 ### Changes
 - [#257](https://github.com/jirik/layman/issues/257) Endpoints [GET Layers](doc/rest.md#get-layers) and [GET Maps](doc/rest.md#get-maps) can filter and reorder results according to new query parameters.
 - [#257](https://github.com/jirik/layman/issues/257) Responses of [GET Layers](doc/rest.md#get-layers), [GET Workspace Layers](doc/rest.md#get-workspace-layer), [GET Workspace Layer](doc/rest.md#get-workspace-layer), [PATCH Workspace Layer](doc/rest.md#patch-workspace-layer), [GET Maps](doc/rest.md#get-maps), [GET Workspace Maps](doc/rest.md#get-workspace-map), [GET Workspace Map](doc/rest.md#get-workspace-map), and [PATCH Workspace Map](doc/rest.md#patch-workspace-map) contains new attribute `updated_at` with date and time of last PATCH/POST request to given publication.
+- [#302](https://github.com/jirik/layman/issues/302) Metadata properties [wms_url](doc/metadata.md#wms_url) and [wfs_url](doc/metadata.md#wfs_url) contain new URL parameter `LAYERS` whose value is name of the layer. It's non-standard way how to store name of the layer at given WMS/WFS instance within metadata record.
