<summary>dalek-cryptography/curve25519-dalek (curve25519-dalek)</summary>

### [`v5.0.0`](https://github.com/dalek-cryptography/curve25519-dalek/blob/HEAD/curve25519-dalek/CHANGELOG.md#500---2026-07-06)

##### Breaking Changes

- Update edition to 2024
- Update the MSRV from 1.60 to 1.85
- Remove `group-bits` feature due to soundness issues with underlying trait ([#&#8203;909](https://github.com/dalek-cryptography/curve25519-dalek/pull/909))
- Re-export `rand_core` ([#&#8203;908](https://github.com/dalek-cryptography/curve25519-dalek/pull/908))
- Rename `Scalar::batch_invert` -> `Scalar::invert_batch` for consistency. Also make it no-alloc. ([#&#8203;789](https://github.com/dalek-cryptography/curve25519-dalek/pull/789))
- Remove deprecated functions `FieldElement::as_bytes()` and `EdwardsPoint::nonspec_map_to_curve()` ([#&#8203;778](https://github.com/dalek-cryptography/curve25519-dalek/pull/778))
- Upgrade `rand_core` dependency to v0.10.0
- Upgrade `digest` and `sha2` deps

##### Other Changes

- Perf: Use maximum available NAF window size in `VartimePrecomputedStraus` ([#&#8203;848](https://github.com/dalek-cryptography/curve25519-dalek/pull/848))
- Perf: Skip checking 8 candidate points in `RistrettoPoint::lizard_decode` ([#&#8203;882](https://github.com/dalek-cryptography/curve25519-dalek/pull/882))
- Add Lizard bytes-to-point injection for Ristretto. Gated under `lizard` feature. ([#&#8203;826](https://github.com/dalek-cryptography/curve25519-dalek/pull/826))
- Add an allocating batch inversion called `Scalar::invert_batch_alloc` ([#&#8203;789](https://github.com/dalek-cryptography/curve25519-dalek/pull/789))
- Add `Scalar::div_by_2` ([#&#8203;805](https://github.com/dalek-cryptography/curve25519-dalek/pull/805))
- Add `EdwardsPoint::hash_to_curve` ([#&#8203;786](https://github.com/dalek-cryptography/curve25519-dalek/pull/786))
- Undeprecate `Scalar::from_bits()` ([#&#8203;780](https://github.com/dalek-cryptography/curve25519-dalek/pull/780))
- Use constant-time equality testing for compressed Ristretto and Edwards points, rather than autoderived equality
