• Add automatic intercepting of print calls and append them to response.output. This makes more libraries work out of the box, as printing would previously cause an error due to communication over stdin/stdout.
    • Note that using stdin/stdout directly will still cause an error, but that is less common.


  • Add better handling for the case where stdin gives an error instead of an EOF.


  • Export AsyncMessageGrouper and SyncMessageGrouper as part of the testing library. These can assist when writing e2e tests and communicating with a worker process.


  • Initial version.
