* `AtomicReference` from `kotlin.native.concurrent` still requires freezing the `value`. Instead, you can use `FreezableAtomicReference` or `AtomicRef` from `atomicfu`. _Note that `atomicfu` has not reached 1.x yet_. * Prior to 1.6.20 `AtomicReference` from `kotlin.native.concurrent` still required freezing the `value`, and we suggested using `FreezableAtomicReference` instead.
Starting with 1.6.20 `AtomicReference` on the new MM behaves exactly like `FreezableAtomicReference`.
Alternatively, you can use `AtomicRef` from `atomicfu`. _Note that `atomicfu` has not reached 1.x yet_.
