10878 new records added - 10773 CTV3 records (as part of the normal authoring cycle updates, exported from the termServer - this is the exact expected amount as it matches exactly the number of new concepts created in the latest authoring cycle) + 105 ICD-0 records (95 in Delta from mapping tool, so have emailed Donna to explain the 10 random inactivations on 23/5)

432470 records removed as part of the deprecation of the SNOMED CT RT Identifier refset - 900000000000498005 | SNOMED RT identifier simple map (foundation metadata concept) |. (including the circular reference to itself)

NB 1 record still related to this refset remains in the SimpleMap files, as agreed with the Release AG here: Deprecation of antecedent (old) SNOMED works

***** These 432470 changes do not appear in the Delta files, because the method we used for removal of the Refset was to create an updated version of the January 2017 International Edition, with the RT identifier Refset removed, so that when the SRS ran it automatically removed all 432470 records. We used this method to ensure that the RVF was comparing against the corrected version with the refset removed, and therefore didn't create 432470 false positives every time we ran the RVF.
