+0.5 (IN PROGRESS)
+ - Change regression-test rules for Adam's compiler to use his
+ new front-end cql2xcql instead of the old cqlparse3.
+ - Fix comment in etc/pqf.properties (claimed that the Type-1
+ "string" attribute was "phrase"). Just a documentation
+ error.
+
+0.4 Thu Nov 21 10:09:26 2002
+ - 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 the XCQL output to include the nasty (but official)
+ <leftOperand> and <rightOperand> wrapper elements.
+ - Change the XCQL output to use the nasty (but official)
+ rendition of prefix-mapping: a <prefixes> element,
+ containing one of more <prefix>es may appear at the top
+ of either a <searchClause> or a <triple>.
+ - Include test/regression/xmlpp.pl in the distribution: this
+ may now be used for testing whether a CQL compiler produces
+ _equivalent_ XCQL to what's in the regression test, rather
+ than requiring byte-identical output.
+ - Include the reference XCQL output in the distribution, for
+ the regression test suite to run against.
+ - Change build process so that javadoc documentation is built
+ by "make" in the "docs" directory. There's now a top-level
+ makefile that builds the source, runs the test suite and
+ creates the documentation.
+ - 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.
+ - Remove the redundant and misleading etc/Grammar file.
+ - Fix up various Maintenance Agency web addresses that have
+ moved in the great ZING-release shake-up.
