+See the bottom of this file for a list of things still to do.
+
+0.4 (IN PROGRESS)
+ - Add support for the new "phonetic" relation modifier,
+ including its mapping in "etc/pqf.properties".
+ - Make prefix-maps bind loosely, so that ``>dc=x a and b''
+ applies the dc=x binding to both the ``a'' and ``b''
+ sub-queries.
+ - Change build process so that javadoc documentation is built
+ by "make" in the "docs" directory.
+ - Write javadoc comments for CQLRelation and ModifierSet.
+ - Other improvements to javadoc comments (e.g. describe the
+ `config' parameter to the toPQF() method.)
+ - Sort out the licence: I've settled on the LGPL.
+
+0.3 Fri Nov 15 12:04:04 2002
+ - Allow keywords to be used unquoted as search terms.
+ - Add support for serverChoiceRelation (scr).
+ - Add support for prefix-mapping, as in
+ >dc="http://dublincore.org/ dc.title=fish
+ and
+ >"http://dublincore.org/ title=fish
+ The XCQL generated corresponds to Adam's suggested format
+ rather than Rob's, not so much because I prefer it (although
+ I do) as because it's what fell out when I just Coded What
+ Comes Natur'ly. That may need to change, depending on the
+ result of the ZNG list's deliberations.
+ - Fix the parser to normalise relation modifiers to lower case.
+ - Fix the CQLParser test harness not to emit an extraneous
+ blank line at end of XCQL output.
+ - Fix CQLNode documentation to contain a link to YAZ's
+ documentation of Prefix Query Format (PQF) rather than
+ containing a rather unhelpful chunk of BNF.
+ - Change the test/regression Makefile so that "make clean" now
+ does what "make distclean" used to do - the distinction
+ between them is pointless.
+ - Fix a few typos in the documentation.
+ - Move the README file's old "THINGS TO DO" section to the end
+ of this file, the new "Still to do" section.
