Source](https://redirect.github.com/rust-fuzz/libfuzzer/compare/0.4.8...0.4.9)

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.
