| <h1>Eclipse Project 4.5 M3 - New and Noteworthy</h1> |
| <p>Here are some of the more noteworthy things available in the Mars milestone build M3 (2014-10-31) |
| which is now available for <a href="http://download.eclipse.org/eclipse/downloads/#4.5_Stable_Build" target="_top">download</a>. |
| <br/> |
| We also recommend to read the Tips and Tricks, either via <b>Help > Tips and Tricks...</b> or online for |

| <td class="content"> |
| You can enable automatic detection of periods when the Eclipse user interface is unresponsive: |
| <p> |
| <img src="images/ui-responsiveness-monitoring.png" alt="" /> |
| </p> |
| <p>UI freezes longer than the warning threshold are logged to the Eclipse error log |
| as warnings. The logged messages include one or more stack traces of the display |
| thread. Longer UI freezes are logged as errors and include stack traces of all threads. |
| Please keep in mind that capturing stack traces of all threads involves extra |
| overhead, so setting the error threshold below 1 second is not recommended.</p> |
| <p>A UI freeze is logged at the end of the freeze or after the deadlock threshold has |
| expired, whichever comes first. The latter condition facilitates logging of indefinite |
| UI freezes caused by deadlocks.</p> |
| <p>Please file bugs for the UI freezes you encounter, describe what you were doing |
| at the time, and include the messages from the error log related to the freeze.</p> |

| in favor of the more generic events <code>SWT.PreExternalEventDispatch</code> and |
| <code>SWT.PostExternalEventDispatch</code>, respectively. Clients that were written |
| using the old event names should be updated to refer to the new events. |

| GTK+ 2.18.0 or later (and its dependencies) will be the pre-requisites necessary to |
| run Eclipse successfully on all Linux/UNIX platforms as opposed to GTK+ 2.10.0 earlier. |
| Support for all versions older than 2.18 has been dropped effective Mars M3 milestone release. |
| <p> |
| Note: As of now, Eclipse logs a warning and continues to run when a GTK+ version older than 2.18.0 |
| is detected, but that behavior will soon be changed to not run Eclipse with unsupported versions. |

| <p>If you are injecting <code>org.eclipse.e4.core.services.translation.TranslationService.LOCALE</code> in your code, you |

| <img src="images/final-watchpoint.png" alt="" /> |
| </p> |
| This cannot be implemented for final variables with compile-time constant values |
| because Java compiles the constant value into class files and leaves no |
