Pulse v6.4.3-rc.1 Release Notes

This preview makes large and mixed estates more dependable, with stronger resource identity, safer agent operations, faster recovery from slow starts, clearer workflows, and broader accessibility support.

What's improved

• Same-name systems stay separate - Stronger host, Docker, Kubernetes, and Proxmox identity checks reduce incorrect merges and keep alerts, metrics, actions, and removal tied to the right machine.
• Agent lifecycle operations are safer - Linux installs protect tokens under sudo, offline recovery verifies signed installers, shared credentials survive partial removal, and uninstall waits for confirmed server removal.
• Windows agent delivery is restored - Unified Agent downloads now resolve canonical signed .exe assets and signature sidecars, preventing asset lookup failures during installation and updates.
• Large Availability estates scan faster - Estates with 20 or more checks open in fleet view, while table and fleet choices remain stable across refreshes and shareable URLs.
• Slow starts are recoverable - Pulse shows connection status and a retry after delayed app startup, while large alert histories catch up incrementally in the background after server restarts.
• Alert workflows stay focused - Patrol opens findings for the affected resource, snooze blocks duplicate submissions, incident recovery is clearer, and delivery warnings link to detailed activity.
• Navigation is more accessible - Menus, dialogs, charts, toasts, filters, thresholds, and compact controls improve keyboard, screen-reader, focus, mobile, and reduced-motion support.
• Health APIs are consistent - Resource APIs provide canonical health verdicts and a bounded fleet summary, while missing or stale telemetry can no longer appear healthy.
• Disk I/O totals are more accurate - Partitions of NVMe, MMC, MD, persistent-memory, and ZFS volume devices no longer inflate whole-device traffic.
• Privileged actions fail more safely - Linux package and Proxmox operations run in bounded units, abandoned requests are cancelled, and uncertain outcomes are not reported as successful.
• Oversized responses are contained - Pulse applies response limits across agents, Proxmox, discovery, updates, remote configuration, AI providers, and other integrations to reduce memory pressure.

Before you upgrade

• This candidate carries every change from the v6.4.2 packet, which was tagged on 2026-08-31 but never published. If you run v6.4.1, read the v6.4.2 notes for the administrator-boundary changes as well.
• On an SSO-only deployment, map at least one trusted IdP group to the built-in admin role before upgrading so an intended administrator retains access.
• If the least-privilege agent monitors rootless Docker or Podman, ensure the collector account exposes exactly one local, collector-owned runtime socket. Ambiguous or invalid sockets may fall back to summary-only monitoring.
• Windows Unified Agent binaries are not Authenticode-signed while SignPath remains unavailable and may show an Unknown Publisher warning. Verify downloads with the published checksums and detached signatures.
• Pulse Mobile remains compatible. This candidate does not require a companion mobile release.
• The rollback target is stable v6.4.1. On systemd and Proxmox LXC installs, use sudo /bin/update --version v6.4.1 to return to the previous stable release.

Install

For systemd and Proxmox LXC installs, use Settings → System → Updates or:

sudo /bin/update --version v6.4.3-rc.1

For Docker:

docker pull rcourtman/pulse:6.4.3-rc.1

For Docker Compose, update the image to rcourtman/pulse:6.4.3-rc.1 and recreate the container.

Pulse Pro and Relay customers should continue using the private download page and private runtime image for paid features.

Roll back

The rollback target is v6.4.1:

sudo /bin/update --version v6.4.1

For Docker Compose, set the Pulse image to the rollback target and recreate the container.
