This page provides a high-level summary of releases starting from 2025. It details new functionality, UI changes, deprecations, and important announcements across Unleash and its components.
How to use the tags
Each release note is tagged with the part of the product it applies to. Use the tags to filter for the areas you’re interested in.
- Unleash: The core platform, including the Unleash server, the Admin UI, and overarching product decisions and announcements. See the architecture overview.
- Enterprise Edge: Releases for Unleash Enterprise Edge, a lightweight caching layer that improves the scalability, performance, and resilience of your feature flag infrastructure.
- MCP server: Releases for the Unleash MCP server, which lets AI coding assistants manage feature flags.
- SDKs: Changes that affect the Unleash SDKs, such as naming changes or new capabilities that span multiple SDKs.
A single release note can carry more than one tag when a release touches several areas.
Versioning
Unleash follows semantic versioning, with major versions (for example, v7.0.0) including significant new features and might include breaking changes, and minor versions (for example, v7.4.0) adding new functionality while maintaining backward compatibility.
For a comprehensive list of all Unleash releases, including patch versions and history prior to 2025, visit the Unleash Releases page on GitHub.
The Unleash MCP server, Unleash Enterprise Edge, and each SDK are versioned independently and publish their own changelog in their respective GitHub repositories.
Unleash v6.5.0
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.
Updated license policy for self-hosted Enterprise
Since Unleash v6.0, we’ve had soft limits in place warning self-hosted Enterprise instances operating without a valid license or exceeding their seat count. With Unleash v6.7, we have introduced the following restrictions:
Mandatory license for enterprise self-hosted plan
If you don’t have a valid license, your Unleash instance enters read-only mode, and the only available action is to install a valid license.
License expiration
When your license expires, your Unleash instance enters read-only mode. The only available action is to install a new, valid license. Connected applications continue to operate and receive current feature flags, but users cannot make any changes to Unleash.
Seat count
If you reach the maximum number of seats in your license, you cannot add new users until you remove existing users to stay within your limit. The Unleash Admin UI displays warning banners for customers approaching or exceeding the terms of their license.
