 ## [unreleased]
+### Added
+- take into account tunnel categories B, C, D, and E when restricting roads for the transport of dangerous goods via the `hazmat` flag in vehicle parameters ([#1879](https://github.com/GIScience/openrouteservice/pull/1879))
 ### Changed
 - update docs dependency: VitePress ([#1872](https://github.com/GIScience/openrouteservice/pull/1872))
 - adjust documentation for export endpoint ([#1872](https://github.com/GIScience/openrouteservice/pull/1872))
-
 ### Fixed
 - do not enforce a time-dependent routing algorithm unless the weighting requires it ([#1865](https://github.com/GIScience/openrouteservice/pull/1865))
 - failing queries that combined departure/arrival parameters with avoid polygons ([#1871](https://github.com/GIScience/openrouteservice/pull/1871))
