 ## Performance
 
  * The pre-validation of the cluster worker allotted to a future when
-   launched was unnecessarily expensive due to a thinko, e.g. it would
-   take ~0.1-0.2 seconds for a multisession future, whereas after the
-   fix it is effectly 0.0 seconds.
+   launched was unnecessarily expensive due to a thinko since
+   **future** 1.40.0 (2025-04-10), e.g. it would take ~0.1-0.2 seconds
+   for a multisession future, whereas after the fix it is effectly 0.0
+   seconds.
 
- * Cluster and multisession workers initiates more things when
-   created, e.g. pre-loading of packages and memoization of available
-   cores. Previously, such steps were performed only when the first
-   future was evaluated on a worker.
-
- * The **future** package is now pre-loaded on the parallel workers as
-   soon as a new cluster or multisession future backend is set
-   up. Previously, it was loaded with the first future being evaluated
-   on a worker.
- 
  * Calling `resolved()` on a lazy `ClusterFuture` would collect the
    result for the first _resolved_ future in order to free up one
    worker slot. Now this is only done if all slots are occupied. The
    net benefit is that lazy cluster futures will be launched faster,
    unless all workers are busy.

 ## Bug Fixes
 
  * Calls to `resolved()` were not registered by FutureJournal.
