| <h2>What's New in Eclipse 4.13</h2> |
| <p>Here are descriptions of some of the changes of interest to plug-in developers |
| made to the Eclipse Platform and SWT for the 4.13 release of Eclipse. |

| An extension was added to the generic editor so that it now can provide icons for content-type. See extension point <b>org.eclipse.ui.genericeditor.icons</b> for more details. |

| <code>org.eclipse.ui.quickaccess.IQuickAccessComputer</code> when using extension point <code>org.eclipse.ui.quickaccess/computer</code> |

| <td class="content"> |
| The org.eclipse.core.runtime bundle had <code>javax.inject</code> as an <b>optional</b> dependency, which it |
| previously reexported, but not anymore. |
| <p> |
| Technically, it's not a breaking change as <code>javax.inject</code> was never |
| guaranteed to be there thus whether it is reexported or not was not certain. Eclipse Platform can not guarantee the API stability of this package so it makes no |
| sense to make such a promise. |
| </p> |

| When using the E4XMIResource directly, transient UI elements are no longer filtered by default. |
| Note that transient UI elements are filtered by default when saved from the application. |
| |
| <p>To filter transient UI elements, call the save method with the new option |

| Earlier releases added support for tracing the correct usage of progress monitors. Unfortunately, this was missed while documenting in previous noteworthy documents. |
| |
| <p>To enable this tracing, add <code>org.eclipse.equinox.common/progress_monitors=true</code> in your ".options" file and start Eclipse via the -debug flag, or use the tracing option in the launch configuration. |

| <td class="content"> |
| The implementation of <code>ImageLoader</code> on GTK now uses the native <code>GdkPixbuf</code> API for image loading and saving. |
| <p> |
| Key highlights of the new ImageLoader on GTK: |
| </p> |
| <ul> |
| <li>Loading and saving images has native performance, with a significant speedup especially in loading JPEG files</li> |
| <li>Better GIF animation support</li> |

| <td class="title">Reduced ToolItem padding on GTK</td> |
| <td class="content"> |
| A fix in <code>ToolItem</code> has greatly reduced the size of some toolbars on GTK. |
| <p> |
| Previously, all <code>ToolItem</code>s were the same size as the largest of them in a given toolbar. With this fix, items are |
| now independently sized, which reduces the total size of toolbars that contain large items. |
| </p> |
| <p> |
| EGit's Rebase Interactive view is a good example of this fix. In the following screenshot, the toolbar shown on top has |
| the fix applied, compared to the larger, unpatched toolbar on the bottom. |

| The Text widget on Windows now supports displaying the search and cancel icons for <code>SWT.ICON_SEARCH</code> and <code>SWT.ICON_CANCEL</code> styles respectively. |
| With the Windows support added, these style APIs are now supported on all the three platforms and are no longer marked as a <code>HINT</code>. |
