PostGIS 1.5.2 coming soon

Over the past two weeks, the PostGIS development team has been working hard to get out PostGIS 1.5.2 in time for the PostgreSQL 9.0 release. This release contains fixes allowing PostGIS to compile against 9.0. Due to an unfortunate turn of events, we missed the cut by a couple of days and are currently experiencing technical difficulties with the website. These should be resolved soon and barring no further difficulties, we should have the final PostGIS 1.5.2 ready late this week.

On the plus side, we do have a PostGIS 1.5.2 rc1 available for download from our PostGIS Wiki Release Candidate Downloads section. Please feel free to test these out so that we have a smooth release.

We should have windows binaries available a short time after release. Unfortunately we do not have the 64-bit windows build ready yet, so you still have to use the 32-bit version of PostgreSQL 9.0 if you need PostGIS on windows.
