This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
packaging changes:
- change to cmake/build.mk
- set test target (tests pass on NetBSD 10 amd64)
- update HOMEPAGE
- adjust revbumping instructions, because depending pcakages no
longer wrongly link to the C++ library
* NEWS: Changes in 3.13.0 (2024-09-06)
- New things:
- Add Angle::sinCosSnap to avoid small errors, e.g. with buffer operations (GH-978, Mike Taves)
- Add classes for curved geometry types: CircularString, CompoundCurve, CurvedPolygon, MultiCurve,
MultiSurface (GH-1046, Dan Baston/German QGIS users group/Canton of Basel-Landschaft/Canton of Zug)
- Support curved geometry types in WKT/WKB readers/writers (GH-1046, GH-1104, GH-1106, Dan Baston)
- 3D read and write support for GeoJSON (GH-1150, Oreilles)
- Port of RelateNG locationtech/jts#1052 (Martin Davis, Paul Ramsey)
- Rewrite of boolean predicates and relate matrix calculations
- "Prepared" mode now available for all predicates and relate matrix
- CAPI functions GEOSPreparedRelate and GEOSPreparedRelatePattern expose new functionality
- CAPI implementations of GEOSPreparedTouches, etc, that were previously defaulting
into non-prepared implementations now default into the RelateNG prepared implementation
- Prepared implementations for Intersects, Covers, still use the older implementations

- Breaking Changes
- Zero-length linestrings (eg LINESTRING(1 1, 1 1)) are now treated as equivalent to points (POINT(1 1)) in boolean predicates
- CMake 3.15 or later is requried (GH-1143, Mike Taves)

This secion restates the NEWS with a different organization.
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- Loading branch information
