Anyway, we needed a stable and up-to-date release of GAMA for the teaching. This has been done in the beginning of July and it is now available on the website. In addition, documentation have been updated and 2 new "epidemiological" tutorials have been created (french only for the moment).
Even though, the 1.4 version of GAMA is due quite soon, end of September, do not hesitate to test the 1.3 one as it includes a lot of "easying" GIS functions and improved general stability and performance!
