IMPORTANT: No additional bug fixes or documentation updates will be released for this version. For the latest information, see the current release documentation.
As a general rule, you can upgrade between minor versions (for example, 7.x to 7.y, where x < y) by simply installing the new release and restarting Logstash. Logstash typically maintains backwards compatibility for configuration settings and exported fields. Please review the release notes for potential exceptions.
Upgrading between non-consecutive major versions (5.x to 7.x, for example) is not supported.
