> 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/postgisinstallation.html#hardupgrade
> 
> Best served with a bottle of GEOS 3.4.1 and PostgreSQL 9.3beta2 (planned
> 9.1.0 release is September).

> Important / Breaking Changes
> 
>     #1653, Removed srid parameter from ST_Resample(raster) and variants
> with
> reference raster no longer apply reference raster's SRID.
>     #1962 ST_Segmentize* As a result of the introduction of geography
> support, The construct: SELECT ST_Segmentize('LINESTRING(1 2, 3 4)',0.5);

> rastercolumns now checks for existance of spatiallyunique and coveragetile
> constraints
>     ST_Intersects(raster, geometry) behaves in the same manner as
> ST_Intersects(geometry, raster).
