Motivation and Context
The Rust feature flags definitions fleet now serves 100% of
/api/feature_flag/local_evaluationtraffic in all environments. This switches the SDK's default polling URL from the legacy Django path to the Rust endpoint's native path (/flags/definitions).The old
/api/feature_flag/local_evaluationpath remains registered as a route alias on the Rust service, so older SDK versions continue to work.How did you test it?
/flags/definitionsendpoint has been serving production traffic since 2026-04-09
