⚠️ If you're using NervosDAO with multisig, this upgrade is especially for you!

We've fixed a rare edge case in the multisig script, where unlocking could fail under specific conditions — especially when no since value was provided.

(Details: https://github.com/nervosnetwork/ckb-system-scripts/pull/98, https://github.com/nervosnetwork/ckb-system-scripts/pull/99)

If you're using older SDK, upgrade NOW—old versions may NOT be compatible and could cause unexpected behavior.

This update improves compatibility between multisig scripts and DAO withdrawals.

✅ What’s fixed:

- Contract logic now properly handles since conditions

- Added new test coverage

- All major tools updated for compatibility:

CCC SDK: https://github.com/ckb-devrel/ccc/pull/197

CKB SDK Rust: https://github.com/nervosnetwork/ckb-sdk-rust/pull/140

CKB SDK Go: https://github.com/nervosnetwork/ckb-sdk-go/pull/233

CKB SDK Java: https://github.com/nervosnetwork/ckb-sdk-java/pull/695

CKB CLI: https://github.com/nervosnetwork/ckb-cli/pull/631

CKB Explorer: https://github.com/Magickbase/ckb-explorer-public-issues/issues/844

Thanks for rolling with us! 🫡
