[postgis-users] CVS Stability

[Paul Ramsey]

Generally speaking, it is safe to use the latest CVS version of 
PostGIS, as CVS differs from release mostly in having lots of minor bug 
fixes.

However, when major changes are afoot, the CVS can become 
unpredictable. You never know what you'll get.  This is one of those 
times.  Dave is shortly going to commit the first cut of code which 
uses the GEOS library (geos.refractions.net) to provide the remaining 
OpenGIS SFSQL functionality which we are currently missing.  Before 
these changes are really useful to the unwashed masses, we are going to 
have to (a) provide a stable GEOS release and (b) synchronize our 
PostGIS code to that release.  Right now there is no GEOS release, just 
the CVS. Hence the inherent instability of the PostGIS CVS. The code 
Dave is committing today is know to leak lots of memory. Beware.

To repeat: until the next numbered release (0.8) is out, do not use the 
CVS snapshots unless you are willing to work with experimental and 
tempermental code.
