Dec 1, 2024

December 2024 — Canonical Solutions Engineering Automation (canonical/solutions-engineering-automation): Focused on stabilizing cross-project configurations and eliminating a source of template conflicts. Implemented a configuration compatibility fix by temporarily disabling the check.yaml configuration across charm-prometheus-juju-exporter, prometheus-juju-exporter, and hardware-observer-operator, to avoid conflicts with a different template. The change was implemented by commenting out the relevant Terraform variable sections and tracked in the commit 94fa4266946be99d21b0617ad950abdbf744bb4c (related to issue #134).
