+		Aligned with version 0.5 of the DTDs.
+		Added -d includes to dump out the include graph.
+		DTDs updated to verison 0.5.0.
+		Fixed DITA generator so that cxxInterface etc. is not written out.
+		Major fix to improve linking to #included files.
+		Added XML_DITA_OMIT_DUPLICATE_MEMBERS = YES to doxtemplate.txt

-Known issues
-============
+Known issues v0.1.7
+===================
+Missing content
+---------------
+Some classes have no members. There are approximately 1600 exported classes using the NONSHARABLE_CLASS macro. Doxygen is handling macros in 
+implementation files but not those in #included files. 
+
+Still losing whole components due to DITA-OT memory issues. This results in large groups of missing links.
 
-Doxygen produces a dialog box that appears under certain error conditions. 
-The dialog indicates that an error has occured with doxygen and this suspends the
-execution of doxygen until the ok button is pressed on the dialog.
-If doxygen is being run by a continuous integration system this dialog may be hidden.
-Invalid C++ is one known cause of this problem.
+Misplaced content
+-----------------
+There is an issue with content in the wrong components. Critically this leaves some libraries empty.
+
+Potential issues
+----------------
+There are still out of memory issues in DITA-OT, which are exacerbated by the “classes in wrong components” issue that is causing the maps 
+of some components to be larger than they should be.
 
-Doxygen has been known to take many days to run the full Symbian OS source.
-It is suspected that this is due to a large amount of page faults when ram runs low.
-Each doxygen process can use 500mb of ram and Raptor runs one doxygen process for each cpu.
-The space required for the working directory used by doxygen is greater than 80Gb.
-Please take this into consideration when choosing a build environment for Orb.
+Missing targets
+---------------
+Missing targets caused by command lines that are too long. Orb outputs a file (meta.xml) which outputs all the includes using echo. 
+Unfortunately there is a character limit on the command line so the entire echo doesn't get printed which means that the file is invalid.
