<td class="title">Configure start levels for feature based launch</td>
<td class="content">
<b>Feature-based Launch Configuration</b> now supports custom start levels and auto-start properties for individual plugins.
<p>
To configure them, you need to add the plugins via <b>Add Plug-ins...</b> first.
</p>
<p>
When launching a feature-based product, defined start levels and selected features are automatically
filled out in the created launch configuration. You can then select <b>features selected below</b> to
convert it to feature-based without any further configuration.

<td class="title">New Features view</td>
<td class="content">
You can now view the structure of features in your workspace projects using the new <b>Features</b> view.
<p>
To open the view, go to the <b>Show View</b> dialog (<b>Window &gt; Show View &gt; Other...</b>) and choose it from
the <b>Plug-in Development</b> category.
</p>
<p>
<img src="images/show-view-dialog.png" alt="" />
</p>
<p>
By default the view shows only features, with child features listed under their parents rather than at the top level.
The buttons on the view's toolbar allow plugins/fragments included within a feature to be shown, child features to be
shown at the top level, and for the hierarchy to be inverted (to show the features including each feature).

On any API addition that also results in a version change, a quickfix is now available that first
updates the version appropriately and then adds the <code>@since</code> tag based on the updated version.

<td class="title">Optimization in API tools builder </td>
<td class="content">
There are various optimizations that are done for API analysis builder which has
improved the performance in some scenarios tremendously.
<ul>
<li>Changing <b>Missing API baseline</b> option in <b>Preferences &gt; Plug-in Development &gt; API Baselines</b> preference page
updates the marker appropriately instead of doing a full build.</li>
<li>Removing or unchecking baseline in <b>Preferences &gt; Plug-in Development &gt; API Baselines</b> preference page removes all markers
which requires a baseline instead of a full build.</li>
<li>Removing or unchecking all API Use Scan locations in <b>Preferences &gt; Plug-in Development &gt; API Use Scans</b> preference page removes the relevant markers instead of doing a full build.</li>
</ul>
<p>
For example, changing <b>Missing API baseline</b> option in <code>org.eclipse.jdt.core</code> finishes instantaneously instead of 3 to 4 seconds earlier.

<td class="content">
Manually changing the settings file <b>.settings/org.eclipse.pde.api.tools.prefs</b> of a project
will result in a full project build, if the workspace auto-build is on.
<p>For the 4.13 release, it is possible to disable this new behavior with the VM property:
<b><span style="white-space: nowrap;">-Dorg.eclipse.disableAutoBuildOnSettingsChange=true</span></b>.
It is planned to remove this VM property in a future release.</p>
