minimalkb 2.1.0 - add `kb.label` to retrieve (multi-lingual) labels associated to a term - add support for querying direct classes, instances, subclasses, superclasses (via eg `kb.details`) - significantly simplify the event subscription mechanism. Now, you simply pass a list of patterns with an optional `one_shot` parameter (false by default) - better [API documentation](https://github.com/severin-lemaignan/minimalkb/blob/master/doc/api.md) - remove `kb.check` as it was strictly equivalent to `kb.exist` - fix bug where loaded ontologies would not be processed by the reasoner - fix internal methods being mistakenly exposed in the API - a few other minor bug fixes
