1.8.0 (2024-04-24) [YANKED]

NOTE: yanked due concerns over the MSRV bump. See #1067.

Barring unforeseen circumstances, this release aims to be the last 0.x release prior to a zeroize 1.0 release.

  • Disable zeroize_derive Cargo feature by default
  • Remove std feature in favor of alloc; MSRV 1.36+
  • Deprecate #[zeroize(no_drop)] attribute
