Release Notes

rust-fuzz/libfuzzer (libfuzzer-sys)

v0.4.9

Compare Source

Released 2025-01-28.

Added

• The example_init demonstrates how to pass an initialization code block to
  the fuzz_target! macro.

Changed

• The fuzz_target! macro now supports the generation of LLVMFuzzerInitialize
  to execute initialization code once before running the fuzzer. This change is
  not breaking and is completely backward compatible.

Added

  macro. See the example_crossover directory in this crate's repo for a
  complete example.
