Release notes

Release Management

We’ve launched Release Management to help you standardize how you roll out new features. You can now define reusable release templates with milestones so you don’t have to manually configure the same rollout strategies across multiple flags. This reduces repetitive work, ensures consistent rollouts, and lowers release risk. Create new templates under Configure > Release templates.

Change request improvements

You now receive an email notification when you’re added as a reviewer to a change request. This helps you maintain momentum by speeding up the approval process.

Change requests also display a cleaner, formatted JSON diff that highlights only the changed values while still letting you expand for the full object. In the new View diff tab, you can review the changes in detail, and easily copy them without relying on tooltips.

In addition, to give you a clear timeline of progress, every state update to a change request now includes a timestamp.

Flag performance and lifecycle updates

We’ve added lifecycle metrics to the Analytics dashboard so you can see a snapshot of how many flags are currently in each major lifecycle stage: Develop, Production, and Cleanup. Each stage shows how many flags are new this week, how many have been there for more than a week, and the median time flags spend in that stage. You can also compare this to the historical median to spot outliers.

This gives you a clear picture of where flags may be stuck, helps you reduce technical debt, and connects engineering work to business outcomes.

To help reduce technical debt, Unleash now also suggests flags that are safe to archive. By analyzing usage, the platform highlights flags in the cleanup stage that haven’t been used for seven days so you can confidently archive them in bulk.

Project list improvements

The Project list view has been redesigned to make it easier to scan, even with a large number of projects. You can now switch between card and list views depending on which format you prefer, making navigation more flexible.

Unknown flag checker

Unleash now highlights any flags your SDKs try to evaluate that Unleash doesn’t recognize. You’ll see these in the Flags overview under Unknown flags, where you can review the full list to spot typos, fix misconfigurations, or remove stale references in your code. This helps keep your setup clean and in sync.

v7.1.0

Unleash 7.1

Feature flag lifecycle improvements

You can now mark any flag as Ready for cleanup, even if it never reached production. This helps you clean up flags at any stage in the lifecycle, for example, a kill switch you never enabled in production, and reduce technical debt.

We also renamed Health to Technical debt to align with common engineering terminology. In Project > Project status, you can see a technical debt rating for the project. In Analytics > Technical debt, you can explore the same data at the instance and project levels.

Renamed SDKs and token types

We’ve introduced a more consistent naming pattern for our SDKs and API tokens. Server-side SDKs are now backend SDKs, and client-side SDKs are frontend SDKs. Backend SDKs use backend tokens and frontend SDKs use frontend tokens.

You’ll find the new naming across our documentation and in the Admin UI, such as when creating API tokens or working with permissions. We also standardized SDK repository and registration names to follow the unleash-{language/framework}-sdk pattern. For example, unleash-client-python has been renamed to unleash-python-sdk. Note that SDK artifact names remain unchanged to avoid requiring changes to your codebase.

Grouped events in Event Log

Event Log now marks related events using a Group ID when a single action produces multiple changes. This makes the full sequence of changes easier to trace and audit.

For example, when a change request is approved and applied, all resulting events, such as strategy or flag config changes, appear under the same Group ID. Similarly, if enabling a flag in an environment automatically adds the default strategy, both events share the same Group ID to reflect that they came from the same action.

In addition, we’ve made the date filter optional and added filtering by ID on the Events API.

View connected frontend applications

To help debug frontend application connections, you can now view connected frontend applications inside Configure > Applications and in each project’s Applications tab. If an application uses both backend and frontend SDKs, both are shown on the application’s overview page.
