OpenFGA v1.17.0

This release focuses on hardening the internal caching engine for better security and performance while introducing more granular control over observability via industry-standard OpenTelemetry sampling strategies.

Hardened and Collision-Free Cache Key Generation — The new TLV binary encoding and per-process seeding protect OpenFGA against hash-flooding attacks while ensuring high-performance cache lookups are zero-collision. This increases the reliability of authorization decisions under high load or adversarial conditions.

Configurable OpenTelemetry Trace Sampling Strategies — Teams using distributed tracing can now better control telemetry costs and visibility by aligning OpenFGA sampling with their global OpenTelemetry strategies, including respecting sampling decisions made by upstream services.
