From Slashgeo:

The OSGeo-Announce mailing list informs us the open source GDAL/OGR 1.5.0 has been released. Considering the almost ubiquitous use of GDAL in open source and proprietary software, this is doubtlessly great news, especially with the numerous new drivers included for 1.5.0. Mateusz Loskot provides a few statistics: "more than 420 tickets closed on the Trac, implemented 17 new GDAL drivers for raster formats, and 4 new OGR drivers for vectors, implemented 4 (5 counting RFC 16) RFC documents, added 5 new command line utilities, plus, big number of features and improvements in SWIG bindings for scripting languages." In related news, Proj.4 4.6.0 has also been released.
