## About the changes
When deleting a user we set the email to null and deleted_at to the
current date, there's no case where email is set and deleted_at is also
set.
We found some situations where this happens, specifically when SAML and
SCIM are used in conjunction
## About the changes
Having SCIM enabled with SAML and auto-create can generate issues with
each protocol stepping into the other protocol's toes.
This PR adds protection to avoid updating SCIM-managed users with SAML
data (cause SCIM will override this data later).
It also adds a new method in the store to check if we have cases where
deleted_at is set but the email is not cleared, and there's no delete
event in the audit log (we've found one case, and we believe it might be
related to interoperability issues between SAML and SCIM)
This PR cleans up the addConfiguration flag. These changes were
automatically generated by AI and should be reviewed carefully.
Fixes#10627
## 🧹 AI Flag Cleanup Summary
This change removes the `addConfiguration` feature flag. The feature was
discarded, so this cleanup reverts the UI to its state before the
`addConfiguration` flag was introduced. The primary change is in the
strategy
menu, where the single "Add configuration" button is removed and the
original
"Use template," "Add strategy," and "More" buttons are restored.
### 🚮 Removed
- **Flag Definitions**
- `addConfiguration` flag from `experimental.ts` on the backend.
- `addConfiguration` flag from `uiConfig.ts` on the frontend.
- `addConfiguration: true` from the `server-dev.ts` config.
- **UI Components & Logic**
- The conditional rendering in `FeatureStrategyMenu.tsx` that showed an
"Add
configuration" button.
- The `useUiFlag('addConfiguration')` hook call and its import from
`FeatureStrategyMenu.tsx`.
### 🛠 Kept
- **UI Components & Logic**
- The original set of buttons in `FeatureStrategyMenu.tsx`: "Use
template",
"Add strategy", and a "More strategies" icon button. This was the code
path for
when the flag was disabled.
### 📝 Why
The `addConfiguration` feature flag was marked as completed with the
outcome
"discarded". This cleanup removes the flag and all related code,
preserving only
the intended code path, which is the UI behavior from before the flag
was
introduced.

automatically generated by AI and should be reviewed carefully.
Fixes#10595
## 🧹 AI Flag Cleanup Summary
This change removes the `reportUnknownFlags` feature flag and makes its
functionality a permanent part of the application. The "Unknown flags"
feature
is now always enabled.
### 🚮 Removed
- **Flag Definitions**
- Removed `reportUnknownFlags` from `IFlagKey` and `UiFlags` types.
- Removed `reportUnknownFlags` from the experimental flags configuration
in `src/lib/types/experimental.ts`.
- Removed the flag from development and test configurations
(`src/server-dev.ts`, `unknown-flags.e2e.test.ts`).
- **Conditional Logic**
- Removed conditional checks for `reportUnknownFlags` in backend
services
(`UnknownFlagsService`, `ClientMetricsServiceV2`) and API controllers
(`UnknownFlagsController`).
- Removed `useUiFlag('reportUnknownFlags')` and related conditional
rendering from frontend components (`UnknownFlagsTable`,
`FeatureToggleListTable`). The UI elements are now always visible.
- Modified the `useUnknownFlags` hook to always fetch data.
### 🛠 Kept
- **Core Functionality**
- The feature to report and display unknown flags is now always active.
- The "Unknown flags" link is now permanently visible on the feature
flags
overview page.
- Backend logic for processing and storing unknown flags is now always
executed.
### 📝 Why
The `reportUnknownFlags` feature flag was marked as completed with the
feature
being kept. This cleanup removes the flag and its associated conditional
logic,
simplifying the code and making the unknown flags reporting a permanent
feature.

