[postgis-devel] [postgis-users] PostGIS 1.4.0 Released

We'll try to have windows binaries out by Monday and then the stack
installer/builder part probably week after.   So those who already installed
and RC just need to overwrite their binaries.  Nothing technically has
changed since most of the RC2->production were more on the testing scripts.
Unfortunately Mark Cave-Ayland is on vacation and I think since this is our
first time doing it, we should wait for him before we push to Stack Builder.
Oh by the way we just came back from OSCON and will be posting our slides
and data shortly which will showcase some of the speed improvements in 1.4
and taking advantage of PostgreSQL 8.4 features.  Should have those posted
sometime later today.

The PostGIS development team has, after a long period of meditation
and soul searching, released version 1.4.0 of the spatial data
extension for PostgreSQL.


This new version of PostGIS includes substantial performance
enhancements, more detailed reference documentation, new output
formats (GeoJSON) and an improved internal testing system. PostGIS 1.4
also supports the recent PostgreSQL 8.4 release.

Thanks to everyone who helped by testing during the release candidate
