 			<title>Enhancements and fixes</title>

-			<p>Eclipse Memory Analyzer 1.8 has support for generating and analyzing dumps

-			from Java 9, Java 10 as well as Java 1.8 and previous versions.

-			The acquire dump dialog and collection queries have been enhanced for this.</p>

-			<ul>

-			<li>Memory Analyzer RCP is now built with Photon.

-			The following stand-alone builds are available:

+			<p>

+			One of the main enhancements is the <xref href="tasks/exportdump.dita">export HPROF</xref> query. This allows a new HPROF file to be generated from a snapshot,

+			with the redaction of data such as character or byte array values or field values. This could be useful

+			to allow future analysis of the new HPROF dump without exposing sensitive data.

+			</p>

+			<p>There is also a way to compare two heap dumps with a basic batch mode report using <xref href="tasks/batch.dita"><cmdname>ParseHeapDump</cmdname></xref>.</p>

+			<p>Memory Analyzer 1.8.1 also added more icons for queries and icons which worked better in high contrast or dark modes.</p>

 			<ul>

-			<li>Windows (x86)</li>

-			<li>Windows (x86_64)</li>

-			<li>Mac OSX (Mac/Cocoa/x86_64)</li>

-			<li>Linux (x86_64/GTK+)</li>

-			<li>Linux (PPC64/GTK+)</li>

-			<li>Linux (PPC64le/GTK+)</li>

-			</ul>

-			<note>

-			Because of the <xref format="html" href="https://dev.eclipse.org/mhonarc/lists/eclipse-dev/msg10207.html">removal of Eclipse platform support</xref> for certain operating systems for 

-			<xref format="html" href="https://www.eclipse.org/eclipse/news/4.7/platform.php#unix-platforms-dropped">

-			Oxygen</xref> and later the following stand-alone builds are not available for Memory Analyzer 1.8:

-			<ul importance="obsolete">

-			<li><i>Linux (PPC/GTK+)</i></li>

-			<li><i>AIX (PPC/GTK+)</i></li>

-			<li><i>AIX (PPC64/GTK+)</i></li>

-			</ul>

-			It is possible that Memory Analyzer 1.8 could be installed into 

-			<xref format="html" href="http://archive.eclipse.org/eclipse/downloads/drops4/R-4.6.3-201703010400/">

-			Eclipse Neon for those platforms</xref> or into 

-			<xref format="html" href="https://www.eclipse.org/mat/previousReleases.php">previous releases of Eclipse Memory Analyzer</xref>

-			but this has not been tested.

-			</note>

-			<note>

-			Because of the <xref format="html" href="https://wiki.eclipse.org/Eclipse/Installation/Java8Required">requirements of Eclipse Neon and later</xref>, Java version 1.8 or later is required to run the RCP.

-			<xref format="html" href="https://www.eclipse.org/mat/previousReleases.php">Previous releases of Eclipse Memory Analyzer</xref>

-			could run with Java 1.6, 1.7 and 1.8.

-			<li>Memory Analyzer can now work with Java virtual machines, version 9 and version 10,

-			as well as 1.8. Dumps from JVMs versions 1.5, 1.6 and 1.7 are still handled.
