0.4.9

• Fixed a bug where SeqCst protected loads were downgraded to Acquire on Windows, when the fast-barrier feature was enabled.

0.4.8

• Performance improvements.
• The fast-barrier feature flag enables runtime detection of fast memory barriers on Windows and Linux. It is enabled by default in this release.
• UnprotectedGuard is now #[non_exhaustive], preventing accidental guard usage that can lead to undefined behavior in safe code.

0.4.5

• Fixed a potential data race when using owned guards.

0.4.4

• Minor performance improvements.

0.4.3

• Minor performance improvements.

0.4.2

• Fix memory corruption bug when retire is recursively called during reclamation.
• Added a reclaim_all function to support recursive calls to retire.

0.4.1

• Added the Deferred type for deferred retirement batches.
• Minor performance improvements.

0.4.0

• Guards are now abstracted with a Guard trait.
• Guard renamed to LocalGuard.
• Added OwnedGuard, a guard that implements Send and Sync.
• Moved unprotected guard to functionality to the UnprotectedGuard type.
• Removed Collector::ptr_eq and added Guard::belongs_to.

0.3.0

Migration

• When migrating to 0.3.0, the type that is passed to a reclaimer is now *mut Link instead of Link. This means that any instances of link.cast::<T>() must be changed to link.cast::<Linked<T>>(), or Link::cast::<Linked<T>>(link). Any old reclaimers may now silently call ptr::cast instead of Link::cast, resulting in undefined behavior.

Changes

• Support for dynamically sized types through the AsLink trait.
• Guard::flush renamed to Guard::refresh, and a new Guard::flush operation added.
• Linked::into_inner was removed as value is now a public field.
• The seize::AtomicPtr alias has been removed.

0.2.0

• Added seize::AtomicPtr<T>, a type alias for std::AtomicPtr<Linked<T>>.
• Epoch tracking is now optional.
• Added Guard::flush.
• Retirement can now be delayed for the lifetime of a guard (Guard::retire).
• Added Linked::eq, Linked::into_inner.
• Added Collector::ptr_eq.
• Guard::unprotected is now const.
