Setting the revision to "HEAD", "FETCH_HEAD", "ORIG_HEAD", "MERGE_HEAD" or "CHERRY_PICK_HEAD" is no longer allowed.
v1.4
Breaking change: Some debug metrics for otelcol components have changed
For example, otelcol.exporter.otlp’s exporter_sent_spans_ratio_total metric is now otelcol_exporter_sent_spans_total.
You may need to change your dashboard and alert settings to reference the new metrics.
Refer to each component’s documentation page for more information.
Breaking change: The convert_sum_to_gauge and convert_gauge_to_sum functions in otelcol.processor.transform change context
The convert_sum_to_gauge and convert_gauge_to_sum functions must now be used in the metric context rather than in the datapoint context.
This is due to a change upstream.
Breaking change: Renamed metrics in beyla.ebpf
process.cpu.state is renamed to cpu.mode and beyla_build_info is renamed to beyla_internal_build_info.
v1.3
Breaking change: remotecfg block updated argument name from metadata to attributes

This feature is in Public preview and is not covered by Grafana Alloy backward compatibility guarantees.
The remotecfg block has an updated argument name from metadata to attributes.
v1.2
Breaking change: remotecfg block updated for Agent rename
Note
This feature is in Public preview and is not covered by Grafana Alloy backward compatibility guarantees.
The remotecfg block has been updated to use alloy-remote-config
over agent-remote-config. This change
aligns remotecfg API terminology with Alloy and includes updated endpoints.
