v0.9.0

• Reduced routing table churn #668
  • We now lock peers into the routing table once they enter the routing table unless they are:
    • Found in the early bootstrapping stages (in which case they are added on a probationary basis)
    • They fail to respond to a query from us (in which case they are evicted)
• Added peer diversity to the routing table #658
  • Allows us to restrict the routing table to only hold a limited number of peers with particular network attributes (e.g. IP address range, or ASN)
• Allow passing custom dual-dht options #671, #688
• Fixed key log encoding, now outputs keys in base32 encoded multibase #682
• Updated dependencies #689
