• Added -S option for non-multi geometries to shp2pgsql
• Updated heavily outdated README files for shp2pgsql/pgsql2shp by merging them with the manpages.
• Fixed MingW link error that was causing pgsql2shp to segfault on Win32 when compiled for PostgreSQL 8.2

It is finally official! After several years of unofficial “conformance” we recently took the plunge and submitted our PostGIS 1.1 compliance tests to the OpenGIS Consortium for testing. Last week we received the news that we are compliant. That means our web site can proudly display the OpenGIS button badge, and… well not much more than that. It is still the same database after all. But it is still nice to get some external validation.

The fourth annual world gathering of open source geospatial developers and users this year is FOSS4G in Lausanne, Switzerland from September 12-16. From the PostGIS development team, Paul Ramsey and Sandro Santilli (better known as "strk") will be in attendance and giving talks, we hope to see you there!
