 - Consistent error handling of two `exec` overloads. (#10967)
 
+- Officially the following modules now have an unstable API:
+
+  - std/varints
+  - core/allocators
+  - core/hotcodereloading
+  - asyncstreams
+  - base64
+  - browsers
+  - collections/rtarrays
+  - collections/sharedlist

+  - concurrency/threadpool
+  - coro
+  - endians
+  - httpcore
+  - parsesql
+  - pathnorm
+  - reservedmem
+  - typetraits
+
+  Every other stdlib module is API stable with respect to version 1.
