Changelog

5 bug fixes

  • Vector’s VRL REPL no longer loses variable assignments when the expression errors.
  • Vector’s docker images no longer need a volume mounted at /var/lib/docker to run correctly with the default data_dir configuration.
  • AWS components now allow configuration of the load timeout for credentials (load_timeout_secs). In 0.21.0, the default load timeout was inadvertently changed to the new default timeout of the new Rust AWS SDK which dropped it from 30 seconds to 5 seconds. This new configuration option allows configuring it a higher value when necessary.
  • vector generate now works correctly again when datadog_agent is used as a source rather than logging an error.
  • AWS components now check for a region at Vector start-up time so that they return an error rather than starting but failing to make requests later due to the lack of region configuration.
