* Enhancements and Fixes*
  - Many corrections to docs and several translations almost complete.
    Andreas Schild who provided many corrections to core docs.
    PostGIS Japanese translation team first to reach completion of translation.

  - Support for PostgreSQL 10
  - Preliminary support for PostgreSQL 11
  - #3645, Avoid loading logically deleted records from shapefiles
  - #3747, Add zip4 and address_alphanumeric as attributes
           to norm_addy tiger_geocoder type.
  - #3748, address_standardizer lookup tables update
           so pagc_normalize_address better standardizes abbreviations
  - #3647, better handling of noding in ST_Node using GEOSNode
          (Wouter Geraedts)
  - #3684, Update to EPSG register v9
          (Even Rouault)
  - #3830, Fix initialization of incompatible type (>=9.6) address_standardizer
  - #3662, Make shp2pgsql work in debug mode by sending debug to stderr
  - #3405, Fixed memory leak in lwgeom_to_points
  - #3832, Support wide integer fields as int8 in shp2pgsql
  - #3841, Deterministic sorting support for empty geometries in btree geography
  - #3844, Make = operator a strict equality test, and < > to rough \ 
"spatial sorting"
  - #3855, ST_AsTWKB memory and speed improvements

* Breaking Changes *
  - Dropped support for PostgreSQL 9.2.
  - #3810, GEOS 3.4.0 or above minimum required to compile
  - Most aggregates now marked as parallel safe,
    which means most aggs have to be dropped / recreated.
    If you have views that utilize PostGIS aggs,
    you'll need to drop before upgrade and recreate after upgrade
  - #3578, ST_NumInteriorRings(POLYGON EMPTY) now returns 0 instead of NULL
  - _ST_DumpPoints removed, was no longer needed after PostGIS 2.1.0
    when ST_DumpPoints got reimplemented in C
  - B-Tree index operators < = > changed to provide better spatial \ 
locality on sorting
    and have expected behavior on GROUP BY.
    If you have btree index for geometry or geography, you need to REINDEX it, \ 
or review
    if it was created by accident and needs to be replaced with GiST index.
    If your code relies on old left-to-right box compare ordering,
    update it to use << >> operators

PostGIS 2.4.0rc3
2017/09/27
* Fixes and Enhancements since PostGIS 2.4.0rc2 *
  - #3781 st_contains cannot handle curvepolygon / compoundcurve
    consisting of only straight lines
  - #3866 server crashing from large values in ST_AsTWKB
  - #3818 Allow triangles unclosed in M to be WKT parsed
  - several packaging changes regarding checking trailing blanks

PostGIS 2.4.0rc2
2017/09/24
* Fixes and Enhancements since PostGIS 2.4.0rc1 *
  - Numerous fixes to ST_AsMVT, ST_AsGeoBuf
  - ST_AsTWKB speed and memory performance enhancments
  - ST_RepeatedPoints speed improvements
  - ST_ConcaveHull bug fix

See PostGIS 2.4.0 section for details of
new features and enhancements in this release.
