+Added support for specification of staticrank for grs-class of filters.
+This is enabled by using 'staticrank indexname' in .abs. Contents of
+indexname (elm ... indexname:w) is then used as value for staticrank.
+
+Implemented sorting via the ISAMB system. To enable, use sortindex:i in
+zebra.cfg.
+
+Added special retrieval support for sort keys. These keys can also be
+fetched using zebra::index:field:s
+
+Added support for specification of approximative limits for whole query.
+This is specified as attribute type 12. Semantics is the same as
+estimatehits in zebra.cfg.
