Updates the requirements on rand to permit the latest version.

Changelog

Sourced from rand's changelog.

[0.9.5] — 2026-07-02

Fixes

  • Fix possible memory safety violation due to deserialization of UniformChar from bad source (#1803)

#1803: rust-random/rand#1803

[0.9.4] — 2026-04-13

Fixes

#1766: rust-random/rand#1766

[0.9.3] — 2026-04-11

This release back-ports a fix from v0.10. See also #1763.

Changes

  • Deprecate feature log (#1764)
  • Replace usages of doc_auto_cfg (#1764)

#1763: rust-random/rand#1763

[0.9.2] — 2025-07-20

Deprecated

  • Deprecate rand::rngs::mock module and StepRng generator (#1634)

Additions

  • Enable WeightedIndex<usize> (de)serialization (#1646)

[0.9.1] - 2025-04-17

Security and unsafe

  • Revise "not a crypto library" policy again (#1565)
  • Remove zerocopy dependency from rand (#1579)

Fixes

  • Fix feature simd_support for recent nightly rust (#1586)

Changes

  • Allow fn rand::seq::index::sample_weighted and fn IndexedRandom::choose_multiple_weighted to return fewer than amount results (#1623), reverting an undocumented change (#1382) to the previous release.

Additions
