This version is not compatible with versions prior to 0.3.0, so
'git pull' and restart if you are following the alpha.
Changes from 0.2.5:
- All multicast frames are now signed by the original sender. This
will permit very efficient and fault tolerant rate limitation
across networks, and imposes a kind of "hash cash" cost on those
who wish to flood the network by forcing them to keep regenerating
new identities.
- Simplified peer last unicast / last multicast accounting.
- Improvements to multicast propagation algorithm to achieve better
coverage with less redundant messages.
- The bloated Switch class went on a diet, having packet decoding
broken out into PacketDecoder and multicast propagation algorithm
broken out into Multicaster.
- Multicaster is implemented as a template mockable class to permit
future simulations of huge scale multicast using the actual code
instead of mockups in another language.
- Introduced a faster non-cryptographic random source for things
like multicast propagation and address choosing.
- Some code cleanup, removal of outdated comments, etc.
