135 new records added, plus

6688 active records removed (including 6708 inactivated), as expected as a result of the automatic reversion of the issue from Sept 2018 (SNOMED CT Managed Service - Belgium Extension Critical Incident Response Plan - March 2019), in which 6708 inferred relationships were incorrectly added (and therefore correctly inactivated in this release), and 2736 inferred relationships were incorrectly inactivated.

Obviously the 2736 records that were incorrectly inactivated in the last release do not match the 135 records that were added back into this release! However, both Kai and Yong confirmed that this is the expected result, due to a mathematical coincidence in this release cycle, whereby nearly all of those records (2601 of them) just happened to get inactivated in the latest Jan 2019 International Edition! See Yong's email from 09:02 on 26/2/2019:

I checked the inactivated inferred relationships. 1,934 product concepts have been classified to more accurate parent concepts. Therefore, we see a large number of inactivation of the IS A relationships. I randomly checked some and they are correct inactivations.

The rest results of inactivation of concepts in either sourceId or destinationId or both. These inactivations involved different hierarchies, e.g. findings,

procedures etc.

So, the good news is that all of these are expected inactivations in the inferred relationships. 

Plus Kai's email from 21:52 on 25/2/2019:

Attached is a zip of the 2,601 inactive inferred relationships from the Jan 2019 International release which match the active, source, destination and group of the relationships mistakenly made inactive in the Sept 2018 Belgian release.

This explains why we only have 135 active relationships when we classify the March 2019 Belgian release.
