v0.3.4

• Changed. Accepts rasuvaeff/understudy ^0.11 alongside ^0.9 || ^0.10: the engine's 0.11.0 adds a refusal where there was a fatal, a nested-call check and a returns() type check, none of which this package reads; the bridge is widened, not moved. The returns() check found one in this package's own Fiber fixture — returns(true) on a : void gate — which is now the plain expect() it meant.
