Would you mind elaborating on this? My vague recollection is that is could result in delays in downloading the block chain, but a more detailed explanation would be helpful. thx
0.3.20-0.3.23 have a bug where they refuse to upload
the full block chain to anyone, which makes block downloading very slow for other people. This was caused by a limit that was supposed to protect against certain denial of service attacks. Older versions don't have this buggy limit, but they don't have DoS protection, either.
