Upgrade to 2.0 - STEMLab/geotools GitHub Wiki
GeoTools 2 can be considered an entirely different project from Geotools 1 (also known as Geotools-lite) because the changes between the two were so significant.
This time around we plan to focus on OGC standards; so you have documentation to read (that is not written by us).
We would like to welcome the addition of the SEAGIS project to the GeoTools team.
