WARNING: After upgrading to Solr 10.1, downgrading to an earlier Solr 10.0.x version may fail because the older version does not include the `Lucene104` codec needed to read the newly written segments.
If you require the ability to roll back, back up your indexes before upgrading.

=== Docker

The `gosu` binary is no longer installed in the Solr Docker image. See https://github.com/tianon/gosu[gosu github page] for alternatives, such as `runuser`, `setpriv` or `chroot`.
