+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 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>.
+ - 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.)
+ - Include test/regression/xmlpp.pl in the distribution: this
+ is now used for testing whether a CQL compiler produces
+ _equivalent_ XCQL to the what's in the regression test,
+ rather than requiring byte-identical output.
+ - 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.
