# Which Problems Are Solved
In the "new" structured logging, request details were added in different
middlewares, such as request, instance and user IDs. This meant the the
upstream request logging middleware did not have access to metadata that
got added later, resulting in incomplete logs. Furthermore it was not
possible to correlate an API error response to log output.
# How the Problems Are Solved
A mutable request details object is added to the context early on. When
the api authz function run, the instance and user IDs are added to this
object as they become available. Every logline emitted after this
(time-wise) will then all contain these details under the `request` log
group.

</details>
Request IDs are now also returned with a response header or metadata.
Depending on the protocol:
- HTTP calls always return the request ID as header, regardless of
status
- gRPC calls always return the request ID as header, even if there was
an error
- connect RPC calls returns the request ID as header on success, trailer
in case of error. This is because header must be set on the response
object, which is nil in case of error. When there is an error, metadata
can be added which are then sent as trailers.
# Additional Changes
- Use the existing call duration middleware for both request ID and
logging for a consistent request start timestamp in all layers.
- Upgrade sloggcp for some fixes (notably TraceID)
- Modify the NoCache middleware so it uses `SetHeaders` instead of
`SendHeaders`. The latter prevented any other handler from setting
headers, including the new request ID middleware.

# Which Problems Are Solved
There were still some emails (passkey registration and domain claimed)
sent with links pointing to login v1 even when the login v2 was enabled
for the instance.
Also while looking into the issue, it was discovered that some links
pointing to login V2 were not correctly generated.
# How the Problems Are Solved
- Added default paths for passkey registration and domain claimed
notifications
- Fixed the existing paths to properly handle concatenation (resp. use
`url.ResolveReference`)
- Change their go types (from string) to `*url.URL`
- Added a mapstructure hook for string to url
- Removed unnecessary `InstanceSetupFeatures` and corresponding
conversions
- Refactored the methods on the `login.DefaultPaths` struct and added an
interface to the `Commands` to only need to pass a single config (and
not every method)
- Added an `OriginURL` method to the `DomainCtx` to prevent going from
url to string and back
- Added the use of the templates in case of enabled login v2 for passkey
registration and domain claimed)

# Which Problems Are Solved
Zitadel did not provide easy correlation between errors, logs, traces
and metrics. The configuration for those instrumentations was also not
consistent, with some supporting different exporters then others.
Implementation and parsing of config was also spaghettified over
multiple packages, with awkward parsing and inconsistent naming of
options.
# How the Problems Are Solved
All telemetry is now merged under the name "instrumentation". Why?
1. We thought it was a good idea in the past to call the milestone
exporter `Telemtry` in the runtime config. Calling this `TelemetryV2`
looks weird.
2. Not everything is a meter and not everything is sent (tele...).
3. It's also
[defined](https://opentelemetry.io/docs/concepts/instrumentation/) as
such by the OTEL documentation.
## New features
- Adds structured, context based logging with trace-ID awareness
- Static log fields are added to the context, such as service and
request path
- Static log fields are injected in each logline emitted by the
application
- Structured logs can also be send to an otel exporter
- Structured logs can be printed to StdErr in text and JSON format
- Error sinks make sure every error is logged at the correct level:
- Warnings for client side errors (HTTP 400 range, Invalid request etc)
- Error for server side errors (Internal server errors)
- Metrics can now also be send to a OTEL collector. (previously they
could only be scraped from `/debug/metrics` with prometheus)
## Exporters
This change adds all the exporters supported by OTEL upstream and some
google specific exporters for our cloud deployment.
- StdOut / StdErr: all instrumentations
- OTEL gRPC / HTTP: all instrumentations
- Google: all instrumentations except logging
- Prometheus (pull-based): only metrics
The exception is profiling, which only supports the google exporting due
to lack of support by OTEL upstream.
## Configuration and structure
- All instrumentation is moved into the new `backend/v3/instrumentation`
package. It reuses configuration types, so both code and runtime
configuration are easier to understand.
- The `internal/telemetry` packages are removed.
- Instrumentation is started with a single function and a proper
shutdown function is now provided.
- Legacy configuration is still parsed from the runtime config, as long
as the new configuration is disabled. This allows backporting this
feature to v4 without breaking existing configurations.
# Additional Changes
- Devcontainer: set `$PATH` variable so installed go binaries can be run
individually, without NX.
- NX: install GCI tool to fix imports
# Additional Context

