Yanks and Regressions

0.2.2 through 0.2.8, 0.3.0 through 0.3.1, 0.4.0, 0.5.0, 0.6.0 through 0.6.5, 0.7.0 through 0.7.30

Security advisories for this bug have been published as RUSTSEC-2023-0074 and GHSA-3mv5-343c-w2qg.

In these versions, the Ref methods into_ref, into_mut, into_slice, and into_mut_slice were permitted in combination with the standard library cell::Ref and cell::RefMut types for Ref<B, T>'s B type parameter. These combinations are unsound, and may permit safe code to exhibit undefined behavior. Fixes have been published to each affected minor version which do not permit this code to compile.

See #716 for more details.

0.7.27, 0.7.28

These versions were briefly yanked due to a non-soundness regression reported in #672. After reconsidering our yanking policy in #679, we un-yanked these versions.
