+* BUGFIX: [Single-node VictoriaTraces](https://docs.victoriametrics.com/victoriatraces/) and vtinsert in [VictoriaTraces cluster](https://docs.victoriametrics.com/victoriatraces/cluster/): Rename various [HTTP headers](https://docs.victoriametrics.com/victoriatraces/data-ingestion/#http-headers) prefix from `VL-` to `VT-`. These headers help with debugging and customizing stream fields. Thank @JayiceZ for [the pull request](https://github.com/VictoriaMetrics/VictoriaTraces/pull/56).
