5.4.2

Fixed

• Avoid crash when TimeInterval configuration options are set to sufficiently large values. This was caused when converting these values to an Int value of milliseconds. (Thanks, @delannoyk!)
• Update Package.swift to use SwiftPM tools version 5.2. This prevents test dependencies from being included transitively. (Thanks, @escakot!)
• Update Quick test dependency to 3.1.2 to avoid build warnings and adopt security fixes. (#243)
• Use AnyObject over class in protocol inheritance to avoid compiler warnings. (#247)
• Improve CI to test against multiple supported Xcode and Swift language versions.
• Restored test suite compatibility with Xcode 11.4 and Swift 5.2.
