Testnet - v1.9.0

This is a Testnet release. It is not recommended for Mainnet Beta

Changes

• Migrate from address maps to address lookup tables
• Optimized leader QoS service
• Add vote instructions that directly update on chain vote state
• Reject vote withdraws that create non-rent-exempt accounts
• Accountsdb plugin
• Adds fallback logic if retransmit multicast fails
• Create solana-poh and move remaining rpc modules to solana-rpc
• Parallelizes gossip packets receiver with processing of requests
• Add Incremental Snapshots
  • Incremental snapshots are effectively a diff of what's changed since the last full snapshot, and as a result, are much smaller
  • Currently opt-in; to enable, add the --incremental-snapshots flag when starting a validator

NOTE: This version of the solana-cli contains a bug in solana withdraw-from-vote-account ALL; it is recommended to NOT USE that command.

This release contains contributions from many people at Solana, as well as:

Tim Hagn, imprfekt, xuoe, Jarred Nicholls
