Hi Giovanni,

gvSIG 2.0 has just started the stabilization process, and our plan is to 
release it in september. The APIs have been freezed since some time ago, 
so you can develep with it now if you can wait to september, your plugin 
should not be affected by API changes in the meanwhile.

If you can't wait or need any of the plugins that won't be initially 
available when gvSIG 2.0 is released, you can develop for the 1.11 
version. It also should not be affected when the 1.12 becomes available, 
as only corrections and new functionalities are allowed, not API changes 
(unless absolutely needed).

If you work with the 1.x APIs, you will have to make changes if you 
migrate it to the 2.0. How many will depend on which APIs you use, for 
example data access and persistence are new, but user interface related 
ones haven't changed much. If you already plan to do so, we have made a 
list of things to help in the migration:

http://www.gvsig.org/web/projects/gvsig-desktop/docs/devel/gvsig-devel-guide/2.0.0/howto-migrate-projects-to-gvsig-2-0

I would like to invite anyone who is or will migrate a plugin to gvSIG 
2.0 to share with us any instructions or tips he has used in the process 
so we can enrich the migration document.

Regards.
