v0.10.1

Compare Source

Fixed

• Reference to the rand crate in TryRng docs (#​75)

last significant breakage before 1.0. Code has moved from the rust-random/rand
repository to its own rust-random/rand_core.

• BlockRng::word_offset method (#​44)

Changed

[AArnott]

Attempted to rebase this update onto current main and resolve the failure.

rand_core 0.10 removes the getrandom feature. Workspace-pinning rand_core = 0.10 then fails resolution because pczt (via librustzcash) still requests rand_core with feature getrandom.

This looks blocked until downstream crates (especially pczt / librustzcash) support rand_core 0.10's feature set. Not including this in the bulk dependency PR for now.
