rust-secp256k1/CHANGELOG.md

[Unreleased]

• Update rand to 0.4 and gcc 0.3 to cc 1.0. (rand 0.5 exists but has a lot of breaking changes and no longer compiles with 1.14.0.)
• Remove PublicKey::combine from API since it cannot be used with anything else in the API
• Detect whether 64-bit compilation is possible, and do it if we can (big performance improvement)

0.10.0 - 2018-07-25

• A complete API overhaul to move many runtime errors into compiletime errors
• Update libsecp256k1 to 1e6f1f5ad5e7f1e3ef79313ec02023902bf8. Should be no visible changes.
• Remove PublicKey::new() and PublicKey::is_valid() since new was unsafe and it should now be impossible to create invalid PublicKey objects through the API
• Reintroduce serde support behind a feature gate using serde 1.0
• Clean up build process and various typos
