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

Deprecated

• deprecated the legacy runtime API (v0.6)

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

New Features

• compatible with Polkadot v0.8 runtime API (go-wasmer)
• networking up-to-date with substrate as of Feb 25 2021 (discovery, message exchanges tested and working with Kusama)

• add preliminary support for the perlin/life wasm interpreter
• add BABE secondary slot authorship verification
• update BABE digests to be compatible with substrate and correctly set next epoch data

Improvements

• merkle-patricia trie database backing refactored to store trie nodes individually in database
• fix usage of trie node "dirty" bit, use this when writing to database

• network improvements based on CPU profiling; read/write directly to/from same stream when syncing, improve allocations
• syncing algorithm improved to queue block data while currently processing data
• basic scoring and pruning added to sync algorithm; don't disconnect from preferred peers

Bug Fixes

• runtime upgrades fixed and tested with Kusama
• runtime bug where values were not being correctly copied before placed into trie fixed
• use __heap_base as allocator offset for runtime
• fix BABE threshold calculation to match substrate
