Downgrading warnings
--------------------
The 'chainstate' for this release is not always compatible with previous
releases, so if you run 0.9 and then decide to switch back to a
0.8.x release you might get a blockchain validation error when starting the
old release (due to 'pruned outputs' being omitted from the index of
unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate
data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan
the blockchain for missing spent coins, which will take a long time (tens
of minutes on a typical machine).
