Added

• Timestamp Bloblang methods are now able to emit and process time.Time values.
• New ts_tz method for switching the timezone of timestamp values.

• Go API: Added component bundle ./public/components/aws for all AWS components, including a RunLambda function.
• New cached processor.
• Go API: New APIs for registering both metrics exporters and open telemetry tracer plugins.
• Go API: The stream builder API now supports configuring a tracer, and tracer configuration is now isolated to the stream being executed.
• Go API: Plugin components can now access input and output resources.
• The redis_streams output field stream field now supports interpolation functions.
• The kafka_franz input and outputs now support AWS_MSK_IAM as a SASL mechanism.

• Go API: Fixed an issue where running the CLI API without importing a component package would result in template init crashing.
• The http processor and http_client input and output no longer have default headers as part of their configuration. A Content-Type header will be added to requests with a default value of application/octet-stream when a message body is being sent and the configuration has not added one explicitly.
• Logging in logfmt mode with add_timestamp enabled now works.

• Ability to write logs to a file (with optional rotation) instead of stdout.

Fixed

• 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.

For installation instructions check out the getting started guide.

Added

• The nats_jetstream input now adds headers to messages as metadata.

• Bloblang comparisons between numerical values (including match expression patterns) no longer require coercion into explicit types.
• Reintroduced basic metrics from the twitter and discord template based inputs.
• Prevented a metrics label mismatch when running in streams mode with resources and prometheus metrics.

Added

• New sql_raw processor and output.

Fixed

• Corrected a case where nested parallel processors that result in emptied batches (all messages filtered) would propagate an unack rather than an acknowledgement.

Changed

• The sql processor and output are no longer marked as deprecated and will therefore not be removed in V4. This change was made in order to provide more time to migrate to the new sql_raw processor and output.
