[keycloak-user] keycloak version change Custom SPI not backward compatible

Hi, We are facing issues while working with new version of keycloak. The jar we created using the old version of keycloak are not compatible with the new version. Some of the classes we extended to make custom spi's have been changes. For example: IdentityProviderBean KeycloakContext *Old version: 3.4.3* *New Version: 4.6.0* Does anyone has any idea as to why keycloak does not supports backward compatibility?. Thanks, Manisha
