Changes in 0.6.0 (Tue Feb 04 2014)
- Fix an issue when parsing scripts which contain invalid signatures that
caused a chain fork on block
0000000000000001e4241fd0b3469a713f41c5682605451c05d3033288fb2244
- Correct an issue which could lead to an error in removeBlockNode
(https://github.com/conformal/btcchain/issues/4)
- Improve addblock utility as follows:
- Check imported blocks against all chain rules and checkpoints
- Skip blocks which are already known so you can stop and restart the
import or start the import after you have already downloaded a portion
of the chain
- Correct an issue where the utility did not shutdown cleanly after
processing all blocks
- Add error on attempt to import orphan blocks
- Improve error handling and reporting
- Display statistics after input file has been fully processed

- Resuming the chain sync from any point before the final checkpoint
will now use headers-first mode
(https://github.com/conformal/btcd/issues/69)
