+- **Add a configuration setting for when to load custom CSS (initial work for
+ [dev/core#378](https://lab.civicrm.org/dev/core/issues/378):
+ [14876](https://github.com/civicrm/civicrm-core/pull/14876))**
+
+ A new function, `CRM_Utils_System::isFrontEndPage()`, indicates whether a page
+ is considered "front-end".
+
+- **Permit sort_name as a url parameter on advanced search
+ ([14475](https://github.com/civicrm/civicrm-core/pull/14475) and
+ [14920](https://github.com/civicrm/civicrm-core/pull/14920))**
+
+ You can now set `sort_name=x` in the URL on the advanced search form. In
+ doing this, the sort name field is now defined through metadata rather than
+ *ad hoc*.
+
+- **Menubar - Improve flexibility & remove hardcoded values
+ ([14924](https://github.com/civicrm/civicrm-core/pull/14924))**
+
+ The menu no longer relies on hardcoded pixel dimensions to determine mobile
+ appearance, and it replaces references to the ID selector `crm-container` with
+ the class selector of the same name (which is used more broadly).
+
+ This also resolves
+ [dev/core#1127](https://lab.civicrm.org/dev/core/issues/1127).
