+*   Add `compact_blank` for those times when you want to remove #blank? values from
+    an Enumerable (also `compact_blank!` on Hash, Array, ActionController::Parameters)
+
+    *Dana Sherson*
+
+*   Make ActiveSupport::Logger Fiber-safe. Fixes #36752.
+
+    Use `Fiber.current.__id__` in `ActiveSupport::Logger#local_level=` in order
+    to make log level local to Ruby Fibers in addition to Threads.
+
+    Example:
+
+        logger = ActiveSupport::Logger.new(STDOUT)
+        logger.level = 1
+        p "Main is debug? #{logger.debug?}"
+
+        Fiber.new {
+          logger.local_level = 0
+          p "Thread is debug? #{logger.debug?}"
+        }.resume
+
+        p "Main is debug? #{logger.debug?}"
+
+    Before:
+
+        Main is debug? false
+        Thread is debug? true
+        Main is debug? true
+
+    After:
+
+        Main is debug? false
+        Thread is debug? true
+        Main is debug? false
+
+    *Alexander Varnin*
+
+*   Allow the `on_rotation` proc used when decrypting/verifying a message to be
+    passed at the constructor level.
+
+    Before:
+
+        crypt = ActiveSupport::MessageEncryptor.new('long_secret')
+        crypt.decrypt_and_verify(encrypted_message, on_rotation: proc { ... })
+        crypt.decrypt_and_verify(another_encrypted_message, on_rotation: proc { ... })
+
+    After:
+
+        crypt = ActiveSupport::MessageEncryptor.new('long_secret', on_rotation: proc { ... })
+        crypt.decrypt_and_verify(encrypted_message)
+        crypt.decrypt_and_verify(another_encrypted_message)

+    *Edouard Chin*
+
+*   `delegate_missing_to` would raise a `DelegationError` if the object
+    delegated to was `nil`. Now the `allow_nil` option has been added to enable
+    the user to specify they want `nil` returned in this case.
+
+    *Matthew Tanous*
+
 *   `truncate` would return the original string if it was too short to be truncated
     and a frozen string if it were long enough to be truncated. Now truncate will
     consistently return an unfrozen string regardless. This behavior is consistent
