Improvements & Fixes

  • Node.js: Inherits core layer-sampling fix and evaluator performance improvements.
  • Java: Inherits core layer-sampling fix and evaluator performance improvements.
  • Python:
    • Fix numeric coercion for large integer user.custom values that previously broke evaluation.
    • Faster typed DynamicConfig/Experiment accessors (get_string, get_integer, get_float, get_bool, get_array, get_object) — up to ~37% faster per call.
    • Inlined the error-boundary wrapper to remove per-call overhead — ~8–17% faster gate/config/experiment/layer evaluation.
  • Rust:
    • Layers now pull the sampling rate from the experiment's rule in the config-delegate case.
    • Removed hash-input allocations in the evaluator hot path (~5–9% faster checks).
    • Skip SDK event-listener lookups when no listeners are subscribed.
  • .NET: Inherits core layer-sampling fix and evaluator performance improvements.
  • Elixir: Preserve user.custom integers above i64::MAX (fall back to f64) instead of raising in the NIF.
