 Minor Changes:
 
 * changed: Removed second regex pattern from Blob/contentType, File/contentType, File/value, Referable/idShort, Resource/path, and Resource/contentType attributes in the Part1-MetaModel-Schemas OpenAPI file. The first regex pattern is sufficient to cover all valid content types. While this is not directly fixing a bug, many downstream tools report issues, e.g. during code generation, when two regex patterns are defined for the same attribute. (https://github.com/admin-shell-io/aas-specs-api/issues/481[#481])
+* changed: Upgraded semanticIds of ProtocolInformation, SecurityAttributeObject, SecurityTypeEnum, and the items of the SecurityTypeEnum to V3.1 (https://github.com/admin-shell-io/aas-specs-api/issues/470[#470])
 * new: Add 404 'Not Found' to the PutSubmodelDescriptorByIdThroughSuperpath operation in the OpenAPI file for the AssetAdministrationShellRegistryServiceSpecification/SSP-001 profile.
