This is a pre-release compatible with the Polkadot v0.8 runtime API and the Kusama and Polkadot networks.

New Features

  • use GlobalKeystore in lib/runtime package, update crypto runtime APIs accordingly
  • add BIP39 functionality for sr25519, update crypto runtime APIs accordingly
  • implement --rewind to rewind chain to a specific block for testing
  • handle block justifications when syncing, mark block finalized when a response is received and prune blocktree
  • update system_peers RPC call to return peer info collected from network handshakes
  • implemented persistent peerstore for the network; peerstore is now saved to disk

Improvements

  • filter out local addresses from advertised addresses
  • clean up trie.Trie API; no longer returns error for cases that don't error
  • update blocktree.getNode to check leaves of blocktree first, improving CPU usage
  • improve sync queue request management
  • update network scoring so that peers with highest score are requested from first

Bug Fixes

  • fix usage of trie.Snapshot and ensure previous tries don't get modified
  • if node shuts down abnormally, causing some database info to be missing, restart chain from last finalized block
  • update ext_misc_runtime_version_version_1 to return correct Version encoding
  • fix trie.ClearPrefix and trie.GetAllKeysWithPrefix based on syncing issues
  • replace trie.NextKey in TrieState with trie.GetAllKeysWithPrefix and manual iteration for now based on syncing issues
  • fix clearing of digests before execute_block call, enabling Polkadot compatibility

Deprecated

  • deprecated the legacy runtime API (v0.6)
