The 3.13 release of GEOS is now available to download.

The headline features of this release are:

- A new approach to boolean predicates via RelateNG

  - Faster performance for many cases where a short circuit is available
  - Avoiding the full computation of a topology graph for every call
  - Ability to use a high speed “prepared” approach for the complete set of predicates as well as the relate matrix functions

- Initial support for ISO SQL/MM curve types

  - Create, read and write support for CircularString, CompoundCurve, CurvedPolygon, MultiCurve, MultiSurface

This release includes the following new features in the C API (and of course underlying changes to the C++ code to support these features):

- GEOSGeom_createEmptyCircularString() creates a new empty CircularString
- GEOSGeom_createCircularString(coordseq) creates a CircularString with the supplied coordinates
- GEOSGeom_createEmptyCompoundCurve() creates a new empty CompoundCurve
- GEOSGeom_createCompoundCurve(curves, ncurves) creates a CompoundCurve with the supplied components (start/end coordinates must match up)
- GEOSGeom_createEmptyCurvePolygon() creates a new empty CurvePolygon
- GEOSGeom_createCurvePolygon(shell, holes, nholes) creates a CurvePolygon with the supplied rings
- GEOSPreparedRelate(prepgeom, geom) generates a DE9IM intersection matrix for the geometry pair, where one input has been “prepared” for fast repeated calls
- GEOSPreparedRelatePattern(prepgeom, geom, pattern) tests a pair of geometry against a known DE9IM pattern to see if the relationship is consistent with the pattern

Thanks to everyone who contributed to this release!
