- The `format` keyword is no longer mandatory on ontology YML configuration files. When not present, OSP-core will try to guess the format from the file extension. If such guess fails though, it will still have to be provided.
- OSP-core now uses `rdflib >= 6.0.0, < 7.0.0` for users who have `python >= 3.7` installed. This translates to performance improvements in some cases, see [the benchmarks page](https://simphony.github.io/osp-core/dev/bench/index.html). For users who have `python < 3.7` installed, `rdflib==5.0.0` is still used, as the newer version requires `python >= 3.7`. This implies that at some point in the medium term, OSP-core's support for Python 3.6 will be dropped.
- Other minor changes (see the [full changelog](https://github.com/simphony/osp-core/compare/v3.5.7-beta...v3.5.8-beta)).
