    Version 2.0.15

    Bug fixes

    • Fixes a issue where the Proxy could incorrectly detect a delta between cached Target Group/Flag configs and SaaS during a stream disconnect or on startup. This caused the Proxy to send unnecessary SSE event to SDKs, even when no changes occurred. (FFM-12608)

    Feature Flags by Harness

    Version 2.0.13

    SSE handling optimized for Proxy restarts/disconnections: patch events now only for changed resources, reducing updates, with automatic Redis migration on startup. Upgrading to 2.0.13 requires no action; downgrading to 2.0.12 requires a Redis DB index change.

    New features and enhancements

    • Optimized SSE event handling for Primary Proxy restarts or disconnections from Harness SaaS. The Proxy now sends patch events only for resources that changed while it was disconnected, instead of patching all flags. This reduces unnecessary updates and improves efficiency. The change is backward compatible and includes an automatic data structure migration in Redis on startup. (FFM-12528)

    Security and Maintenance

    • Updated Redis data model to support more efficient resource tracking during disconnections. While upgrading from Proxy version 2.0.12 or earlier to 2.0.13 requires no manual action, reverting back to 2.0.12 after an upgrade requires setting a different REDIS_DB index to avoid data incompatibility.

    Version 2.0.9

    New features and enhancements

    • Added support for rotating auth secrets without downtime or requiring SDK restarts.
    • Previously, updating the AUTH_SECRET invalidated existing SDK tokens. Now, you can assign a new AUTH_SECRET and move the old one to LEGACY_SECRETS. The Proxy will accept tokens signed with both. Once all SDKs are using tokens signed with the new secret, you can remove the legacy value.
