# 0.73.2 (2026-09-08)

- Fixed various regressions with over/underaligned types with respect to 0.72 (#3449,#3453,#3458).
- Fixed a codegen regression with bitfields with enum types in some circumstances (#3455).

# 0.73.1 (2026-09-05)

# 0.73.0 (2026-09-05)
## Added
- Add `Debug`, `Clone` and `Eq` traits to `ParseCallbacks` info types (#3233).
- Include the source location in discovery `ParseCallbacks` (#3244).
- Report constants and variables in `ParseCallbacks::new_item_found` (#3249).
- Allow adding custom attributes to `extern` function blocks (#3257).
- Support new-type-alias constants (#3288, #3390).
- Support nested flexible array members (#3306).
- Add support for custom per-field attributes (#3307).
- Add const-generic bitfield accessors for compile-time optimization (#3325,
  #3374).
- Allow renaming struct and union fields (#3358).
- Add a `libcpp` feature to link `libclang` against `libc++` (#3375).
- Prebuilt binaries for aarch64 Linux (#3217).
## Changed
- Guarantee opaque type layout across all architectures (#3280).
- Use `NonNull` for C++ references (#3292).
- `Bindings::write` now takes `impl Write` instead of `Box<dyn Write>`
  (#3317, #3324).
- Optimize bitfield unit get/set with byte-wise operations (#3325).
- Emit `const` `__BindgenUnionField` accessors and comply with Rust 2024
  `unsafe_op_in_unsafe_fn` (#3337).
- Generate a doc comment pointing at the aliased type when a type alias is
  hidden (#3122).
- dyngen: convert the library path to `OsStr` before opening it (#3315).
- Return a `NoHeadersProvided` error instead of generating empty bindings
  when no input headers are provided (#3391).
- Bump the MSRV to 1.71 (#3401).
- Bump `syn` to v3 (#3401) and `shlex` to v2 (#3380).
## Removed
- Removed support for generating code for rustc versions < 1.51, along with
  the corresponding `RustTarget` constants (#3281).
- Removed the dependency on `itertools` (#3408).
## Fixed
- Fix a typo in the handling of `--rustified-non-exhaustive-enums` (#3266).
- Apply the same mangling rule to `C` and `C-unwind` function types (#3156).
- Fix alignment of bitfields in some edge cases (#3247).
- Fix typedefs inside constified modules (#3284).
- Fix generation of `f32` `NAN`, `INFINITY` and `NEG_INFINITY` constants
  (#3300).
- Allow constant expressions that don't fit in `i64` (#3301).
- Deduplicate derive traits added by the `add_derives` callback (#3296).
- Fix packed structs with flexible array members (#3305).
- Remove incorrect `size_t_is_usize` check (#3313).
- Prevent default derives for forward-declared types (#3110).
- Handle rustc version strings like `1.71.1-beta` and `1.71.1-nightly`
  (#3329).
- Centralize comment generation checks so comment options are respected
  everywhere (#445, #3330).
- Fix unnecessary transmute and unsafe warnings in bitfield codegen (#3335,
  #3388).
- Do not use the canonical declaration for enum type building (#3346).
- Allow zero-sized unions to be defined (#3348).
- Consolidate the `extern` block for functions and statics so shared symbols
  are only declared once (#3367, #3371).
- Propagate the implicit target to the macro fallback (#3382).
- Avoid an IR cycle for compiler-builtin ObjC typedefs shadowing themselves
  (#3387).
- Generate a `Debug` impl for new-type alias wrappers when the inner type
  only has a manual impl (#3411).
- Do not insert dummy fields into bitfields in cases where this would cause
  misalignment (#3431).
- Newtype aliases to c_void don't derive traits now (#3432).
## Security

# 0.72.1 (2025-08-31)

## Fixed

 * Fixed a bad interaction with upcoming clang 22 (#3278).

- Add the `--rust-edition` flag which allows to select which Rust edition to target. (#3002, #3013)
- Use `unsafe extern` instead of `extern` in blocks for any Rust target after 1.82. (#3015)
* Add the `ParseCallbacks::field_visibility` method to modify field visibility.
  actual visibility of the bitfields within the unit.
