+*   Add newline between each migration in `structure.sql`.
+
+    Keeps schema migration inserts as a single commit, but allows for easier
+    git diffing.
+
+    Fixes #25504.
+

+
+*   The flag `error_on_ignored_order_or_limit` has been deprecated in favor of
+    the current `error_on_ignored_order`.
+
+    *Xavier Noria*
+
+*   Batch processing methods support `limit`:
+
+        Post.limit(10_000).find_each do |post|
+          # ...
+        end
+
+    It also works in `find_in_batches` and `in_batches`.
+
+    *Xavier Noria*
+
+*   Using `group` with an attribute that has a custom type will properly cast
+    the hash keys after calling a calculation method like `count`. Fixes #25595.
+
+    *Sean Griffin*
+
+*   Fix the generated `#to_param` method to use `omission: ''` so that
+    the resulting output is actually up to 20 characters, not
+    effectively 17 to leave room for the default "...".
+    Also call `#parameterize` before `#truncate` and make the
+    `separator: /-/` to maximize the information included in the
+    output.
+
+    Fixes #23635.
+
+    *Rob Biedenharn*
+
+*   Ensure concurrent invocations of the connection reaper cannot allocate the
+    same connection to two threads.
+
+    Fixes #25585.
+
+    *Matthew Draper*
+
 *   Inspecting an object with an associated array of over 10 elements no longer
     truncates the array, preventing `inspect` from looping infinitely in some
     cases.
