# Pulse v4.26.1

## What's Changed
### New
- Standalone host agents now ship with guided Linux, macOS, and Windows installers that stream registration status back to Pulse, generate scoped commands from **Settings → Agents**, and feed host metrics into alerts alongside Proxmox and Docker.
- Alert thresholds gained host-level overrides, connectivity toggles, and snapshot size guardrails so you can tune offline behaviour per host while keeping a global policy for other resources.
- API tokens now support fine-grained scopes with a redesigned manager that previews command templates, highlights unused credentials, and makes revocation a single click.
- Proxmox replication jobs surface in a dedicated **Settings → Hosts → Replication** view with API plumbing to track task health and bubble failures into the monitoring pipeline.
- Docker Swarm environments now receive service/task-aware reporting with configurable scope, plus a Docker settings view that highlights manager/worker roles, stack health, rollout status, and service alert thresholds.

### Improvements
- Dashboard loads and drawer links respond faster thanks to cached guest metadata, reduced polling allocations, and inline URL editing that no longer flashes on WebSocket updates.
- Settings navigation is reorganized with dedicated Docker and Hosts sections, richer filters, and platform icons that make agent onboarding and discovery workflows clearer.
- LXC guests now report dynamic interface IPs, configuration metadata, and queue metrics so alerting, discovery, and drawers stay accurate even during rapid container churn.
- Notifications consolidate into a consistent toast system, with clearer feedback during agent setup, token generation, and background job state changes.

### Bug Fixes
- Enforced explicit node naming and respected custom Proxmox ports so cluster discovery, overrides, and disk monitoring defaults remain intact after edits.
- Hardened setup-token flows and checksum handling in the installers to prevent stale credentials and guarantee the correct binaries are fetched.
- Treated 501 responses from the Proxmox API as non-fatal during failover, restored FreeBSD disk counter parsing, and stopped guest link icons from re-triggering animations on updates.
- Preserved inline editor state across WebSocket refreshes and ensured Docker host identifiers stay collision-safe in mixed environments.
