 * The [`Marten::Handlers::RecordDetail`](../../handlers-and-http/reference/generic-handlers.md#displaying-a-record), [`Marten::Handlers::RecordUpdate`](../../handlers-and-http/reference/generic-handlers.md#updating-a-record), and [`Marten::Handlers::RecordDelete`](../../handlers-and-http/reference/generic-handlers.md#deleting-a-record) generic handlers now provide the ability to specify a custom [query set](../../models-and-databases/queries.md) instead of a model class. This can be achieved through the use of the [`#queryset`](pathname:///api/dev/Marten/Handlers/RecordRetrieving.html#queryset(queryset)-macro) macro.
 * A new middleware was introduced to make it easy to override the method of incoming requests based on the value of a specific request parameter or header: the [method override middleware](../../handlers-and-http/reference/middlewares.md#method-override-middleware). This mechanism is useful for overriding HTTP methods in HTML forms that natively support GET and POST methods only. A dedicated set of [settings](../../development/reference/settings.md#method-overriding-settings) is also available to easily customize the behavior of this middleware.
 * The value of the max-age directive used for the Cache-Control header that is set by the [assets serving middleware](../../handlers-and-http/reference/middlewares.md#asset-serving-middleware) can now be configured in the [`assets.max_age`](../../development/reference/settings.md#max_age) setting.
+* Subclasses of the [`Marten::Handlers::Template`](../../handlers-and-http/reference/generic-handlers.md#rendering-a-template) generic handler now support a [`#content_type`](pathname:///api/dev/Marten/Handlers/Rendering/ClassMethods.html#content_type(content_type%3AString|Nil)-instance-method) class method that allows configuring the content type of the response (unless specified, the content type will default to `text/html`).
