+ <p>The HiPE compiler would badly miscompile certain
+ try/catch expressions, so it will now refuse to compile
+ modules containing try or catch.</p> <p>As a consequence
+ of this, <c>dialyzer</c> will no longer compile key
+ modules to native code.</p>

+ <p> By default Dialyzer inserts line breaks in types,
+ contracts, and Erlang Code when formatting results. Use
+ the new <c>--no_indentation</c> option to get the old
+ behavior of not inserting line breaks. </p>
