Stein Series Release Notes

3.29.0

Prelude

This release includes optional support for fair locks. When fair locks are specified, blocking waiters will acquire the lock in the order that they blocked.

New Features

• We now have optional support for fair locks. When fair locks are specified, blocking waiters will acquire the lock in the order that they blocked. This can be useful to ensure that existing blocked waiters do not wait indefinitely in the face of large numbers of new attempts to acquire the lock. When specifying locks as both external and fair, the ordering within a given process will be fair, but the ordering between processes will be determined by the behaviour of the underlying OS.
