+
+Added new member 'query_charset' for bend_initrequest structure. A
+backend init handler should set this member to its native character set
+for query terms. When defined, the frontend server logic will announce
+this character set to a client if the negotiationModel bit is set by the
+client. ALL server implementors are encouraged to specify this. If they
+don't, a warning is issued.
+
+Added CCL utility to remove terms (stop words) from resulting RPN
+tree. This is handled by functions with prefix ccl_stop_words_ .
+
+New ZOOM C option, "rpnCharset", which allows client-side conversion of
+terms in RPN queries.

 Clean-up the CCL API. Moved some internal structures from ccl.h to 
 private header cclp.h. Changed ccl_parser_create so that a Bibset must
 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
