Pulse v6.4.0-rc.5 Release Notes

v6.4.0-rc.5 is a release candidate for the next v6 minor release. It makes API-token removal durable, exposes notification decisions more clearly, and moves alert lifecycle handling onto a deterministic transition core.

What's improved

• Clearer notification evidence — Active alerts show delivery status, and the delivery activity view includes held notifications and their suppression reasons.
• More reliable alert lifecycles — Metric, availability, health, posture, backup, snapshot, storage, and update alerts now share a deterministic transition core with pinned confirmation, recovery, acknowledgement, and re-fire behavior.
• Safer agent setup — Agent install commands reveal their newly generated token separately, making it easier to copy the credential without mixing it with the shell command.
• Better filesystem feedback — Filesystem history drawers again show loading progress while a longer range is fetched.

Fixes

• API-token deletion now persists the reduced inventory atomically and restores the complete prior live inventory if saving fails, instead of reporting success with inconsistent credentials (#1783).
• Alert delivery diagnosis now distinguishes pending, sent, failed, and suppressed outcomes without requiring operators to infer delivery from an active alert alone.
• Confirmation-based alerts retain the first matched observation as their occurrence start, and new confirmation runs no longer inherit stale timestamps.
• Canonically keyed metric alerts resolve through the same identity used to create them instead of remaining stale after recovery.
• Stateful alert manual clears preserve acknowledgement and recent-resolution behavior so a quick refire does not duplicate history.
• Guest and host memory percentages use the same cache-aware basis in operator-facing explanations.

Before you upgrade

• This is a release candidate. Stable installations remain on v6.3.2 unless an operator explicitly selects this version.
• Existing configurations remain valid and no manual data migration is required.
• Pulse Mobile does not consume the changed alert transition internals or browser delivery evidence. Existing mobile, Relay, onboarding, pairing, push, and mobile-facing API contracts are unchanged, so no companion update is required.
• Windows Unified Agent binaries are checksum- and detached-signature-verified but are not Authenticode-signed, so Windows may show an Unknown Publisher warning.

Known issues

• Windows Authenticode signing remains unavailable for this candidate; use the published checksum and detached signature when verifying Windows agent downloads.

Install

docker pull rcourtman/pulse:6.4.0-rc.5

For Docker Compose, update the image to rcourtman/pulse:6.4.0-rc.5 and recreate the container.

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