v0.4.15

IMPORTANT:

If you're upgrading from an earlier release (other than the very short-lived v0.4.14), it's necessary to reconstruct the disk cache of compact blocks because the compact block serialization format has changed. To do this:

1. Shut down lightwalletd
2. Do either of the following:
   • rm -r /var/lib/lightwalletd/db then start the new lightwalletd (release v0.4.15), or
   • start the new lightwalletd with the option --redownload (this is needed only once, even if lightwalletd stops before it finishes syncing)

This will rebuild the local compact block disk cache. It will take several hours, depending on your hardware and network speed.

Note, if you store the database in a different directory than /var/lib/lightwalletd/db, using the --data-dir option, remove that directory instead.
