Mainnet - v1.13.5

This is a stable release suitable for use on Mainnet Beta

Release Notes

• Validators on 1.13.4 or 1.13.5 will no longer support the UDP protocol for transaction ingress by default. If you are currently using --tpu-disable-quic, make sure to remove it.
• 1.13.5 contains important QUIC client performance improvements - upgrading RPC nodes is strongly recommended.
• If you are building your own binaries make sure to use the correct Rust version as specified in ci/rust-version.sh (1.59 for v1.13). More recent Rust versions contain backwards-incompatible changes which break the QUIC library that Solana uses. Solana comes with a wrapper script ( ./cargo ) which automatically uses the correct version.
