| zcash_proofs | 0.8.0 | [qedit](https://hackmd.io/@qedit/zcash-nu5-audit) | Most of `zcash_proofs` got audited as part of the ECC audit, so we only need to audit the proof parameter download code in:

Note: there are duplicate `zcash_primitives`, `zcash_proofs`, and `reddsa` dependencies in Zebra's audit and development branches, [this will get fixed](https://github.com/ZcashFoundation/zebra/issues/6107) after the `zcashd` 5.4.0 release.
