* Update => SyncIntermediate * Added SyncObjects SyncIntermediate only updates whatever has changed, but, as a side effect, requires much more disk space. SyncObjects will only sync whatever is required for a block and will not save intermediate state to disk. As drawback this requires more time when more txs come in.
