Should be safe to upgrade. Looking at the curve25519-dalek updates, other than the addition of new features, the only real breaking change is the deprecation and removal of FieldElement::as_bytes, which we don't use.
Summary of Changes in version 4.2.0:
- Move AVX-512 backend selection logic to a separate CFG flag that requires nightly
- Add Elligator2 hashing methods EdwardsPoint::hash_to_curve() and FieldElement::hash_to_field()
- Deprecate FieldElement::as_bytes in favor of FieldElement::to_bytes
- Remove deprecated FieldElement::as_bytes
- Add batch conversion function EdwardsPoint::to_montgomery_batch()
- Make VartimePrecomputedStraus::optional_mixed_multiscalar_mul() and VartimeRistrettoPrecomputation::vartime_mixed_multiscalar_mul() accept more points than static scalars
