One of the biggest issues when updating to 1.1 is the fact that cmf_routing.dynamic.persistence.phpcr.route_basepath is no longer available.
cmf_routing.dynamic.persistence.phpcr.admin_basepath is only available when sonata admin is active and the new parameter cmf_routing.dynamic.persistence.phpcr.route_basepaths is not as convenient for the common case of just a single base path.
maybe we should therefore consider to reintroduce cmf_routing.dynamic.persistence.phpcr.route_basepath with the first path in the cmf_routing.dynamic.persistence.phpcr.route_basepaths array.
