solana-labs/solana v1.5.5

Testnet - v1.5.5

on GitHub

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

Changes

• Save ~2GB memory on testnet and mainnet-beta by smarter validator's vote data allocation
• Fixed invalid snapshot generation under heavy RPC request load
• Enable validator accounts caching by default (the --accounts-db-caching-enabled flag is now silently ignored). The new --no-accounts-db-caching flag will disable accounts caching
• Introduce new, more clear and correct commitment terminology
• Add active installation version information to solana-install info subcommand
• Add solana calculate-rent subcommand
• Exchange and security best practices documentation improvements
• RPC, command-line and BPF VM stability fixes
• Reduce validator INFO log verbosity
• Upgrade to Rust v1.49.0
• New solana-test-validator arguments, --warp-to-slot and --clone, to better simulate aspects of mainnet-beta in a development environment
• Duplicate shreds are now broadcast through gossip
