The 2.1.0 release of PostGIS is now available.
The PostGIS development team is proud to release PostGIS 2.1.0. As befits a minor release, the focus is on speed improvements, more features, and bug fixes.
If you are currently using PostGIS 2.0+, you can go the soft upgrade path:
ALTER EXTENSION postgis UPDATE TO "2.1.0";If you are running 2.1.0 of beta or an unreleased version (and the above step fails with error “extension postgis has no update path from version x.x.x to version 2.1.0”) , you need to first copy the file in share\extensions\postgis—2.0.3—2.1.0.sql and change the 2.0.3 to the x.x.x noted in the error you are running. Then follow the above upgrade step again.
Users of 1.5 and below will need to go the hard-upgrade path documented in manual: http://postgis.net/docs/manual-2.1/postgis_installation.html#hard_upgrade
Best served with a bottle of GEOS 3.4.1 and PostgreSQL 9.3beta2 (planned release September).
