| Upgrade considerations:
 | |
| <ul>
 | |
| 
 | |
| <li>Since ProGuard now treats the <code>Exceptions</code> attribute as
 | |
|     optional, you may have to specify <code>-keepattributes Exceptions</code>,

 | |
| 
 | |
| <li>ProGuard now preverifies code for Java Micro Edition, if you specify the
 | |
|     option <code>-microedition</code>. You then no longer need to process the
 | |
|     code with an external preverifier.
 | |
| 
 | |
| <li>You should preferably specify <code>-repackageclasses</code> instead of the
 | |
|     old option name <code>-defaultpackage</code>.
 | |
| </ul>
