PostGIS 1.5.2 is out   

The PostGIS development team is proud to announce the availability of PostGIS 1.5.2. Further details are on the postgis.org website PostGIS 1.5.2 release.

Leo and I are still working on the windows builds. As stated before the 32-bit builds will be out first. We are still preparing our 64-bit test environment on our new 64-bit laptop.

For those who are on 64-bit windows. Sami has some PostGIS 64-bit binaries for PostgreSQL 9.0 windows available on his blog. Though he just has the binaries available so you will need to use the other files from the 32-bit install.

To answer Sami's question, since he has asked it more than once: I really can't understand why PostGIS developers still want to compile the whole stuff using msys/mingw and that kind of stuff. We have Visual C++ (yes, the compiler is available for free), everything compiles with it and you don't have to whine about how hard it is to compile stuff for Windows because it's not GNU.
There are 3 reasons:

• Believe it or not -- the PostGIS development crew is relatively small and most work on Unix or MacOSX which do compile under GNU. Each builds there own regression tests. We need to be able to test consistently on all platforms which means we need a devlopment environment that all regression tests will work on without too much fuss. As much of a pain as we whine about with mSys -- its the most like what everyone else uses and mimicks the environment most consistently.
• Supporting VC means supporting yet another set of make and configure files and yuck project files. I don't even think express can deal with solution files. etc. GEOS does it and it was a pain for them. I know because a while back I would point out all the issues I was having compiling under VC++ (not to mention I don't need VC++) -- cause I'm a webdeveloper -- so don't have it normally installed). It took Mat some time to revise packaged scripts to even get PostGIS to compile under VS. There are people that bicker, but no one steps up to the plate wanting to support VS/VC++.
• Leo and I are predominantly web developers and database professionals; frankly in my ideal world everything would be interpreted or Just in time compiled (JIT) by the server. MingW / VS slash anything that needs compiling is just a big pain however I look at it and they are of equal pain to me. I got out of desktop development so I wouldn't need to deal with compiling stuff.

Okay we have whined enough. There are talks in the PostGIS and GEOS group of switching to CMake and to have a process that builds said make / project files so that we can more easily support GNU and VS without hopefully not adding too much extra work on anyone's plate. We will see how that goes. Will we compile the 64-bit version under Msys64 or VS -- we would like to do both and compare the 2. :)
