October 2026 Cloud Release Notes

October 5, 2026 - Minor Release

Custom Slack alarm messages

The alarm-channel editor now supports custom Slack messages built from Section, Context, and Message blocks. Section blocks lay out selected fields in two columns with editable labels. Context blocks show supporting fields as compact metadata. Message blocks let you write free-form text and optionally insert alert values. Choose and arrange the blocks and fields to fit your alert; the examples in the Slack channel documentation are not required defaults.
