   - requests to [WMS](doc/endpoints.md#web-map-service) and [WFS](doc/endpoints.md#web-feature-service) endpoints
 - [#868](https://github.com/LayerManager/layman/issues/868) Responses to [GET Workspace Layer Metadata Comparison](doc/rest.md#get-workspace-layer-metadata-comparison) and [GET Workspace Map Metadata Comparison](doc/rest.md#get-workspace-map-metadata-comparison) do not respect [HTTP header `X-Forwarded-Prefix`](doc/client-proxy.md#x-forwarded-prefix-http-header) of the request intentionally, in order to keep URLs in canonical form.
 - [#868](https://github.com/LayerManager/layman/issues/868) Relations between map and [internal layers](doc/models.md#internal-map-layer) are updated in `map_layer` table when calling [POST Workspace Maps](doc/rest.md#post-workspace-maps), [PATCH Workspace Map](doc/rest.md#patch-workspace-map), [DELETE Workspace Map](doc/rest.md#delete-workspace-map), and [DELETE Workspace Maps](doc/rest.md#delete-workspace-maps).
+- [#927](https://github.com/LayerManager/layman/issues/927) Send styles to GeoServer with [`raw`](https://docs.geoserver.org/2.21.x/en/user/rest/api/styles.html#raw) param set to `True`.
 - [#880](https://github.com/LayerManager/layman/issues/880) Use Docker Compose v2 (`docker compose`) in Makefile without `compatibility` flag and remove `Makefile_docker-compose_v1` file. Docker containers are named according to Docker Compose v2 and may have different name after upgrade.
 - [#765](https://github.com/LayerManager/layman/issues/765) Stop saving OAuth2 claims in filesystem, use prime DB schema only.
 - [#893](https://github.com/LayerManager/layman/issues/893) It is possible to specify logging level by new environment variable [LAYMAN_LOGLEVEL](doc/env-settings.md#LAYMAN_LOGLEVEL). Default level is `INFO`.
