# Tenzir Node v5.4.1

This release fixes a bug within the JSON printer that could lead to invalid JSON being produced, and also led to response timeouts when using the Tenzir Platform.

## 🐞 Bug Fixes

### Fixed invalid JSON for small numbers

Jun 13, 2025 · [@jachris](https://github.com/jachris) · [#5282](https://github.com/tenzir/tenzir/pull/5282)

Operators such as `write_json` previously emitted invalid JSON for small numbers. This also affected the Tenzir Platform as it invalidated some responses, which could lead to no data showing up in the Explorer.

### Incorrect values when charting

Jun 13, 2025 · [@raxyte](https://github.com/raxyte) · [#5281](https://github.com/tenzir/tenzir/pull/5281)

The charting operators did not update aggregations correctly, which resulted in out-of-sync or `null` values.
