Changelog

1.0.1 — 2023-04-03

  • CMake and build improvements. #230 #231

1.0.0 — 2022-08-25

  • Removed: Deprecated function ethash_verify() has been removed. Use ethash_verify_against_boundary(). #226

0.9.0 — 2022-04-05

  • Added: The constant ETHASH_MAX_EPOCH_NUMBER = 32639 representing the maximum supported Ethash epoch. #212
  • Removed: Previously deprecated ProgPoW implementation. #207 #209 #210
  • Removed: Support for using custom hash function for light cache generation. #213
  • Removed: The internal header builtins.h. #208

0.8.0 — 2021-11-09

  • Added: The new set of functions which verify Ethash hashes against difficulty has been added to the library: verify_against_difficulty() and verify_final_hash_against_difficulty(). These functions improve usability by omitting previously required difficulty to boundary conversion. The old verification function is still available under the verify_against_boundary() name but its usage is discouraged. #195
  • Added: The dedicated procedure to convert difficulty to boundary ethash_difficulty_to_boundary() has been added to the testing infrastructure but can be promoted to the public API if requested. #191
  • Deprecated: verify() has been deprecated and replaced with verify_against_boundary(). #193
  • Deprecated: verify_final_hash() has been replaced by verify_final_hash_against_difficulty(). #200
  • Deprecated: The ProgPoW support has been deprecated and will be removed in the next release. #201
  • Changed: The internal hash type comparison operators have been optimized and the dependency on the memcmp() function has been dropped. #186
  • Changed: Verification functions now return error codes instead of bool with additional information about which verification check has failed. #187
    • In C API error codes are represented by the ethash_errc enum,
    • In C++ the error codes are wrapped into std::error_code.
  • Changed: Some build requirements have been increased.
    • C11 is required (previously C99), #188
    • C++14 is required (previously C++11), #189
    • CMake 3.16 is required (previously 3.13), #205
    • Python wheels are now built with manylinux_2_24. #194

0.7.1 — 2021-08-26

  • Added: Support for building with clang-cl (LLVM-based toolchain for Visual Studio 2019). #179 #180 #182 #183 #184

0.7.0 — 2021-05-26

  • Changed: The global context API (aka "managed" API) has been moved to separate library ethash::global-context and ethash/global_context.hpp header. #175
  • Added: CMake options to disable building of individual libraries:
    • -DETHASH_BUILD_GLOBAL_CONTEXT=NO disables building ethash::global-context.
    • -DETHASH_BUILD_ETHASH=NO disables building ethash::ethash and ethash::global-context. Only ethash::keccak is built then.
  • Added: Basic support for building to WebAssembly #175

0.6.0 — 2020-12-15

  • Added: The ethash::keccak library received the optimized Keccak implementation which uses BMI and BMI2 x86_64 extensions. This implementation is automatically selected at startup provided the used extensions are available in the hardware. #162 #168

0.5.2 — 2020-08-03

  • Fixed: Fix compilation with MSVC/C++17. #154

0.5.1 — 2020-01-30

  • Added: Experimental Python bindings — ethash package. #123 #138
  • Added: More functions exposed in C API. #136
  • Changed: ProgPoW implementation updated to revision 0.9.3. #151

0.5.0 — 2019-06-07

  • Changed: The Keccak implementation has been moved to separate library "keccak", available as ethash::keccak target in the ethash CMake package. #131

0.4.4 — 2019-02-26

  • Fixed: Fix compilation on PowerPC architectures (-mtune=generic not supported there). #125

0.4.3 — 2019-02-19

  • Added: The public version.h header with information about the ethash library version. #121
  • Added: Ethash and ProgPoW revisions exposed as {ethash,progpow}::revision constants. #121

0.4.2 — 2019-01-24

  • Fixed: The progpow.cpp file encoding changed from utf-8 to ascii.

0.4.1 — 2018-12-14
