     is needed for manual invokation with `deferred_run()`.
 
   Following this change, `defer()` is now much faster (although still
-  slower than `on.exit()`). This also increases the compatibility of
-  `defer()` with `on.exit()` (all handlers are now run in the expected
-  order even if they are registered with `on.exit()`) and standalone
+  slower than `on.exit()` which is a primitive function and about as
+  fast as it gets). This also increases the compatibility of `defer()`
+  with `on.exit()` (all handlers are now run in the expected order
+  even if they are registered with `on.exit()`) and standalone
   versions of `defer()`.
 
+
+## Breaking change
+
 * When `source()` is used with a local environment, as opposed to
   `globalenv()` (the default), you now need to set
   `options(withr.hook_source = TRUE)` to get proper withr support
   (running `defer()` or `local_` functions at top-level of a script).
   THis support is disabled by default in local environments to avoid a
   performance penalty in normal usage of withr features.
