• XMLTester installed by default
• XMLTester code cleanup
• Fixed handling of collection input in GeometryFactory::buildGeometry
• Added shortcircuit test for Union operation
• Reduced useless Coordinate copies in CGAlgorithms::isPointInRing()
• Performance improvements in CGAlgorithms::isOnLine()
• Other minor performance improvements
• New Node::isIncidentEdgeInResult() method
• OverlayOp's PointBuilder performance improvement by reduction of LineIntersector calls
• Optimizations in Buffer operation
• Sever BUGFIX in DepthSegmentLT as suggested by Graeme Hiebert

The latest maintenance release of GEOS includes a number of bug fixes for special cases and processing issues discovered since the 2.1.1 release:

• Segfault fix in Point::isEmpty
• Mem Leak fix in OffsetCurveBuilder::getRingCurve
• Bugfix in LineSegment::reverse
• Added multipolygon buffering test in source/test/testLeaksBig
• Ported JTS robustness patch for RobustLineIntersector
• Removed useless Coordinate copies in OverlayOp::mergeZ()

• Stricter C++ syntax (math.h=>cmath, ieeefp.h in "C" block, ostringstream instead of sprintf)
• Better support for older compilers (Polygonizer::LineStringAdder friendship)
• Removed useless Coordinate copies in CGAlgorithms::isOnLine()
• Added support for polygonize and parametrized buffer tests in XMLTester
• Fixed support for --includedir and --libdir
• Fixed Z interpolation in LineIntersector
• Handled NULL results from getCentroid() in XMLTester
• Segfault fix in (EMPTY)Geometry::getCentroid()
• Made polygon::getBoundary() always OGC-valid (no LinearRings)
• Input checking and promoting in GeometryFactory::createMultiLineString()
• Segfault fix in GeometryEditor::editPolygon()

Refractions Research is honoured that PostGIS is a finalist in the 2005 VIATeC Technology Awards for Product of the Year!

The VIATeC awards celebrate the accomplishments of BC's fastest-growing technology region, and recognise companies, individuals and technologies demonstrating excellence, innovation and commitment to the technology community.

This release includes small bug fixes. The following issues have been resolved:

• Some incorrect escaping in shp2pgsql
• 3D computation in length_spheroid
• Multiple schema support improved
• Better join selectivity estimates
• Improved postgis_restore.pl script

After a long series of release candidates, the much anticipated 1.0.0 version of PostGIS has been released. The 1.0.0 version includes substantial changes over the original 0.X series, most importantly a new on-disk format which is both more compact and faster to access.

The 1.0.0 version is compatible with PostgreSQL 7.2 and higher, but is most tightly integrated with the PostgreSQL 8.0 and higher releases.

New features in 1.0.0 include:

A workshop on PostGIS and Mapserver will be presented by Paul Ramsey and Chris Hodgson at the 2005 Open Source GIS conference. The workshop will cover basic PostGIS, spatial SQL, tuning, and Mapserver tricks. We hope lots of PostGIS users can attend.

The sixth (and somehow yet still hopefully final) release candidate is now available, with bug fixes from RC5. Issues with multi() and other functions and architectures have hopefully been resolved. This version requires a dump and restore. Please test the postgis_restore.pl script. Please download it and try it out!

The fifth (and yet still hopefully final) release candidate is now available, with bug fixes from RC4. Issues with segfaults in some functions and architectures have hopefully been resolved. Please download it and try it out!
