New in version 2

Although significant changes have been done for the 2nd version (a complete rewrite) the API is compatible with the 1.0.0 release. Except for the namespace which is now nlohmann::json_schema.

Version 2 supports JSON schema draft 7, whereas 1 was supporting draft 4 only. Please update your schemas.

The primary change in 2 is the way a schema is used. While in version 1 the schema was kept as a JSON-document and used again and again during validation, in version 2 the schema is parsed into compiled C++ objects which are then used during validation. There are surely still optimizations to be done, but validation speed has improved by factor 100 or more.
