Yes, I realize API version != file version. What I was getting at was that if I did something like

db = bsddb.hashopen("foo", "c")
db["1"] = "1"
db.close()

under the old bsddb module using Sleepycat 4.0.14, can I be assured that

db = bsddb.hashopen("foo")
print db["1"]
db.close()

will work with the new bsddb module?

There should be no surprises in the common case, yes?
