tsearch v2

I will soon need to begin a project that requires full text searching
and I think I want to use tsearch.  I have installed the current version
and all is well but after doing some more research it looks like tsearch
v2 is substantially different from v1 (different operators, different
function names, etc).  Is tsearch v2 close enough to a stable version to
be used in a production setting?  I don't want to write something that
uses v1 and then have to turn around and patch in the v2 updates next
month...