This PR cleans up the etagByEnv flag. These changes were automatically
generated by AI and should be reviewed carefully.
Fixes#10556
## 🧹 AI Flag Cleanup Summary
This change removes the `etagByEnv` feature flag and makes its
functionality
permanent. This modifies the ETag generation for client API requests to
be
environment-specific, improving caching efficiency. The cleanup involved
removing the flag definition, updating the controller logic to
permanently use
the environment-specific ETag calculation, and refactoring the
corresponding E2E
tests to only cover the enabled behavior.
### 🚮 Removed
- **Flag Definition**
- The `etagByEnv` flag from `IFlagKey` in
`src/lib/types/experimental.ts`.
- **Conditional Logic**
- The check for the `etagByEnv` flag in `calculateMeta` method in
`src/lib/features/client-feature-toggles/client-feature-toggle.controller.ts`.
- **Tests**
- Test cases in `src/test/e2e/api/client/feature.optimal304.e2e.test.ts`
that
covered the disabled state of the `etagByEnv` flag.
### 🛠 Kept
- **Environment-Specific ETags**
- The behavior of generating environment-specific ETags is now the
default and
only behavior.
- **Tests**
- E2E tests verifying the functionality of environment-specific ETags
have
been retained and simplified.
### 📝 Why
The `etagByEnv` feature has been successfully rolled out and validated.
By
removing the feature flag and associated conditional logic, we simplify
the
codebase, reduce complexity, and make it easier to maintain. This change
makes
the improved ETag generation strategy a permanent part of the system.

was used
to enable additional logging for debugging ETag generation for the
client
features endpoint.
### 🚮 Removed
- **Flag Definition**
- The `debugEtag` flag from the `IFlagKey` type in
`src/lib/types/experimental.ts`.
- **Conditional Logging**
- Removed logging statements guarded by the `debugEtag` flag in
`client-feature-toggle.controller.ts` and
`configuration-revision-service.ts`.
### 🛠 Kept
- **Default Behavior**
- The existing code paths for when the flag was disabled, which is now
the
only behavior.
### 📝 Why
The `debugEtag` flag was marked as completed with the outcome
"discarded". The
debugging functionality it provided is no longer needed. This change
removes the
dead code associated with the flag, simplifying the codebase.

## About the changes
In the previous fix: https://github.com/Unleash/unleash/pull/10543, we
made sure client token types were displayed in the UI. Here, we're also
making sure that the Backend token types are displayed as well.
1. A test validates that if a backend token exists in the db it will be
returned in the API response.
2. The UI has been adapted to also consider backend token types
Internally token types are still identified as CLIENT, therefore when we
filter the ones we're allowed to see, we should still consider them as
CLIENT tokens not BACKEND tokens. This is internal until we can fully
remove CLIENT with the next major.

## About the changes
This ignores Change Request event types when calculating the etag
because Change Request events don't change data.
They were being included when the change request event contained a
featureName. After this change, those should be excluded.
We will start separating traffic, when it comes from different origins.
Also will add it as primary key so merging will work correctly.
There is a problem with using normal down migration, is that if we split
data by origin, when down migrating and removing column, and re adding
the old migration, we will have conflicts and it will fail.
This means before we down migrate, we need to aggregate/sum the data and
only then we can reapply old schema.
## About the changes
This sets the minimum version for the new SDK names to the current
latest version. The versions with the new SDK name will be newer, but
this will set the baseline for the future.
https://linear.app/unleash/issue/2-3738/clear-unknown-flags-every-24h-instead-of-every-7d
Clears unknown flags every 24h instead of every 7d.
This ensures the list stays more relevant by removing stale entries
sooner, allowing users to focus on actively reported unknown flags.
Also includes small improvements, including a new paragraph on the
unknown flags page that better explains the concept of unknown flag
reports.
## About the changes
Previous PR: https://github.com/Unleash/unleash/pull/10439 introduced a
bug not allowing to update the strategy name
This PR modifies a test to also validate the change of strategy and
fixes the problem
## About the changes
When stickiness was set to empty or undefined while updating a strategy
via API the stickiness would be lost.
This adds a validation step after creating a strategy, that updating
with the same data used to create the strategy yields the same result.
The main change was lifting the default logic from the store layer to
the service layer and adapting tests accordingly

