The new version brings the following:

  • adds gzip encoding to HTTP requests
  • adds keep-alive HTTP headers
  • adds -noKeepAlive option to turn off keep-alive header
  • adds GODEBUG=asyncpreemptoff=1 option on Linux to prevent race condition on AFS
  • change details DBS query on file dataset=... DAS query when user does not provide -json flag and when no DAS filters are used. This will significantly reduce DBS output for large datasets
  • adds dnsCache option to avoid extensive DNS queries of cmsweb.
  • adds binary build on macOS using Apple Silicon chip
