It's production ready and we highly recommend switching to it for improved query performance. [PR [3810](https://github.com/grafana/tempo/pull/3810)]
Upgrading to Tempo 2.6 modifies the Parquet block format.
Although you can use Tempo 2.6 with vParquet2 or vParquet3, you can only use Tempo 2.6 with vParquet3.
You don't need to do anything with Parquet to go from 2.5 to 2.6.
All of your old blocks remain vParquet3, which 2.6 reads.
Tempo 2.6 creates vParquet4 blocks by default, which enables the new TraceQL features.
Although you can use Tempo 2.6 with vParquet2 or vParquet3, you can only use vParquet4 with Tempo 2.6 and newer.
You can also use the `tempo-cli analyse blocks` command to query vParquet4 blocks. [PR 3868](https://github.com/grafana/tempo/pull/3868)].
Refer to the [Tempo CLI ](https://grafana.com/docs/tempo/next/operations/tempo_cli/#analyse-blocks)documentation for more information.
