1.0.1 (December 25, 2020)
This release fixes a soundness hole caused by the combination of
RwLockWriteGuard::mapandRwLockWriteGuard::downgradeby removing themapfunction. This is a breaking change, but breaking changes are allowed under our semver policy when they are required to fix a soundness hole. (See this RFC for more.)Note that we have chosen not to do a deprecation cycle or similar because Tokio 1.0.0 was released two days ago, and therefore the impact should be minimal.
Due to the soundness hole, we have also yanked Tokio version 1.0.0.
