Use Info.BandwidthBytes converted to MB/s with float division so
bandwidth alert checks are based on current data without integer
truncation near thresholds.
* feat: add outbound heartbeat monitoring to external endpoints
Allow Beszel hub to periodically ping an external monitoring service
(e.g. BetterStack, Uptime Kuma, Healthchecks.io) with system status
summaries, enabling monitoring without exposing Beszel to the internet.
Configuration via environment variables:
- BESZEL_HUB_HEARTBEAT_URL: endpoint to ping (required to enable)
- BESZEL_HUB_HEARTBEAT_INTERVAL: seconds between pings (default: 60)
- BESZEL_HUB_HEARTBEAT_METHOD: HTTP method - POST/GET/HEAD (default: POST)
* SMART: add eMMC health via sysfs
Read eMMC wear/EOL indicators from /sys/class/block/mmcblk*/device and expose in SMART device list. Includes mocked sysfs tests and UI tweaks for unknown temps.
* small optimizations for emmc scan and parsing
* smart: keep smartctl optional only for Linux hosts with eMMC
* update smart alerts to handle warning state
* refactor: rename binPath to smartctlPath and replace hasSmartctl with smartctlPath checks

When reusing slices/structs with json.Unmarshal, fields marked with
omitzero that are missing in the JSON are not reset to zero - they
retain values from previous iterations.
This caused containers without bandwidth data to inherit values from
other containers that happened to occupy the same backing array
position in previous records, resulting in inflated 10m averages.
- Set containerStats to nil instead of [:0] to force fresh allocation
- Reset tempStats each iteration in AverageSystemStats
Changes container network statistics to use raw byte values instead of converting to megabytes agent-side, providing more accurate measurements for low-bandwidth containers. Maintains backward compatibility with older agents/hubs through fallback logic.
- Agent now sends Bandwidth field as [sent_bytes, recv_bytes] array
- Deprecated NetworkSent/NetworkRecv fields still populated for compatibility
- Hub and frontend fall back to deprecated fields when Bandwidth is zero
- Record averaging correctly handles both old and new formats
- TODO markers added for cleanup in version 0.19+
* feat: Added tooltips for navbar buttons to clear meaning of each one.
* update tooltips and fix linter errors

- Move SELinux context handling to internal/ghupdate for reuse
- Make chcon a true fallback (only runs if semanage/restorecon unavailable)
- Handle existing semanage rules with -m (modify) after -a (add) fails
- Apply SELinux handling to both agent and hub updates
- Add tests with proper skip behavior for SELinux systems

* feat: add ATA Device Statistics parsing and fall back for SMART temp reading
* simplify ata device statistics structs and fix smartctl args tests
* simplify ata device statistics lookup to use page number only

- Prefix Intel GPU ID as i0 to avoid NVML/NVIDIA index IDs like 0
- Update frontend GPU engines chart to select a GPU by id instead of
assuming g[0]
- Adjust tests to use the new Intel GPU id
purego requires dynamic linking, so split the agent builds:
- Default: static binary without NVML (works on musl/alpine)
- Glibc: dynamic binary with NVML support via purego
Changes:
- Add glibc build tag to conditionally include NVML code
- Add beszel-agent-linux-amd64-glibc build/archive in goreleaser
- Update ghupdate to use glibc binary on glibc systems
- Switch nvidia dockerfile to golang:bookworm with -tags glibc
