* 3753, Gist penalty speed improvements for 2d and nd points
(Darafei Praliaskouski)
* 3677, ST_FrechetDistance (Shinichi Sugiyama)
- Most aggregates (raster and geometry),
and all stable / immutable (raster and geometry) marked as parallel safe
* 2249, ST_MakeEmptyCoverage for raster (David Zwarg, ainomieli)
* 3709, Allow signed distance for ST_Project (Darafei Praliaskouski)
* 524, Covers support for Polygon-on-polygon, line on line,

**Enhancements**

* Support for PostgreSQL 10
* 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

* B-Tree index operators < = > changed to provide better spatial locality on
sorting
and have expected behavior on GROUP BY. It now works on exact geometry
instead of bounding box.
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.

* `_ST_DumpPoints` removed, was no longer needed after PostGIS 2.1.0
when ST_DumpPoints got reimplemented in C.
