 Builds upon the [virtual time control][opensavvy.prepared.suite.time] available out-of-the-box to allow
 [instancing clocks][opensavvy.prepared.compat.kotlinx.datetime.clock], [setting the current time][opensavvy.prepared.compat.kotlinx.datetime.set] or [waiting for a given time][opensavvy.prepared.compat.kotlinx.datetime.delayUntil].
 
+## Deprecation notice
+
+This module is built on top of the KotlinX.Datetime support for `Instant` and `Clock`, which have been removed in KotlinX.Datetime 0.7.0.
+
+`Instant` and `Clock` have been moved to the Kotlin standard library. The contents of this compatibility module have therefore been integrated into the main Prepared module, Prepared Suite.
+
+All functionality provided by this module is available in Prepared Suite, with a different package name.
+
+This module will not be updated in the future.
+
 ## Example
 
 We want to test a fictional `Scheduler` implemented using [KotlinX.Coroutines](https://kotlinlang.org/docs/coroutines-guide.html).