## About the changes
Rebrand SDK tokens and SDK types to make it easier to onboard and use:
**Backend SDK Token**: Intended for server-side SDKs. It can be used to
access:
- The Client Features API (/api/client/features) for fetching all flag
configurations for local evaluation.
- The Frontend API (/api/frontend) for remote evaluation.
**Frontend SDK Token**: Intended for client-side/frontend SDKs. It is
restricted and can only be used to access:
- The Frontend API (/api/frontend) for remote evaluation.
---------
Co-authored-by: Nuno Góis <github@nunogois.com>
When querying invalid tokens we might catch them for a while to reduce
database load. Being able to identify the token can help understanding
what's going on or the client using that token
Log looks like:
```
[INFO] /services/api-token-service.ts - Token default:development.3ef3... rate limited until: Tue Jul 29 2025 09:53:47 GMT+0000 (Coordinated Universal Time)
```
When deleting stale sessions, we sort them by createdAt. If both
sessions are created with the same createdAt, there's a chance we get a
different sort order and we end up with the wrong order:
https://github.com/Unleash/unleash/actions/runs/16438565746/job/46453700977
I think adding 10ms between inserts should be enough (1ms should do,
but this gives me more confidence and doesn't hurt that much)

https://linear.app/unleash/issue/2-3696/report-unknown-flags-when-sent-to-the-bulk-metrics-endpoint
Unifies metrics sifting logic across both metrics endpoints:
- `/metrics`
- `/metrics/bulk`
This PR improves consistency between the `/metrics` and `/metrics/bulk`
endpoints by introducing a shared `siftMetrics` method, now used within
`registerBulkMetrics`. Both endpoints already call this method at the
end of their respective logic flows, ensuring that metrics are sifted in
the same way regardless of the path taken.
While the primary goal was to enable reporting of unknown flags via the
`/metrics/bulk` endpoint, this change also improves bulk processing by
consistently dropping invalid or unknown flags before insertion, just
like in the regular `/metrics` endpoint.
Fixes a bug in the instance store where insert and bulkUpsert would
overwrite existing properties if there was a row there already. Now
it'll ignore any properties that are undefined.
The implementation is lifted directly from
`src/lib/db/client-applications-store.ts` (line 107 atm).
Additionally, I've renamed the `insert` method to `upsert` to make it
clearer what it does (and because we already have `bulkUpsert`). The
method seems to only be used in tests, anyway. I do not anticipate any
changes to be required in enterprise (I've checked).
## Discussion points:
This implementation uses `delete` to remove properties from the object.
Why didn't I do it some other way? Two main reasons:
1. We've had this implementation for 4 years in the client applications
store. If there were serious issues with it, we'd probably know by know.
(Probably.)
2. The only way I can think of without deleting, would be to use
`Object.fromEntries` and `Object.toEntries` and either map or reduce.
That'll double the amount of property iterations we'll need to do.
So naively, this strikes me as being more efficient. If you know better
solutions, I will of course be happy to take them. If not, I'd like to
leave this as is and then change it if we see that it's causing issues.
Fixes a bug where `registerInstance` and
`register{Frontend|Backend}Client` would overwrite each other's data in
the instance service, leading to the bulk update being made with partial
data, often missing SDK version. There's a different issue in the actual
store that causes sdk version and type to be overwritten when it's
updated (because we don't use `setLastSeen` anymore), but I'll handle
that in a different PR.
This PR adds tests for the changes I've made. Additionally, I've made
these semi-related bonus changes:
- In registerInstance, don't expect a partial `IClientApp`. We used to
validate that it was actual a metrics object instead. Instead, update
the signature to expect the actual properties we need from the cilent
metrics schema and set a default for instanceId the way Joi did.
- In `metrics.ts`, use the `ClientMetricsSchema` type in the function
signature, so that the request body is correctly typed in the function
(instead of being `any`).
- Delete two unused properties from the`createApplicationSchema`. They
would get ignored and were never used as far as I can tell. (`appName`
is taken from the URL, and applications don't store `sdkVersion`
information).
- Add `sdkVersion` to `IClientApp` because it's used in instance
service.
I've been very confused about all the weird type shenanigans we do in
the instance service (expecting `IClientApp`, then validating with a
different Joi schema etc). I think this makes it a little bit better and
updates the bits I'm touching, but I'm happy to take input if you
disagree.
This type wasn't available in enterprise, so I'm adding it to serer-impl
to make it available.
I was a little unsure whether this would be an implementation detail
that we shouldn't expose in server-impl, but comparing it with the other
things we export (`applyGenericQueryParams`, `flattenPayload`,
`basePaginationParameters`), that seems to be fine. I'm guessing this
isn't the main public export? Or it is, and we just don't care 🤷
