# 6.17.0

This Version enables future-date validation of templateRaw through the method `GetValidTimeStamp()`. It also implements timestamps in 1:N gallery items. This allows previous biometric patterns to be listed or removed before a specified time interval. Lastly, a bug affecting gallery consistency when using the method `SelphIDIdentifier::RemoveWithTemplateID()`.

### Added

* `SelphIDVerifierOptions::Get/SetFutureTimeAllowed()` to allow future-dated tokens not to be rejected.
* Environment variable `FACEPHI_SELPHID_FUTURE_TIME_ALLOWED` to set a global value for `FutureTimeAllowed`.
* `futureAllowedSeconds` in the `options` of the C++ rest-api service.
* `SelphIDIdentifier::ListObsoleteGalleryTemplateIDs()` to list gallery items older than a time interval.
* `SelphIDIdentifier::RemoveObsoleteGalleryTemplateIDs()` to delete gallery items older than a time interval.
* GET Endpoint `/identify/obsolete/{galleryId}/{intervalSeconds}` in the C++ rest-api service.
* DELETE Endpoint `/identify/obsolete/{galleryId}/{intervalSeconds}` in the C++ rest-api service.

### Fixed

* Problem in `SelphIDIdentifier::RemoveWithTemplateID()` that left the gallery state inconsistent.
