The PostGIS development team is proud to release a feature complete beta version of upcoming PostGIS 2.1.0. As befits a minor release, the focus is on speed improvements, more features, and bug fixes. While this beta release is feature complete, we expect some bugs and we'd appreciate it if you test it before final release and report back with any issues you run into so we can have a smooth release.
PostgreSQL versions supported in this release are PostgreSQL 9.0-9.3. PostGIS 2.1 is the first minor release to support PostgreSQL 9.3.
If you are currently using PostGIS 2.0+ (compiled with raster support) and PostgreSQL 9.1+, you can go the soft upgrade path:
ALTER EXTENSION postgis UPDATE TO "2.1.0beta3";
Users of 1.5 and below will need to go the hard-upgrade path.
Best served with a bottle of GEOS 3.4.0dev (still in development) and PostgreSQL 9.3beta2 (which will also be released in next week or so).
