• POSSIBLY BREAKING: Updated swift-tools version to 5.3, and added a fallback version of Package.swift for 5.2. (#1584)
• BREAKING, technically: Switched cachePolicy to a var on HTTPRequest. This makes it possible for retries to use a different cache policy, such as when an error has occurred at the network level and you want to fall back to showing what's in the cache without retrying the network call. (#1569)
• Added validation in Swift Codegen wrapper that a URL passed in for singleFile code generation is a .swift file and a URL passed in for multipleFiles code generation is a folder. (#1580)
