Avail Light client v1.7.4

Node compatibility

• v1.8.0.2

Breaking changes

Added

• Introduced Avail keypair generation/import; first time client start generates a new keypair and saves the seed phrase to identity.toml file, on every subsequent start the private key is imported from the identity file
• Light client now supports initial version of UPnP protocol
• Introduced tracing on P2P event loop for easier triage
• Increased logging levels for finality checks

Changed

• Updated libp2p to 0.53.1 version; this update fixes some of the QUIC connection stability issues we had in the past
• Bootstrap nodes are now used as primary autonat servers; in order to mitigate existing autonat-over-quic libp2p errors, bootstraps TCP listeners are used for this purpose
• Fixed a data race bug that could sometimes occur on validator set change causing the client to crash with Not signed by this signature! error
• Fixed a genesis hash/system version/spec version storage bug
• Fixed a panic caused by a potentially empty cell arriving via DHT
• Updated default configs for existing networks
• Suppressed trace level logs from other crates not directly relevant to the light client
• Further code refactor introducing event loop abstraction in order to reduce unnecessary code duplication
