# 0.7.1 Added `Exception` for `UsageError`. # 0.7 Simplified the implementation a lot by removing the notion of timeout. Breaking: - Removed the `Settings` type - Changed the signature of `acquire` # 0.6 Moved away from "resource-pool" and fixed the handling of lost connections. Breaking: - Changed the suffix of `UsageError` constructors from `Error` to `UsageError` - Added `PoolIsReleasedUsageError`
