Changes in Dataquay 0.9.1 since the previous version 0.9:

 * Update to support Qt5 and newer C++ compilers. Now requires C++11
   (though the library only makes minimal use of the standard).

 * Incorporate a number of build fixes


Changes in Dataquay 0.9 since the previous version 0.8:

 * Rework Uri, Node, and Triple constructors. Now Uri is to be used
   only for absolute URIs; Node demands that Uri be used when
   constructing URI nodes, treating a string as a literal type; and
   Triple demands three Nodes, losing the short-circuiting
   constructors that used to take relative URIs as strings.  This
   simplifies the rules for type usage: an absolute URI is a Uri, a
   literal is a string, and a relative URI must be expanded before it
   can be used. It also makes Triple construction patterns more
   consistent and easier to remember.

 * Add "slice" methods subjects(), predicates(), objects() to Triples

 * Rename matchFirst to matchOnce and queryFirst to queryOnce in Store
   API. There was no ordering by which the result could meaningfully
   be described as the first

 * Add Store::complete() to return a Node that completes a Triple with
   only one wildcard Node in it

 * Ensure store always has a base URI, and some fixes to base URI
   management for file loading (this will be reviewed again before
   1.0 though)

 * Fix lack of predicate-index in Sord backend

 * Formalise ObjectStorer in the same way as the formalisation of
   the ObjectMapper and ObjectLoader for 0.8

 * Replace ad-hoc unit tests with QtTest-based tests


Changes in Dataquay 0.8 since the previous version 0.3:

 * Add support for David Robillard's lightweight Sord datastore as an
   alternative to the existing Redland support.  The Dataquay Store
   now has a getSupportedFeatures() method to return capabilities of
   the underlying datastore.

 * Many fixes to ObjectMapper API, including a more formal approach
   to circular dependencies and formalising the object loading order

 * Add method to commit a transaction on a connection and
   simultaneously receive the set of changes

 * Hoist save() and import() to the Store interface from the
   BasicStore concrete class, and provide transactional
   implementations in TransactionalStore


Changes in Dataquay 0.3 since the previous version 0.2:

 * Add the entire ObjectMapper API and implementation

 * Add the ability to extend Node with new converters between QVariant
   types and RDF literal types

 * Replace QUrl with a new, very thin Uri class throughout for
   representation of RDF URIs.  QUrl turned out to be very costly for
   this and most of its facilities are not needed here

 * Change the Transaction interface so as to require an explicit
   commit() call rather than committing on delete (it's more work to
   use this way, but code written to use the old interface just didn't
   read well)

 * Change Node so as to use an untyped literal for string types rather
   than using xsd:string (necessary for practical interoperability)

 * Some very substantial performance improvements and further fixes


Changes in Dataquay 0.2 since the initial version 0.1:

 * Add the ability to control how duplicate triples are handled on
   import

 * Make the transactional store emit a signal when a transaction is
   committed

 * A small number of other fixes
