v3.0-a.4

This is an early alpha release intended primarily for testing and packaging purposes.

A large number of internal changes have been made, including improvements to error handling, updates to message marshaling, and significant code movement from nvme-cli into libnvme. The list of changes is extensive and mostly internal, which means there is a higher likelihood of regressions or overlooked issues.

These alpha releases are meant to help identify bugs, integration issues, and other mistakes early.

Who should use this release

Developers working with nvme-cli/libnvme

Note: This version is not recommended for production use.
