+*   In `:zeitwerk` mode, eager load directories in engines and applications only
+    if present in their respective `config.eager_load_paths`.
+
+    A common use case for this is adding `lib` to `config.autoload_paths`, but
+    not to `config.eager_load_paths`. In that configuration, for example, files
+    in the `lib` directory should not be eager loaded.

+*   Fix bug in Range comparisons when comparing to an excluded-end Range
+
+    Before:
+
+        (1..10).cover?(1...11) # => false
+
+    After:
+
+        (1..10).cover?(1...11) # => true
+
+    With the same change for `Range#include?` and `Range#===`.

+
+*   Use weak references in descendants tracker to allow anonymous subclasses to
+    be garbage collected.
+
+    *Edgars Beigarts*
+
+*   Update `ActiveSupport::Notifications::Instrumenter#instrument` to make
+    passing a block optional. This will let users use
+    `ActiveSupport::Notifications` messaging features outside of
+    instrumentation.

 *   Fix `Time#advance` to work with dates before 1001-03-07
 
     Before:
-    
+
         Time.utc(1001, 3, 6).advance(years: -1) # => 1000-03-05 00:00:00 UTC
-    
+
     After
-    
+
         Time.utc(1001, 3, 6).advance(years: -1) # => 1000-03-06 00:00:00 UTC
 
     Note that this doesn't affect `DateTime#advance` as that doesn't use a proleptic calendar.
