# 6.8.2

In this Version, the similarity calculation function between two biometric patterns has been improved. The generation of templateRaw has also been improved, with adjustments that reduce the number of errors when extracting patterns. In the rest-api service, it is now possible to configure the startup parameters through a file `config.json` and provide alternative paths for the information files generated by the SDK.

### Added

* The Rest-Api service accepts an external file `config.json` with the web server startup details.
* The Rest-Api service accepts a user path for `USAGE_PATH` and `DEBUG_PATH`.

### Improved

* `SelphIDFacialAuthenticationResult::GetSimilarity()` no longer saturates at the 1.0 end.
* The facial TemplateRaw reduces failures in pattern extraction.

### Corrected

* The rest api service in C++ limits the number of decimal places in JSON responses to 4.
