Sidecar SDK

• Added: grantPromotionalEntitlementsGroup or granting a promotional entitlements group - all entitlements that are not already granted to a customer, need to be included in the request.
• Added: revokePromotionalEntitlementsGroup for revoking all of the entitlements of a group, unless they are a part of a different group.
• Added: unlinkPromotionalEntitlementsGroup for removing the references of the group from promotional entitlements that are a part of it, while keep granting access to those entitlements.

• Added: CancelSubscription.awaitSubscriptionCancellation for controlling whether to wait for confirmation from billing solutions that are integrated with Stigg before marking subscription as canceled in Stigg

• Added: getEntitlement method - a unified way to check any type of feature entitlement (boolean, numeric, or metered) that automatically returns the appropriate entitlement type based on the feature configuration

• Added: AccessDeniedReason.Revoked for determining when an entitlement has been explicitly revoked.

​

Migration steps

1. Upgrade the Sidecar image to version 2.498.0 or later. The new non-TLS port is set using the GRPC_PORT environment variable (default: 80). For backwards compatibility, legacy TLS is still supported and can be configured with the PORT environment variable (default: 8443).
2. Upgrade the Sidecar SDK to version 3.0.0 or later and send requests to the new non-TLS port (same as GRPC_PORT). This applies to all SDK programming languages.

Backwards compatibility with older Sidecar image versions

stigg = Stigg(ApiConfig(api_key=api_key), remote_sidecar_use_legacy_tls=True)

• Added: Support for local evaluation of static entitlements in the Java SDK.
  Applications can now evaluate entitlements offline using a static config, without requiring real-time API calls to the Sidecar service.
  This is especially useful for air-gapped, on-premise, or secure environments.

• Changed: The health and metrics endpoints are now exposed over HTTP by default on port 8080, instead of HTTPS with a self-signed certificate.
• Added: You can configure the health and metrics port using the METRICS_PORT environment variable.

• Improved: The Sidecar no longer crashes on startup when encountering initialization issues such as an invalid API key or unreachable Stigg API. It now starts in fallback mode and serves entitlements from Redis or fallback values.
• Added: /metrics endpoint exposing service-level and Sidecar-specific metrics in Prometheus format, including:
  • sidecar_initialization_errors_total
  • sidecar_invalid_api_key_errors_total
  • sidecar_network_request_errors_total
  • sidecar_redis_client_errors_total
  • sidecar_cache_hits_total
  • sidecar_cache_misses_total

• Added: offline mode

• Added: Edge support for getActiveSubscriptionsList

• Fixed: when access to entitlement was denied due to the reaching of a budget cap, getMeteredEntitlements returned AccessDeniedReason.UNSPECIFIED instead of AccessDeniedReason.BudgetExceeded.

• Added: ability to more easily determine the usage period of metered entitlements using:
  • Entitlement.usagePeriodStart
  • Entitlement.usagePeriodEnd

• Added: ability to set sidecar log level using env var (default: INFO)

• Added: ability to configure the “health” and “ready” endpoints by passing HEALTH_ENDPOINT_URL and READY_ENDPOINT_URL environment variables
