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 v6.6.0
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.
Data usage date range selector
The Data Usage dashboard now provides an aggregated view of your requests to Unleash over the last 3, 6, or 12 months—making it simple to track and assess your data usage over time. You can also compare your usage in previous months with the current month. Access the dashboard in Network > Data Usage.
Event Timeline now lives in Dashboard
We have moved Event Timeline to the top of Dashboard for a more seamless experience and easier access.
