# Tenzir Node v4.6.4

## 🚀 Features

### Add a `duration` field to operator metrics

Dec 6, 2023 · [@dominiklohmann](https://github.com/dominiklohmann) · [#3713](https://github.com/tenzir/tenzir/pull/3713)

The `tenzir.metrics.operator` metric now contains an additional `duration` field with the timespan over which the metric was collected.

## 🔧 Changes

### Use systemd provided default paths if available

Dec 6, 2023 · [@tobim](https://github.com/tobim) · [#3714](https://github.com/tenzir/tenzir/pull/3714)

When selecting default paths, the `tenzir-node` will now respect the systemd-provided variables `STATE_DIRECTORY`, `CACHE_DIRECTORY` and `LOGS_DIRECTORY` before falling back to `$PWD/tenzir.db`.
