Notes for this Release:

1. New vaccine concepts to support the ongoing work for Immunization.
2. Release notes for International releases including the International Edition and the Common French extension are no longer included in the Canadian Edition release package. International release notes can be accessed here and Common French release notes can be accessed here.
3. Inclusion of concepts that originated in other national extensions and were promoted to core because they also meet Canadian requirements and, as such, meet the international use case (lateral promotion).
4. Two (2) new subsets were created to support the new National Vaccine Catalogue (NVC).
5. In line with the new implementation of Annotations, two new refsets have been added to the International Edition Release package, from December 2023 onwards:
   der2_scsRefset_ComponentAnnotationStringValueSnapshot_INT_20240101.txt
   der2_sscsRefset_MemberAnnotationStringValueSnapshot_INT_20240101.txt
   These refset files are empty for the February 2024 release, whilst content is authored in future editing cycles. However, they will then be populated with Annotations data from one of the future 2024 International Edition releases onwards (date to be confirmed). These improvements were introduced in the December 2023 International Edition release, and will be used in all future International Edition releases until further notice.
6. French translation to support Canadian implementations, including: ongoing immunization work;
7. To enable improvements to the quality and analytics capabilities of SNOMED CT, SNOMED International has enhanced the underlining logic profile of the terminology. The changes are now using the Web Ontology Language (OWL) for expressing the concept definitions  These expressions are published as an RF2 compliant reference set, replacing the stated relationships file. The stated relationships file have been deprecated in this release of the CA Edition, as they were deprecated in the July 2019 International release. 
8. All previous stated relationships have been inactivated since that way of distributing the authoring assertions have been replaced by the OWL refset axioms. This means that all previously active concepts now have their concept definitions expressed in the new format. 
9. If this is impacting your local extension because it is depending on the stated form of the Canadian release, and you need support to migrate to the new formalism, please contact us at [email protected]. 
For further information, please refer to SNOMED International Edition Complete OWL file DEMONSTRATION Release Notes for July 2019.
