fwiw, I ran oasdiff and it reported there are no non-backwards compatible breaking changes in the OpenAPI definition:

$ docker run --rm -t --mount type=bind,src=$PWD,dst=/data \
                 tufin/oasdiff breaking \
                 --format text \
                 /data/api/graphiant_api_docs_v26.6.0.json \
                 /data/api/graphiant_api_docs_v26.7.0.json

No breaking changes to report, but the specs are different.
Run 'oasdiff diff' to see structural differences.
