1.53.0 (2026-05-15)

🎉 GO Feature Flag v1.53.0

This is an important release for GO Feature Flag, it brings a lot of improvement to the performance of GOFF, 1st we've improved the caching of your rules in order to be faster to evaluate your targeting rules, and if you are using the exporters, we have rework the locking mechanism to speedup your evaluations.

But this is not it, we've adding some new features too.

🚀 New Features

If you are using the OpenFeature cli, you can now use the new manifest endpoint defined to work with the cli.
You can now pull your configuration using the cli directly by doing

openfeature pull --provider-url http://localhost:1031

it will download directly the manifest from the relay-proxy.

Real-time flag change streaming (SSE)

The relay proxy now supports Server-Sent Events (SSE) for flag change notifications, powered by r3labs/sse. Clients can subscribe to flag change events in real time without polling, which is a foundational building block for responsive feature flag SDKs.

This SSE will also allow GOFF to work with the latest spec changes from the OFREP protocol.

⚡ Performance (modules/core v0.7.1)

Targeting rule evaluation caching
Parsed nikunjy targeting query evaluators are now cached at the rule level. Previously, each evaluation would re-parse the targeting expression from scratch. This significantly reduces CPU overhead in high-throughput scenarios where the same rules are evaluated repeatedly across many requests.

Other changes

As usual we are also increasing security in the repo, doing dependency updates, and ensuring that we deliver the best quality as usual.

• relayproxy: add GET /openfeature/v0/manifest endpoint (#5210) (95c8e76)
• relayproxy: SSE flag change streaming with r3labs/sse (#5216) (49f03ca)
