NetTopologySuite v2.0.0 Release Notes

Release Date: 2019-08-26 // over 4 years ago

  • 🚀 This major release represents several efforts to improve usability and consistency throughout NTS, brought on by some changes in JTS 1.16.0 that we felt would not be best to port as-is.

    🚀 As such, this release contains many breaking changes, some of which are very significant. Because the NuGet ecosystem heavily favors using SemVer for versioning, we felt that it's time to start deviating from using the JTS compatibility version numbering scheme that we have used in the past, and call this first release 2.0.0.

    Some of the breaking changes:

    📦 1. NetTopologySuite is, again, the primary NTS package.

    1. GeoAPI has been gutted. The relevant useful parts are now inside of NTS.
    2. Many interfaces have been removed, in favor of just using their corresponding classes. 👍 4. Coordinate.Z is no longer stored in a field on the base class. Full Z support is added by subclasses.
    3. Ordinate / Ordinates now define 16 spatial dimensions and 16 measure dimensions.
    4. ICoordinateSequence (now just CoordinateSequence) now uses integer ordinate indexes. 0️⃣ 7. By default, reading WKT without "Z", "M", or "ZM" tags using WKTWriter will now give a geometry that appears to support holding Z values, even if no Z values are actually present.
      • Set IsOldNtsCoordinateSyntaxAllowed to false to prevent this, but keep in mind that this will break things like "POINT (1 2 3)" that older versions of NTS supported.
