Research direction

The report compares the blst entries in iohk-nix's flake.lock across cardano-node 11.0.1 and later releases, so start by reproducing the jq lookup in the issue against those lock files. The open question is whether the release notes should explain the libblst version change, which needs a maintainer decision on the expected wording. Done means a maintainer confirms the required version and the notes or a documentation change reflects it.

Summary
cardano-node 11.0.1 required libblst 0.3.15 but versions after require 0.3.14

Steps to reproduce

# Cardano node version:
CARDANO_NODE_VERSION=11.0.1

# IOHKNIX_VERSION:
IOHKNIX_VERSION="$(curl https://raw.githubusercontent.com/IntersectMBO/cardano-node/$CARDANO_NODE_VERSION/flake.lock | jq -r '.nodes.iohkNix.locked.rev')"

# Required dependencies:
# Fetch iohk-nix flake.lock, read SODIUM_VERSION SECP256K1_VERSION BLST_VERSION
read -r -d '' SODIUM_VERSION SECP256K1_VERSION BLST_VERSION < <(
  curl -s https://raw.githubusercontent.com/input-output-hk/iohk-nix/$IOHKNIX_VERSION/flake.lock | 
  jq -r '
    .nodes.sodium.original.rev,
    .nodes.secp256k1.original.ref,
    .nodes.blst.original.ref
  '
)

echo "Required versions:"
echo "SODIUM_VERSION=$SODIUM_VERSION"
echo "SECP256K1_VERSION=$SECP256K1_VERSION"
echo "BLST_VERSION=$BLST_VERSION"

Required versions:
SODIUM_VERSION=dbb48cce5429cb6585c9034f002568964f1ce567
SECP256K1_VERSION=v0.3.2
BLST_VERSION=v0.3.15

# Cardano node version:
CARDANO_NODE_VERSION=11.1.3

# IOHKNIX_VERSION:
IOHKNIX_VERSION="$(curl https://raw.githubusercontent.com/IntersectMBO/cardano-node/$CARDANO_NODE_VERSION/flake.lock | jq -r '.nodes.iohkNix.locked.rev')"

# Required dependencies:
# Fetch iohk-nix flake.lock, read SODIUM_VERSION SECP256K1_VERSION BLST_VERSION
read -r -d '' SODIUM_VERSION SECP256K1_VERSION BLST_VERSION < <(
  curl -s https://raw.githubusercontent.com/input-output-hk/iohk-nix/$IOHKNIX_VERSION/flake.lock | 
  jq -r '
    .nodes.sodium.original.rev,
    .nodes.secp256k1.original.ref,
    .nodes.blst.original.ref
  '
)

echo "Required versions:"
echo "SODIUM_VERSION=$SODIUM_VERSION"
echo "SECP256K1_VERSION=$SECP256K1_VERSION"
echo "BLST_VERSION=$BLST_VERSION"

Required versions:
SODIUM_VERSION=dbb48cce5429cb6585c9034f002568964f1ce567
SECP256K1_VERSION=v0.3.2
BLST_VERSION=v0.3.14

The same output is obtained for all cardano-node versions after 11.0.1.

Expected behavior
There would be an explanation regarding the requirement to downgrade the libblst library version in the release notes.

Which library version of libblst should be used to compile the latest cardano-node?
