Changelog¶

v1.14.0 2025.7¶

Improved internal biometric algorithm for better accuracy and performance.
Support for using VSS resources as input in enrollments and matchings operations. See the api definition for more details.
Improved batch enrollment validation to detect and reject invalid batch files during enrollment.

Internal improvements and bug fixes to enhance overall stability and performance.

Bug that caused the service to return 500 errors when the client provided an unsupported assurance method for the operation. Now the service responds with a 422 AssuranceMethodNotAcceptedError. See the api definition for more details.

Retrieve the sample of a credential: New endpoint GET /v1/accounts/{subject_id}/credentials/{credential_id}/sample to fetch the sample associated with a credential. See the api definition for more details.
Update credential tags: New endpoint PATCH /v1/accounts/{subject_id}/credentials/{credential_id}/tags to edit the tags associated with a credential. See the api definition for more details.

Support for stereo voice samples: New optional parameter sample_processing added to the enrollment and matching endpoints to indicate the sample processing to be used with the sample. See the api definition for more details.
New endpoint DELETE /v1/credentials: Allows you to delete credentials in batch from the system. See the api definition for more details.

Fixed issues:
- Deleted tags to remain associated with credentials.
- Typo in error message returned enrolling a subject with an existing subject id for that domain.
- Bug creating groups starting with a number.
- Bug enrolling a subject without specifying the subject id.

Credential listing endpoint: A new API endpoint (GET /v1/credentials) allows you to list credentials, with support for filtering by configuration (credential_configuration_urn) and tags.
See the api definition for more details.

Task deletion endpoint: You can now delete specific tasks via the new API endpoint (DELETE /v1/tasks/{task_id}).
See the api definition for more details.

Automatic task start timestamp: Tasks now automatically record their started_at time when they move to IN_PROGRESS. This timestamp is also included in the task report and in the response from GET /v1/tasks/{task_id}.
See the api definition for more details.

Fixed issues that caused:
- Tasks to remain pending or be duplicated.
- Empty accounts to be created after failed batch enrollments.

New assurance methods that ignore spoof detection:
- These new methods are named urn:vcsp:assurance_methods:enrollment:no_assurance:v1 and urn:vcsp:assurance_methods:matching:biometric_threshold:v1.
- The old methods urn:vcsp:assurance_methods:enrollment:thresholds:v1 and urn:vcsp:assurance_methods:matching:thresholds:v1 are marked as deprecated. They are still available but will be replaced by the new methods urn:vcsp:assurance_methods:enrollment:authenticity_threshold:v1 and urn:vcsp:assurance_methods:matching:biometric_and_authenticity_thresholds:v1 respectively in the 2025.5 release.

API updates:
- The endpoint /v1/groups/{group_name} now can respond asynchronously for group population and removal.
- New endpoint /v1/groups/{group_name}/clustering for clustering feature.
  
  Please refer to the API definition for more information about these changes.

Automatic Task Expiration: Task results now include an expire_at property. This ensures they are automatically removed after expiration, improving data management and system performance.
Enhanced Error Feedback: Introducing a new error response: InvalidServiceConfigurationError. This error helps identify and address issues caused by incorrect service configurations when interacting with the system. API reference documentation has been updated to include this error.

Consistent Response Structure: Removed valid_from and valid_until fields from matching responses to align with expected API outputs.
Data Integrity Improvements: Resolved an issue where deleted data could reappear unexpectedly. Collections are now properly flushed after deletion.

New GroupsLimitExceededError returned when a group creation request exceeds the maximum number of groups allowed for a tenant.
New SubjectsPerGroupLimitExceededError returned when a group population request exceeds the maximum number of subjects in a group allowed for a tenant.
New EnrollmentsLimitExceededError returned when an enrollment request exceeds the maximum number of enrollments allowed for a tenant.
New TagsLimitExceededError returned when a tag creation request exceeds the maximum number of tags allowed for a tenant.

Updated batch enrollment response to provide a report and a summary of the operation.
Endpoint /v1/groups/{group_name}/credentials to list credentials/subjects within a group.
Groups removal from the system when they expire.
Credentials expiration within groups.
Added response 503 if the system is temporarily out of service.

Regex to validate the subject identifier in the enrollment process.
PATCH request to /v1/groups/{group_name} endpoint to update an already existing group.