# Which Problems Are Solved
When an organization domain is verified, e.g. also when creating a new
organization (incl. generated domain), existing usernames are checked if
the domain has been claimed.
The query was not optimized for instances with many users and
organizations.
# How the Problems Are Solved
- Replace the query, which was searching over the users projection with
(computed loginnames) with a dedicated query checking the loginnames
projection directly.
- All occurrences have been updated to use the new query.
# Additional Changes
None
# Additional Context
- reported through support
- requires backport to v3.x
# Which Problems Are Solved
Currently if a user signs in using an IdP, once they sign out of
Zitadel, the corresponding IdP session is not terminated. This can be
the desired behavior. In some cases, e.g. when using a shared computer
it results in a potential security risk, since a follower user might be
able to sign in as the previous using the still open IdP session.
# How the Problems Are Solved
- Admins can enabled a federated logout option on SAML IdPs through the
Admin and Management APIs.
- During the termination of a login V1 session using OIDC end_session
endpoint, Zitadel will check if an IdP was used to authenticate that
session.
- In case there was a SAML IdP used with Federated Logout enabled, it
will intercept the logout process, store the information into the shared
cache and redirect to the federated logout endpoint in the V1 login.
- The V1 login federated logout endpoint checks every request on an
existing cache entry. On success it will create a SAML logout request
for the used IdP and either redirect or POST to the configured SLO
endpoint. The cache entry is updated with a `redirected` state.
- A SLO endpoint is added to the `/idp` handlers, which will handle the
SAML logout responses. At the moment it will check again for an existing
federated logout entry (with state `redirected`) in the cache. On
success, the user is redirected to the initially provided
`post_logout_redirect_uri` from the end_session request.

# Which Problems Are Solved
Classic permission checks execute for every returned row on resource
based search APIs. Complete background and problem definition can be
found here: https://github.com/zitadel/zitadel/issues/9188
# How the Problems Are Solved
- PermissionClause function now support dynamic query building, so it
supports multiple cases.
- PermissionClause is applied to all list resources which support org
level permissions.
- Wrap permission logic into wrapper functions so we keep the business
logic clean.
# Additional Changes
- Handle org ID optimization in the query package, so it is reusable for
all resources, instead of extracting the filter in the API.
- Cleanup and test system user conversion in the authz package. (context
middleware)
- Fix: `core_integration_db_up` make recipe was missing the postgres
service.

# Which Problems Are Solved
Some IdP callbacks use HTTP form POST to return their data on callbacks.
For handling CSRF in the login after such calls, a 302 Found to the
corresponding non form callback (in ZITADEL) is sent. Depending on the
size of the initial form body, this could lead to ZITADEL terminating
the connection, resulting in the user not getting a response or an
intermediate proxy to return them an HTTP 502.
# How the Problems Are Solved
- the form body is parsed and stored into the ZITADEL cache (using the
configured database by default)
- the redirect (302 Found) is performed with the request id
- the callback retrieves the data from the cache instead of the query
parameters (will fallback to latter to handle open uncached requests)
# Additional Changes
- fixed a typo in the default (cache) configuration: `LastUsage` ->
`LastUseAge`
# Additional Context
- reported by a customer
- needs to be backported to current cloud version (2.66.x)

# Which Problems Are Solved
ZITADEL currently selects the instance context based on a HTTP header
(see https://github.com/zitadel/zitadel/issues/8279#issue-2399959845 and
checks it against the list of instance domains. Let's call it instance
or API domain.
For any context based URL (e.g. OAuth, OIDC, SAML endpoints, links in
emails, ...) the requested domain (instance domain) will be used. Let's
call it the public domain.
In cases of proxied setups, all exposed domains (public domains) require
the domain to be managed as instance domain.
This can either be done using the "ExternalDomain" in the runtime config
or via system API, which requires a validation through CustomerPortal on
zitadel.cloud.
# How the Problems Are Solved
- Two new headers / header list are added:
- `InstanceHostHeaders`: an ordered list (first sent wins), which will
be used to match the instance.
(For backward compatibility: the `HTTP1HostHeader`, `HTTP2HostHeader`
and `forwarded`, `x-forwarded-for`, `x-forwarded-host` are checked
afterwards as well)
- `PublicHostHeaders`: an ordered list (first sent wins), which will be
used as public host / domain. This will be checked against a list of
trusted domains on the instance.
- The middleware intercepts all requests to the API and passes a
`DomainCtx` object with the hosts and protocol into the context
(previously only a computed `origin` was passed)
- HTTP / GRPC server do not longer try to match the headers to instances
themself, but use the passed `http.DomainContext` in their interceptors.
- The `RequestedHost` and `RequestedDomain` from authz.Instance are
removed in favor of the `http.DomainContext`
- When authenticating to or signing out from Console UI, the current
`http.DomainContext(ctx).Origin` (already checked by instance
interceptor for validity) is used to compute and dynamically add a
`redirect_uri` and `post_logout_redirect_uri`.
- Gateway passes all configured host headers (previously only did
`x-zitadel-*`)
- Admin API allows to manage trusted domain
