 <p>Here are some of the more noteworthy things available in milestone build M2

       SWT has added two new events, <tt>SWT.PreEvent</tt> and <tt>SWT.PostEvent</tt>,
       which are sent before and after all events and async runnables. These events can
       be used to measure the time spent on processing any events. This
       can be useful for detecting slow event listeners. Because of its pervasive effect
       on all events, this listener should be used with <b>extreme</b> caution.
       For an example of how this can be used, take a look at the
       <a href="http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.examples.watchdog">
       Watchdog</a> plugin in SWT examples.

      The target platform specified on the <b>Target Platform</b> preference page uses flexible target definitions, stored in .target files,
      to specify the set of plug-ins PDE should build against and use to launch applications. However, the content of the target platform
      was previously stored in preferences. This could lead to inconsistencies between what you expect to exist in the target platform and
      what is actually available. This problem was more noticeable when using a complex target definition containing feature or software
      site locations.

      <p>In Luna, the target platform information is always created from the target definition chosen on the preference
      page. In addition to reducing inconsistencies in the target, there are performance improvements when interacting with the
      target.</p>

       (to be finalized in March 2014).  Most of these
       were implemented as part of M1 also.  They are mentioned here again because
