+### Known knowns
+
+- Relevant components and interfaces developed considering Gaia-X Trust Framework - 22.10\
+ Connection to an external Clearing House service for the entire Catena-X ecosystem is required. The Gaia-X compliance service should generally be capable of recognizing all companies that are able to register with the Catena-X Portal.
+- Conformity to [Asset Administration Shell v3.0](https://industrialdigitaltwin.org/wp-content/uploads/2023/04/IDTA-01002-3-0_SpecificationAssetAdministrationShell_Part2_API.pdf), [API live example](https://app.swaggerhub.com/apis/Plattform_i40/AssetAdministrationShellRegistryServiceSpecification/V3.0_SSP-001#/Asset%20Administration%20Shell%20Registry%20API/GetAssetAdministrationShellDescriptorById) (AAS) is given. For compatibility reasons, the deprecated DTR query interface “/query” will additionally be supported until Q1/2024. Details can be found in the [changelog](https://github.com/eclipse-tractusx/sldt-digital-twin-registry/blob/main/CHANGELOG.md) of the respective component.
+- EDC provides no new release compared to 23.09 but only patches: EDC version 0.5.3 is part of 23.12 with the following limitations:\
+ Standard Security Tests have been performed, but it is strongly recommended for each EDC operator to apply own security measures. Especially the Dynamic Application Security Testing (DAST) needs to be executed for each specific operation environment and instance.\
+ Tractus-X release guidelines (TRGs) 5.11, 7.01, 7.05 and 7.07 had not been fulfilled with v0.5.3. All of those are now addressed from [0.6.0-rc2](https://github.com/eclipse-tractusx/tractusx-edc/releases/tag/0.6.0-rc2) on.
+- MIW interim version 0.2.0 had passed functional E2E-testing within boundaries of the Catena-X consortia, but faced severe Security issues. MIW version 0.3.0 as part of the current Release package addresses all known Security issues, but did explicitly not undergo any functional E2E-testing (again).
+- FOSS components developed and pre-tested to TRL6 with artificial test data only
+- No crosscheck of functionality in verification environment
+- No execution of Load-, Performance- or Penetration Tests
+- No assignment of Export Control Classification Numbers (ECCN) to FOSS components
+- GeoBlocking recommended for Operations (GBaaS)
+- Security concept (overall) recommended for Operations
+
+
+### Runtime
+
+- Tested on [Kubernetes](https://en.wikipedia.org/wiki/Kubernetes) versions: `1.27.3`
+- Tested with [PostgreSQL](https://en.wikipedia.org/wiki/PostgreSQL) versions: `15`
