v8.0.0

Breaking changes (types)

• The SignalNumber and Signal['number'] types in TypeScript are now stricter. They only allow valid signal numbers like 1 or 9. They do not allow invalid signal numbers like -1, 1.5 or 999. Please note that 0 is not considered a valid signal number, although it can be passed to process.kill().

Types

• The signalsByName[signalName] and signalsByNumber[signalNumber] types in TypeScript are now Signal instead of Signal | undefined. This means you can now do signalsByName[signalName].description instead of signalsByName[signalName]!.description.
