dxflib ABI changed yet nothing changed

Hi, Got via e-mail that libdxflib's ABI changed in comparison to previous release, yet nothing changed in the package except version bump for the mass rebuild. Why is that? Digest Summary: 1. dist.abicheck FAILED for libdxflib-3.17.0-8.fc30 2. dist.abicheck FAILED for libdxflib-3.17.0-8.fc30 ------------------------------------------------------------------------------- (2019-02-04 05:48:12 UTC) dist.abicheck FAILED for libdxflib-3.17.0-8.fc30 - https://taskotron.fedoraproject.org/artifacts/all/f7d968de-26bc-11e9-a292... dist.abicheck FAILED for libdxflib-3.17.0-8.fc30 ------------------------------------------------------------------------------- (2019-02-04 05:48:16 UTC) dist.abicheck FAILED for libdxflib-3.17.0-8.fc30 - https://taskotron.fedoraproject.org/artifacts/all/f7c055d8-26bc-11e9-9451... dist.abicheck FAILED for libdxflib-3.17.0-8.fc30
