-----------------------------
== Of note:
Working Group - RDF and SPARQL:
Syntax (Turtle etc, SPARQL etc) are UTF-8 documents. UTF-8 does not
allow surrogate pairs. The RDF Working Group has decided not to allow
surrogate pairs via Unicode escapes.
In GeoSPARQL:
* upgrade SIS upgrade 1.4 -> 1.6
* support non-Euclidean geometries
In Fuseki:
* Memory leak fix related to long-running servers using Apache Shiro
In TDB:
* Robustness fix for the database after system level error
This affects both TDB2 and TDB1.
