Singular 0.4.1 — upstream Merkle Patricia Forestry, and one more proof shape accepted
A fix release on top of 0.4.0, same lifecycle, same archive layout.
- Absence proofs whose root is a lone Fork are now accepted on chain. The vendored patch of the Merkle Patricia Forestry library is replaced by upstream v2.1.0, which fixes the
excludingarm that refused them. With real keys this shape appears within a handful of registrations, so it mattered before any public-network run. The state script hash moves accordingly. - The proof-variant rows (CS07) now execute on a devnet in CI with receipts, instead of being marked.
Use it
Same as 0.4.0: download the archive and SHA256SUMS, check, extract, bash verify-identities.sh, then follow README.md inside for the devnet journeys.
Limits
Devnet only; the archive replay still needs CANDIDATE_SHA set to the release commit. Both change in 0.5.0.
