Release notes

If you self-host Unleash, review the v7 to v8 migration guide before you upgrade. No API endpoints were removed, but several deprecated schema properties have been.

Unleash MCP server is now generally available

The Unleash MCP server is now generally available. It gives your AI coding assistants a structured contract for managing feature flags safely, guiding them through evaluating risk, creating flags, wrapping code, and cleaning up after a rollout. It works with tools like Claude Code, Cursor, GitHub Copilot, Kiro, and OpenCode.

Project-level context fields

Context fields can now be defined at a per-project level. To create one, open a project and go to Settings > Context fields. Once you define project-level context fields, they are available in strategy configuration and the playground for users with access to that project, but are not included in the global context fields overview.

User groups with root roles can now be assigned to projects

Previously, groups with a root role could not be added to projects in the Admin UI. This restriction has been removed. You can now add any group to a project regardless of whether it has a root role. This is especially useful for teams that sync groups from SSO providers, as it removes the need to maintain separate groups for root-level and project-level access.

Enterprise Edge observability

We extended the observability dashboard for Unleash Enterprise Edge. The dashboard provides visibility into the health and performance of your hosted or self-hosted Enterprise Edge nodes directly within the Unleash Admin UI.

Key metrics include:

Improved experience for adding strategies to flags

We redesigned how you add activation strategies to flags. The new flow makes it easier to access standard strategies and reusable release templates. When you configure a flag in an environment, click Add strategy and choose one of the following options:

• The project’s default strategy
• A standard strategy, such as gradual rollout or on/off
• An advanced strategy, such as IP or host targeting
• A release template
• A custom activation strategy defined in your instance

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.

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.

Flag cleanup reminders and automation

To help you stay on top of technical debt, we’ve introduced automated reminders for flag cleanup.

When a feature flag reaches its intended cleanup date and we no longer detect metrics, we’ll remind you to change its lifecycle status to Cleanup. This highlights the flag in the UI, making it clear which flags are ready to be removed.

Improved user roles and permissions overview

We’ve added a new Access overview page for each user, making it easier for administrators to see exactly what a user can do in Unleash and which roles grant those permissions. You can explore permissions at the root level or for specific environments and projects. To view a user’s permissions, go to Admin settings > Users. Select a user and click Access overview.

Observability metrics for Edge

We’ve introduced a new dashboard that provides detailed observability metrics for Unleash Edge, helping teams efficiently manage all their connected Edge instances. The dashboard offers a high-level view of all Edge instances, with deeper insights into instance ID, region, CPU and memory usage, and upstream/downstream latency. This data helps you ensure that all instances are operational and quickly identify potential issues. You can access these metrics in Network > Connected Edges for Edge instances on version 19.7.0 or later.

Renamed feature flag lifecycle stages

We’ve updated the names of the feature flag lifecycle stages to better mirror a typical software development process and help you improve your release efficiency and workflows.

The changes include updates to the names, icons, and colors for the different stages.

Simplified projects

We’ve simplified the experience of managing your projects in Unleash. On the project overview page, you can now use filters to access archived or stale flags.

Additional enhancements, such as tooltips and accessibility improvements, provide a more consistent and focused experience.
