PostGIS 2.3.0 Released

Author: Regina Obe 2016/09/26 in news ( release, 2.3, 2.3.0 )

The PostGIS development team is pleased to announce the release of PostGIS 2.3.0.
This is the first version to utilize the parallel support functionality introduced in PostgreSQL 9.6. As such, if you are using PostgreSQL 9.6, we strongly encourage you to use this version.

Parallel support will make many queries using PostGIS relationship operators and functions faster. In order to take advantage of parallel query support, make sure to set max_parallel_workers_per_gather to something greater than 0 as noted in max_parallel_workers_per_gather PostgreSQL runtime configs

Best served with [PostgreSQL 9.6+] which is due out this week and pgRouting 2.3.0 which also just got released.

Packages from maintainers will be out in the coming days and weeks.

If you are a Mac user using newer XCode 8, you might run into some compilation issues as a result of recent changes in XCode. Refer to https://trac.osgeo.org/postgis/ticket/3643 for a patch you can use.

Please report bugs that you find in this release.

PostGIS 2.1.9 Released

The PostGIS development team has uploaded the final release of the PostGIS 2.1 branch. The 2.1 branch is now end-of-life. As befits a patch release, the focus is on bugs and breakages.

PostGIS 2.4.0rc1 Released

We encourage everyone to test and in particular package maintainers to insure no surprises at final release time.

IMPORTANT NOTES

If you are upgrading from an existing PostGIS install, make sure after installing PostGIS 2.4.0rc1 binaries to do.

ALTER EXTENSION postgis UPDATE;

— if you have additional postgishy extensions below upgrade them too

ALTER EXTENSION postgis_sfcgal UPDATE;
ALTER EXTENSION postgis_topology UPDATE;
ALTER EXTENSION postgis_tiger_geocoder UPDATE;
--pgRouting 2.5.0 is imminent
ALTER EXTENSION pgrouting UPDATE;

In order to have Map Box Vector Tiles support enabled, you’ll need to compile with protobuf support and pkg-config to verify the correct minimum version of protobuf-c see protobuf for details. ST_FrechetDistance function will not be enabled if PostGIS is compiled with lower than GEOS 3.7.0. GEOS 3.7.0 will probably not be released before PostGIS 2.4.0 is out.
