Version 3.1.0

❗ IMPORTANT Update ❗

The zone_uuid claim in Identity service tokens has been deprecated and is now replaced by the app_tid claim. You should use the app_tid claim to identify the unique tenant id, which was previously referred to as the zone.

• [java-api]
  • Token interface is extended with default method getAppTid() and getZoneId() method has been deprecated, use getAppTid() method instead ⚠️ This is also relevant for Xsuaa applications not only Identity based applications
  • TokenClaims is extended with the SAP_GLOBAL_APP_TID and SAP_GLOBAL_ZONE_ID is deprecated
• [token-client]
  • OAuth2TokenKeyService interface has been extended with retrieveTokenKeys(@Nonnull URI tokenKeysEndpointUri, @Nullable String tenantId, @Nullable String clientId) method
  • HttpHeaders constants are extended with X-app_tid and X-client_id headers
  • JWKs fetch from identity service going forward requires mandatory headers: X-app_tid abd X-client_id this has been updated in the default implementations of the OAuth2TokenKeyService:
    • DefaultOAuth2TokenKeyService
    • OAuth2TokenKeyServiceWithCache (java-security module)
    • SpringOAuth2TokenKeyService
• [java-security] AbstractToken is serializable fixes #1209
• [java-security-test] JwtGenerator adds app_tid claims with the default value the-app-tid to the Identity tokens. ❗Some adaption might be required when calling the getZoneId() method as it will return now the app_tid value back when default values are used.

Dependency upgrades

• Bump spring.core.version from 6.0.9 to 6.0.11
• Bump spring.boot.version from 3.0.6 to 3.1.2

Version 3.0.1

[spring-xsuaa]

Dependency upgrades

• Bump spring.core.version from 6.0.8 to 6.0.9
• Bump reactor-core from 3.5.5 to 3.5.6
• Bump btp-environment-variable-access from 0.5.2 to 0.6.0

Version 3.0.0

Baseline changes

cloud-security-services-integration-library requires

• Java 17
• Spring Boot 3.0.x
• Spring security 6.0.x

Breaking Changes

• Identity service configurations need to provide domains via String array in JSON key 'identity.credentials.domains'. Providing String values under key 'identity.credentials.domain' is not supported anymore. IAS configurations from service bindings have been generated like this for a long time already. This should only affect old configuration files manually written for testing.
