This is a beta1 release, for testing and quality assurance, to be followed shortly by a final release. If you're interested in the stability and usability of PostGIS, please take a little time to ensure that you can build and use this release.


There have been a few changes since the alpha3 release.

 * Breaking changes *

  - #4214, Deprecated ST_Count(tablename,...), ST_ApproxCount(tablename, ...)
           ST_SummaryStats(tablename, ..),
           ST_Histogram(tablename, ...), ST_ApproxHistogram(tablename, ...),
           ST_Quantile(tablename, ...), ST_ApproxQuantile(tablename, ...) removed.
           (Darafei Praliaskouski)

 * Enhancements *

  - #4801, ST_ClusterKMeans supports weights in POINT[Z]M geometries (Darafei Praliaskouski)
  - #4804, ST_ReducePrecision (GEOS 3.9+) allows valid precision reduction (Paul Ramsey)
  - #4805, _ST_SortableHash exposed to work around parallel soring performance issue
           in Postgres. If your table is huge, use ORDER BY _ST_SortableHash(geom)
           instead of ORDER BY geom to make parallel sort faster (Darafei Praliaskouski)
  - #4625, Correlation statistics now calculated.
           Run ANALYZE for BRIN indexes to start kicking in.
           (Darafei Praliaskouski)
  - Fix axis order issue with urn:ogc:def:crs:EPSG in ST_GeomFromGML()
           (Even Roualt)
