This is a stable release suitable for use on Mainnet Beta

Changes

  • Expose validator RPC Pubsub subscription limit via CLI flag
  • Harden loader instruction checks
  • Add metrics for RPC Pubsub subscriptions and RPC health check
  • Update validator requirements docs with networking guidance

NOTE: A CI bug resulted in the v1.6.14 Linux binaries being built against Ubuntu 20.04 instead of the usual 18.04. As a result they are not compatible with the default 18.04 libc. If your validator is still running 18.04 you have three options

  1. Build the release from source [1] (recommended)
  2. Upgrade to Ubuntu 20.04 (schedule it even if you don't for this upgrade)
  3. Switch to the focal HWE kernel, which will pull in libc 2.29

You will see an error similar to the following when launching the process if effected:

/home/solana/.local/share/solana/install/active_release/bin/solana-validator: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /home/solana/.local/share/solana/install/active_release/bin/solana-validator)
  1. Follow the first two steps in the README, then run ./scripts/cargo-install-all.sh --validator-only desired/output/path

EDIT: Build steps updated
