Key Highlights

  • Multi-field multipart payload builders in tests
  • Support for `Option<Vec<T>>` fields in `MultipartForm`
  • Bounded buffering (64KB cap) to prevent memory exhaustion
  • MSRV updated to 1.88

  • Memory safety improvements
  • MSRV bump to 1.88

Full Release Notes

## 0.8.0

- Add multi-field multipart payload builders to `actix_multipart::test`. [#3575]
- Add `MultipartForm` support for `Option<Vec<T>>` fields. [#3577]
- Bound internal multipart parser buffering to prevent unbounded memory growth on malformed bodies.
  - behavior change notice: There's now a cap for buffering (64KB). It can be changed with `MultipartConfig::buffer_limit`.
- Fix user-triggerable panic when parsing multipart boundaries.
- Minimum supported Rust version (MSRV) is now 1.88.
- Update `rand` dependency to `0.10`.
