c> has been removed
+	    from the type. That means that there will be a Dialyzer
+	    warning for code that call <c>beam_lib</c> with an atom
+	    as filename, but the calls will still work.</p>

+	    now override the actual file name in stack traces,
+	    instead of only affecting the return value of
+	    <c>Mod:module_info()</c>.</p>
+	    <p>The <c>+deterministic</c> flag will also affect stack
+	    traces now, omitting all path information except the file
+	    name, fixing a long-standing issue where deterministic
+	    builds required deterministic paths.</p>
