 What's new in Django 5.1
 ========================
 
+``{% query_string %}`` template tag
+-----------------------------------
+
+Django 5.1 introduces the :ttag:`{% query_string %} <query_string>` template
+tag, simplifying the modification of query parameters in URLs, making it easier
+to generate links that maintain existing query parameters while adding or
+changing specific ones.
+
+For instance, navigating pagination and query strings in templates can be
+cumbersome. Consider this template fragment that dynamically generates a URL
+for navigating to the next page within a paginated view:
+
+.. code-block:: html+django
+
+    {# Linebreaks added for readability, this should be one, long line. #}
+    <a href="?{% for key, values in request.GET.iterlists %}
+      {% if key != "page" %}
+        {% for value in values %}
+          {{ key }}={{ value }}&amp;
+        {% endfor %}
+      {% endif %}
+    {% endfor %}page={{ page.next_page_number }}">Next page</a>
+
+When switching to using this new template tag, the above magically becomes:
+
+.. code-block:: html+django
+
+    <a href="{% query_string page=page.next_page_number %}">Next page</a>
+
+PostgreSQL Connection Pools
+---------------------------
+
+Django 5.1 also introduces :ref:`connection pool <postgresql-pool>` support for
+PostgreSQL. As the time to establish a new connection can be relatively long,
+keeping connections open can reduce latency.
+
+To use a connection pool with `psycopg`_, you can set the ``"pool"`` option
+inside :setting:`OPTIONS` to be a dict to be passed to
+:class:`~psycopg:psycopg_pool.ConnectionPool`, or to ``True`` to use the
+``ConnectionPool`` defaults::
+
+    DATABASES = {
+        "default": {
+            "ENGINE": "django.db.backends.postgresql",
+            # ...
+            "OPTIONS": {
+                "pool": {
+                    "min_size": 2,
+                    "max_size": 4,
+                    "timeout": 10,
+                }
+            },
+        },
+    }
