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

[Manisha Nandal]

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
