These API specification versions may be used to indicate that a module
requires a certain API feature in order to function. For example, if you
see here a feature you need which is labelled <samp>1.20</samp>, your
manifest should contain in its main attributes the line:

<h3>
<a name="visible-ancestor">Find a visible ancestor of UpdateUnit</a>
</h3>
<em>Oct 31 '12; API spec. version: 1.37; affected top-level classes: <a href="./org/netbeans/api/autoupdate/UpdateUnit.html"><code>UpdateUnit</code></a>; made by: jrechtacek; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=190246">
#190246</a></em>
<br>
<p>
Added a method {@link org.netbeans.api.autoupdate.UpdateUnit#getVisibleAncestor} which returns a visible plugin
which depending upon this unit. Returns a unit if this unit is installed in the system and some of visible
units depending upon this one, otherwise returns null.

<br>
<p>
Added a <code>preferredupdate</code> attribute into <code>Update Center Descriptor</code>

<h3>
<a name="content-description">Added a method to get a descprition of content of Upadate Center</a>

<br>
<p>
{@link org.netbeans.api.autoupdate.UpdateUnitProvider#getContentDescription} returns
a description of content staging by this provider. The description might contains HTML tags e.g. HTML Links.

<h3>
<a name="get-license-id">Added a method to get ID of license agreement</a>
</h3>
<em>May 16 '12; API spec. version: 1.33; affected top-level classes: <a href="./org/netbeans/api/autoupdate/UpdateElement.html"><code>UpdateElement</code></a>; made by: jrechtacek; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=211736">
#211736</a></em>
<br>
<p>
Added a method {@link org.netbeans.api.autoupdate.UpdateElement#getLicenseId}
to get ID of license agreement if the <code>UpdateElement</code> has a copyright.
</p>
<p>
This ID could be stored somewhere once an user approves the license and
will not be asked for approval again the same license ID.
</p>

<h3>
<a name="check-write-permission">Check write permissions to installation directory</a>
</h3>
<em>May 16 '12; API spec. version: 1.33; affected top-level classes: <a href="./org/netbeans/api/autoupdate/InstallSupport.html"><code>InstallSupport</code></a> <a href="./org/netbeans/api/autoupdate/OperationException.html"><code>OperationException</code></a>; made by: jrechtacek; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=211777">
#211777</a></em>
<br>
<p>
<code>InstallSupport</code> find out the right directory where a plugin
should be installed. After that it checks if an user has privilege to write there.
In the case a lack of write permission, throws
{@link org.netbeans.api.autoupdate.OperationException.WRITE_PERMISSION}.
</p>
<p>
Beside this it allows to write into
<code>userdir</code> as a fallback in the case of insufficient privilege.

<h3>
<a name="nbm-external-size">Allowing to specify external NBM content size</a>
</h3>
<em>May 14 '12; API spec. version: 1.32; made by: jlahoda; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=212068">
#212068</a></em>
<br>
<p>
You can now specify the size of the external NBM content in the <code>.external</code> file
by using <code>SIZE:</code> property (e.g. <code>SIZE:42</code>). The size will then be incorporated
in the download size of the NBM.
</p>
<!-- AUTOMATICALLY GENERATED - DO NOT EDIT ME! -->
<h3>
<a name="nbm-external">External NBM contents</a>
</h3>
<em>Feb 10 '11; API spec. version: 1.24; made by: jtulach; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=195041">
#195041</a></em>
<br>
<p>
You can now ask that publicly downloadable files be included in an NBM.
Just replace <code>netbeans/file</code> with a text file <code>netbeans/file.external</code>
with lines:
</p>
<ol>
<li>
<code>CRC:123456789</code> to specify an expected CRC-32 checksum (nonnegative decimal format)</li>
<li>
<code>URL:http://.../...</code> to specify a download location (may be repeated to offer alternatives)</li>
</ol>
<p>
You can embed system properties in a URL using Ant-like syntax: <samp>http://.../feature-for-${java.specification.version}.nbm</samp>
</p>
<p>
The <code>&lt;makenbm&gt;</code> Ant task will automatically
avoid packing the actual file if the <code>*.external</code>
variant is also in the input cluster.
</p>
<p>
For convenience, the <code>org.netbeans.modules.maven.embedder</code>
module (if present) can also handle URLs of the forms
<code>m2:/org.grp:art:1.0:jar</code> or <code>m2:/org.grp:art:1.0:jar:javadoc</code>
which can take advantage of the local repository as a cache.

<h3>
<a name="custom-icons">Icons for update centers</a>
</h3>
<em>Jan 10 '11; API spec. version: 1.23; affected top-level classes: <a href="./org/netbeans/api/autoupdate/UpdateElement.html"><code>UpdateElement</code></a> <a href="./org/netbeans/api/autoupdate/UpdateUnitProvider.html"><code>UpdateUnitProvider</code></a>; made by: jtulach; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=183778">
#183778</a></em>
<br>
<p>
Define icon when specifying an update center using
<code>categoryIconBase</code> attribute.
</p>
<!-- AUTOMATICALLY GENERATED - DO NOT EDIT ME! -->
<h3>
<a name="new-operation-container">New operation type introduced together with method for create appropriate container</a>
</h3>
<em>Aug 19 '09; API spec. version: 1.11; affected top-level classes: <a href="./org/netbeans/api/autoupdate/OperationSupport.html"><code>OperationSupport</code></a> <a href="./org/netbeans/api/autoupdate/OperationContainer.html"><code>OperationContainer</code></a>; made by: dlipin; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=141714">
#141714</a></em>
<br>
<p>
New operation type - <code>OperationSupport.OperationType.INTERNAL_UPDATE</code> is introduced.
This operation can be used to find out elements which have updates and
which the particular element has the dependency on.
</p>
<!-- AUTOMATICALLY GENERATED - DO NOT EDIT ME! -->
<h3>
<a name="source-group-modifier">Feature enabled only when all its dependencies are enabled</a>
</h3>
<em>Apr 15 '09; API spec. version: 1.8; affected top-level classes: <a href="./org/netbeans/spi/autoupdate/UpdateItem.html"><code>UpdateItem</code></a>; made by: jtulach; issues: <a href="https://netbeans.org/bugzilla/show_bug.cgi?id=162673">
#162673</a></em>
<br>
<p>
The behaviour of <code>UpdateItem.createFeature().getInstalled().isEnabled()</code>
has been changed. Now it returns <code>true</code> only if
all dependencies are enabled.
