+</li><li>The profiler tool can now process files with full thread dumps.
 </li><li>MVStore mode: the CLOB and BLOB storage was re-implemented and is
     now much faster than with the PageStore (which is still the default storage).
 </li><li>MVStore mode: creating indexes is now much faster
     (in many cases faster than with the default PageStore).
 </li><li>Various bugs in the MVStore storage and have been fixed,
     including a bug in the R-tree implementation.
+    The database could get corrupt if there were transient IO exceptions while storing.
 </li><li>The method org.h2.expression.Function.getCost could throw a NullPointException.
 </li><li>Storing LOBs in separate files (outside of the main database file)
     is no longer supported for new databases.
