 - Users with :ref:`store-query <actions_store_query>` and :ref:`execute-sql <actions_execute_sql>` permission can create stored queries from the SQL query page or the new ``GET /<database>/-/queries/store`` form. (:issue:`2735`)
 - The database page now shows a count and preview of stored queries, capped at five, and links to new paginated query browsers at ``/-/queries`` and ``/<database>/-/queries``. Those browsers support search. (:issue:`2735`)
 - Stored queries created by users default to private and untrusted. Private stored queries can only be viewed, updated or deleted by their owner, even if another actor has broad ``view-query``, ``update-query`` or ``delete-query`` permission. Untrusted stored queries execute using the permissions of the actor running them. See :ref:`stored_queries` and :ref:`trusted_stored_queries` for details. (:issue:`2735`)
+- Configured queries from ``datasette.yaml`` are trusted by default, so they can execute with ``view-query`` permission alone. They can opt out of that behavior using ``is_trusted: false`` but cannot be made private; private queries are only available for user-created stored queries. (:issue:`2735`)
 - New ``store-query``, ``update-query`` and ``delete-query`` permissions, plus updated semantics for :ref:`view-query <actions_view_query>`. Trusted stored queries can still execute with ``view-query`` alone; untrusted read queries also require :ref:`execute-sql <actions_execute_sql>` and untrusted writable queries require :ref:`execute-write-sql <actions_execute_write_sql>` plus the relevant table-level write permissions.

 Write SQL UI
 ~~~~~~~~~~~~
 
-- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted and links to a newly inserted row when a single-row insert succeeds. (:issue:`2742`)
+- New "Write to this database" interface at ``/<database>/-/execute-write`` for running arbitrary writable SQL against mutable databases. The form extracts named parameters, analyzes the SQL, shows the table operations that will be attempted, includes starter templates for ``INSERT``, ``UPDATE`` and ``DELETE`` statements and links to a newly inserted row when a single-row insert succeeds. This is also available as a :ref:`JSON API <ExecuteWriteView>`. (:issue:`2742`)
 - Added the new :ref:`execute-write-sql <actions_execute_write_sql>` permission for running arbitrary writable SQL. Execution is also gated by table-level permissions such as :ref:`insert-row <actions_insert_row>`, :ref:`update-row <actions_update_row>` and :ref:`delete-row <actions_delete_row>`, and writes to attached databases are rejected. (:issue:`2742`)
 - The write SQL analyzer now uses a deny-by-default model for unsupported operations. Reads from source tables require :ref:`view-table <actions_view_table>` permission, schema changes require :ref:`create-table <actions_create_table>`, :ref:`alter-table <actions_alter_table>` or :ref:`drop-table <actions_drop_table>` as appropriate, and row mutation statements require the full ``insert-row``, ``update-row`` and ``delete-row`` permission set. SQL functions are allowed and are not separately permission-gated. (:issue:`2748`)
 - User-supplied write SQL now rejects ``VACUUM`` and writes to SQLite virtual tables or shadow tables. These restrictions also apply to untrusted stored write queries; trusted configured stored queries continue to skip these filters. (:issue:`2748`)

 Datasette analyzes the SQL before executing it. The actor must have ``execute-write-sql`` permission for the database, and must also have any permissions required by the operations in the SQL. For example, inserts and updates against a table require ``insert-row``, ``update-row`` and ``delete-row`` permissions for that table. Reads performed as part of the write, such as ``insert into dogs select ... from other_table``, require ``view-table`` permission on the source table. Schema changes require ``create-table``, ``alter-table`` or ``drop-table`` permissions as appropriate.
