Specific details for Studio 2019 SR2 API changes?

Hi,

  In an SDL blog entry about the new SR2 for Studio 2019, under "Changes to APIs in SDL Trados Studio 2019 SR2", Daniel Brockmann mentions a blog that describes the API changes, but the link is blank (I have checked in several language versions).

  Could we please have some specific details about the API changes introduced in SR2 (or a working link to this blog entry mentioned above)? The release notes do not mention the API at all.

Thanks,

Attila
