v1.1.6-beta

This version fixed a few potential security problems found during the ongoing security audit. In addition, it fixed a problem that might cause join network failure.

Security

• Prevent last 2 elements in sigchain to be the same
• Returns error if proposal txn hash list contains duplicate
• Will not cache sigchain txn with invalid txn signature
• Use random neighbor probabilistically chance when stabilize
• Unify fee subtract and nonce increment logic for all txn types
• Check amount and fee range when checking payload

Network

• Connect to random neighbor first when joining the network to improve join reliability
