+1.8 IN PROGRESS
+ - API changes: more information hiding, introduce getters
+ - make some contants read-only
+
+
+1.7 Tue Jul 27 17:35:25 BST 2010
+ - Patch from Ralph LeVan to recognise
+ "qualifier.dc.creator"-like properties as well as
+ "index.dc.creator" -- backwards compatible with version
+ prior to 1.0 as well as those subsequent.
+ - Reinstate the "exact" relation even when v1.2 is in effect
+ (the default), despite its removal from v1.2 of CQL. In
+ practice, it seems to be in fairly widespread use, and
+ little real purpose is served in removing it.
+
+1.6 Thu Jun 17 10:56:24 BST 2010
+ - Fix the bug where "9x" is lexed as two tokens, a TT_NUMBER
+ followed by a TT_WORD, making unquoted search-terms such as
+ 2010-06-17 syntax errors. Thanks to Erik Hetzner
+ <erik.hetzner@ucop.edu> for the patch.
+
+1.5 Tue May 25 16:44:35 CEST 2010
+ - Fix recognition of word-relations to correctly match what is
+ specified in the CQL v1.1 and v1.2 documents. In
+ particular, "encloses" and "within" are recognised, so that
+ Masterkey's use of "encloses" for IP range authentication
+ works again.
+ - Update regression tests accordingly.
+ - Extend test/random/ to emit summary line of successful
+ recompilations.
