Changelog

Entries are listed in reverse chronological order.

5.0.0

Change curve25519-dalek-ng dependency to curve25519-dalek. A major version bump is required because one cannot import curve25519-dalek and bulletproofs without conflicts.

4.0.0

Update to rand_core 0.6. This requires a major version bump but the API is otherwise unchanged from the 3.x series.

3.0.1

Update repository URL.

3.0.0

Add support for stable Rust.
Update curve25519-dalek and internal dependencies.
Tweaks to the (unstable) R1CS API.

2.0.0

Switch from failure to std-compatible errors via thiserror.
Update rand, curve25519-dalek, merlin versions.
Adds no_std support by @xoloki.

1.0.4

Change doc-include paths to allow compilation on the latest Rust nightly (which changed the path root).
Various changes to the (unreleased, unstable) R1CS implementation, which is disabled in the released version of the code.

1.0.3

Mistakes were made. Yanked and replaced by 1.0.4 above.

1.0.2

Updates the library to use the renamed functions in Merlin 1.1.
Adds additional validation checks to prevent identity points being used as part of a proof. This does not appear to have security content, but is intended as a defense-in-depth mechanism. See this comment for more motivation.
Documentation tweaks.

1.0.1

Tweaks to crate metadata.
Minor documentation changes.
Adds a regression test for deserialize-and-verify for proofs created using v1.0.0, to ensure they continue to verify in future versions.

1.0.0

Minor tweaks to the prerelease version.
Preliminary support for R1CS proofs, but this feature is hard-disabled in the published crate.

1.0.0-pre.0

Initial prerelease version, supporting single and aggregated range proofs, and multiparty proof aggregation.
