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

• Add rand::distr::Alphabetic distribution. (#​1587)

Features

• Support std feature without getrandom or rand_chacha (#​1354)

error: failed to select a version for `rand`.

versions that meet the requirements `^0.9.1` are: 0.9.1

the package `crucible` depends on `rand`, with features: `min_const_gen` but `rand` does not have these features.
