+--- 2.0.20 2007/12/19
+
+Added experimental support for faceted results. This is implemented
+as a special retrieval on a result set and is triggered using element
+set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
+hit counts for field f1, type t1, field f2, type t2, .. The returned
+data is packed as XML or SUTRS depending on record syntax.
+
+Added support for Unicode-based indexing using ICU. This allows
+locale specific scanning, sorting. The implementation is based on
+the ICU utility part of YAZ 3.0.16 and later. See the manual as well
+as the examples/marcxml for an example of the use of ICU.
+
+--- 2.0.18 2007/09/19
+
+Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
+
+--- 2.0.16 2007/09/12
+
+Scan now returns a displayTerm which closer to the original word/phrase
+from original record.
+
+Added snippet support. Element set name zebra::snippet will make
+Zebra return an XML record with snippets (terms around matching terms).
+
+Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
+
+Fixed bug #1131: Missing value-of data in DOM filter.
+
+Fixed bug #1049: zebra.cfg lines with leading space are ignored.
+
+Fixed bug #1128: sortmax not honored.
+
+Fixed bug #1121: Crash for some searches with customized string.chr.
+
+--- 2.0.14 2007/05/09
+
+Zebra uses the YAZ 3 API. Note that this changes the Zebra API
+as well. The register layout is the same however. 
+
+Fixed bug #1114: scan within set may use excessive CPU.
+
+Fixed memory leak that occurred in scan.
+
+Fixed memory leak that occurred for each deleted record.
+
+Optimize updates of records where content is almost identical to previous
+version of record. This makes updating of the internal explain database
+faster too.
+
+For RPN queries the index type (w,p,..) may be specified verbatim as
+structure attribute with string value, e.g. @attr 4=w .
+
 Changed record update API . It is now handled by function
-zebra_record_update which does insert/replace/delete/update of 
-records . This function replaces zebra_record_{insert,delete} and
-zebra_admin_exchange_record.
+zebra_record_update which does insert/replace/delete/update of records .
+This function replaces zebra_record_{insert,delete} and
+zebra_admin_exchange_record. The DOM filter uses this feature and the
+@type attribute in record element specifies the action
+insert/replace/delete/update.
+
+Added support for multi-record updates (Bug #944). Based on patch from
+Hans-Werner Hilse.
