 Even though SSP 2.0 is a major version release, all SSP 1.0 conforming artifacts are considered to be fully conforming to SSP 2.0.
 SSP 2.0 conforming artifacts are only compliant to the SSP 1.0 standard if they use a 1.0 version number and only use features available in SSP 1.0.

+An overview of the changes in the 2.0.0 major release are provided in the bulleted lists below. Many different advancements to the specification have been discussed; however, the SSP 2.0 specification has, in its current status, been deduced as a feasible least-common denominator for the exchange of simulation packages that is able to provide value for both end-users and tool suppliers.
 
 * Support for FMI 3.0
   ** Support for the new basic data types: Float32/64, and [U]Int8/16/32/64.
-  ** Support for the new scheduled execution implementation kind in the component implementation attribute.
-  ** Support for clocks as a new connector kind, and clocked variables/connectors.
+  ** Support for the new scheduled execution implementation kind in the component implementation attribute. Scheduled execution enables, for example, enriched event controlled execution of SSP components.
+  ** Clocked signals were introduced to FMI 3.0 for more exactly control timing of events and evaluation of model partitions across FMUs. SSP 2.0 introduces clocks as a new connector kind, and clocked variables/connectors.
   ** Support for arrays in connectors and connections in the SSD, as well as in the SSV and SSB file formats.
   ** Support for structural parameters with the new connector kind `structuralParameter`.
   ** Support for the redesigned alias variable handling in FMI 3.0.

      This feature enables more advanced graphical editing of SSP models.
 * Traceability and meta-data features
   ** Integration of the `MetaData` element developed as part of the SSP Traceability layered standard into the core standard.
-     This allows the integration of arbitrary meta-data and digital signatures into the SSP file formats.
+     This allows the integration of arbitrary meta-data and digital signatures, such as life-cycle information, into the SSP file formats.
   ** Support for mixed content in annotations, as in FMI 3.0 and the SSP Traceability layered standard.
 * Support for Modelica
   ** Support in the core standard for Modelica models as components
