OpenFGA v1.13.0 ships AuthZen v1.0 support, separates Check v1/v2 caches, and hardens the resolver pipeline against panics.

• enhancementEvaluate AuthZen v1.0 for cross-system authorization interop

  AuthZen v1.0 is the emerging standard for authorization API interoperability across CNCF and broader ecosystem tools. If you're integrating OpenFGA with other policy engines or building a multi-system authz layer, test the new AuthZen endpoint now. Early adoption means your integration patterns align with where the ecosystem is heading rather than needing a retrofit later.

• breakingSeparate Check v1/v2 caches may change cache hit behavior — review your cache sizing

  Previously, Check v1 and v2 shared a single cache, which could lead to cross-contamination but also inadvertent cache hits. Now they're isolated. If you're running both API versions concurrently, your effective cache hit rate may drop and memory usage could shift. Revisit your cache capacity configuration after upgrading and monitor cache hit ratios in your observability stack.

• securityUpgrade to stop resolver panics from taking down the server

  Unhandled panics in the pipeline base resolver previously had the potential to crash the OpenFGA process entirely. The fix converts these to returned errors, keeping the server running. If you've seen unexpected OpenFGA restarts under complex authorization graph evaluations, this is likely why. Upgrade promptly — this is a reliability fix with meaningful availability implications.
