rust-secp256k1-unsafe-fast/CHANGELOG.md

0.13.0 - 2019-05-21

• Update minimum supported rust compiler 1.22.
• Replace serialize_der function with SerializedSignature struct.
• Allow building without a standard library (no_std). std feature is on by default.
• Add human readable serialization to Signatures and SecretKeys.
• Stop displaying 0 bytes if a Signature is less than 72 bytes.
• Only compile recovery module if feature recovery is set (non-default).
• Updat rand dependency from 0.4 to 0.6 and add rand_core 0.4 dependency.
• Relax cc dependency requirements.

0.12.2 - 2019-01-18

• Fuzzer bug fix

0.12.1 - 2019-01-15

• Minor bug fixes
• Fixed cc crate version to maintain minimum compiler version without breakage
• Removed libc dependency as it our uses have been subsumed into stdlib

0.12.0 - 2018-12-03

• Overhaul API to remove context object when no precomputation is needed
• Add ThirtyTwoByteHash trait which allows infallible conversions to Messages
• Disallow 0-valued Message objects since signatures on them are forgeable for all keys
• Remove ops::Index implementations for Signature
• Remove depecated constants and unsafe ZERO_KEY constant

0.11.5 - 2018-11-09

• Use pub extern crate to export dependencies whose types are exported

0.11.4 - 2018-11-04

• Add FromStr and Display for Signature and both key types
• Fix build.rs for Windows and rustfmt configuration for docs.rs
• Correct endianness issue for Signature Debug output

0.11.3 - 2018-10-28

• No changes, just fixed docs.rs configuration

0.11.2 - 2018-09-11

• Correct endianness issue in RFC6979 nonce generation

0.11.1 - 2018-08-22

• Put PublicKey::combine back because it is currently needed to implement Lightning BOLT 3

0.11.0 - 2018-08-22

• 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
