# Which Problems Are Solved
The current maintained gRPC server in combination with a REST (grpc)
gateway is getting harder and harder to maintain. Additionally, there
have been and still are issues with supporting / displaying `oneOf`s
correctly.
We therefore decided to exchange the server implementation to
connectRPC, which apart from supporting connect as protocol, also also
"standard" gRCP clients as well as HTTP/1.1 / rest like clients, e.g.
curl directly call the server without any additional gateway.
# How the Problems Are Solved
- All v2 services are moved to connectRPC implementation. (v1 services
are still served as pure grpc servers)
- All gRPC server interceptors were migrated / copied to a corresponding
connectRPC interceptor.
- API.ListGrpcServices and API. ListGrpcMethods were changed to include
the connect services and endpoints.
- gRPC server reflection was changed to a `StaticReflector` using the
`ListGrpcServices` list.
- The `grpc.Server` interfaces was split into different combinations to
be able to handle the different cases (grpc server and prefixed gateway,
connect server with grpc gateway, connect server only, ...)
- Docs of services serving connectRPC only with no additional gateway
(instance, webkey, project, app, org v2 beta) are changed to expose that
- since the plugin is not yet available on buf, we download it using
`postinstall` hook of the docs
# Additional Changes
- WebKey service is added as v2 service (in addition to the current
v2beta)

# Which Problems Are Solved
When using implicit flow through the session API and a login UI on a
custom domain (proxy), the tokens were signed by the API domain of the
instance, rather than the public (proxy) domain.
The SAML response had the same issue. Additionally, the saml library had
an issue and lost the issuer context. This prevented also a successful
login through the hosted login UI.
# How the Problems Are Solved
- The issuer of the SAML and Auth request is persisted to provide the
information when signing the responses and tokens.
- The SAML library is updated to the latest version.
# Additional Changes
None
# Additional Context
None
# Which Problems Are Solved
Through configuration on projects, there can be additional permission
checks enabled through an OIDC or SAML flow, which were not included in
the OIDC and SAML services.
# How the Problems Are Solved
Add permission check through the query-side of Zitadel in a singular SQL
query, when an OIDC or SAML flow should be linked to a SSO session. That
way it is eventual consistent, but will not impact the performance on
the eventstore. The permission check is defined in the API, which
provides the necessary function to the command side.
# Additional Changes
Added integration tests for the permission check on OIDC and SAML
service for every combination.
Corrected session list integration test, to content checks without
ordering.
Corrected get auth and saml request integration tests, to check for
timestamp of creation, not start of test.
# Additional Context
Closes#9265

# Which Problems Are Solved
It is currently not possible to use SAML with the Session API.
# How the Problems Are Solved
Add SAML service, to get and resolve SAML requests.
Add SAML session and SAML request aggregate, which can be linked to the
Session to get back a SAMLResponse from the API directly.
# Additional Changes
Update of dependency zitadel/saml to provide all functionality for
handling of SAML requests and responses.
# Additional Context
Closes#6053
