v0.6.4

Date: 2026-10-21
Previous release: v0.6.3

Summary

An unknown subcommand of client or server given together with a flag is reported as the unknown command it is, with suggestions, instead of as an unknown flag.

Fixed

• Unknown subcommand with a flag: dnp3ctl client nope --format json (or any flag after an unknown subcommand) reported unknown flag: --format: Cobra stops at the client group, which has none of its subcommands' flags. It now reports unknown command "nope" for "dnp3ctl client", with "Did you mean this?" suggestions for a misspelt one (client pol → poll), as text or as the JSON error object. Without flags the message was already right. Exit code 2 as before.

Upgrade notes

• No breaking changes.
