1.2.1 - 2020-08-21

Fixed

• Fixed problem that duplicated optional constraints during query planning.
• Fixed zero steps for transitive paths between nodes.

1.2.0 - 2020-08-19

Added

• User planning can now be selected with query options. Add :planner :user to the end of the query arguments.
• optional operator, as per the SPARQL OPTIONAL operation.
• Added show-plan function to observe how a query will be performed.

Changed

• Selecting variables as transitive attributes returns a path vector for that column.

Fixed

• Fixed issue with filter arguments sometimes failing.
• Transitive querying. Now handles unbound path elements better, planning is improved, and zero-steps are properly handled.
• Tuple selector in the :find clause now work for single elements, and with empty results.
• Single graph element in the :in clause now works.

1.1.0 - 2020-08-05

Added

• Attributes can be modified on entities by using the ' annotation (see Replacement Annotation doc for details)
• Arrays in entities can be appended to by using the + annotation on attributes (see Append Annotation doc for details)
• Queries now accept _ symbols as wildcards, and accept shortened constraints (not just triples)
• Introduce new :find clause syntaxes (see Find Clause Description doc for details)
• Created documentation for the API, data structures, querying, and creating transactions.

Changed

• Entities now represent multi-arity attributes as a set of values. If more than one of an attribute is found, then a set of those values is returned in the entity. Similarly, providing a set will result in using the attribute multiple times in the graph.

Fixed

• Entity arrays are now returned as vectors and not lists.

1.0.0 - 2020-07-29

Added

• New Datomic-style API
• Implemented Datom object for transaction reporting
