2.0.0-alpha.1 (2026-07-29)

⚠ BREAKING CHANGES

• LockResponse now carries its lock fields under a nested LockState message, and DetailsRequest.cmd is renamed to command.
• the -force flag is removed; use "dutctl unlock force" to break a lock held by another user.
• the version header is renamed from X-Dutctl-Version to Dutctl-Version and moved from internal/rpc to the new public pkg/headers. External clients must send and read the new name.
• The serial module's invocation changed. It no longer accepts a single optional expect regex; callers must pass an explicit step sequence. For example, serial "(?i)hello" becomes serial -- expect "(?i)hello". Existing configs/scripts using the old form must be updated.
• The main YAML config key on modules is replaced by passthrough. Existing config files must be updated.
• The dutagent configuration changed. Existing configurations must be updated in the following way: From commands: - name: example modules: - name: flash options: file: firmware.bin To commands: - name: example uses: - name: flash with: file: firmware.bin
• Flash module removed default tool. Users must now explicitly configure the tool option in their flash module configuration.
• The -v flag now enabled verbose output, while version information is printed with the 'dutctl version' command.
• The client does not add an extra newline to received Print messages anymore.
