2.5.1

What's Changed

Packaging

• Debian 13 (trixie) and Ubuntu 26.04 LTS (resolute) are now built and published to the packages.redis.io APT repository, fixing installation on those releases (#511).
• Fixed Ubuntu armhf/arm64 package builds. The Ubuntu arm ports mirror (ports.ubuntu.com) is unreachable from the CI runners; every Ubuntu arm64/armhf .deb had been failing to build. debian/setup_sbuild.sh now uses a reachable mirror (with the correct /ubuntu-ports path), so arm packages publish again across all Ubuntu codenames.

Observability

• Added a Grafana dashboard for the Prometheus /metrics exporter (grafana/dashboards/prom-memtier.json), with import instructions in the real-time metrics docs (#510).

Docs

• README now lists the supported APT platforms: Debian 11/12/13 and Ubuntu 20.04/22.04/24.04/26.04.
