benthosdev/benthos v4.2.0 on GitHub

For installation instructions check out the getting started guide.

Field credentials.from_ec2_role added to all AWS based components.
The mongodb input now supports aggregation filters by setting the new operation field.
New gcp_cloudtrace tracer.
New slug bloblang string method.
The elasticsearch output now supports the create action.
Field tls.root_cas_file added to the pulsar input and output.
The fallback output now adds a metadata field fallback_error to messages when shifted.
New bloblang methods ts_round, ts_parse, ts_format, ts_strptime, ts_strftime, ts_unix and ts_unix_nano. Most are aliases of (now deprecated) time methods with timestamp_ prefixes.
Ability to write logs to a file (with optional rotation) instead of stdout.

The default docker image no longer throws configuration errors when running streams mode without an explicit general config.
The field metrics.mapping now allows environment functions such as hostname and env.
Fixed a lock-up in the amqp_0_9 output caused when messages sent with the immediate or mandatory flags were rejected.
Fixed a race condition upon creating dynamic streams that self-terminate, this was causing panics in cases where the stream finishes immediately.
