The primary purpose of this release is to upgrade to JTS 1.15 (its first official LocationTech release).  Most Spatial4j users will not need to recompile (no API breakage) except those who expressly use JTS themselves.  This release adds JSON/Jackson ObjectMapper integration for shapes, and it has some other improvements too.
