This release brings a much-wanted `test` command to support testing Tesseracts 🙂 There are also improvements on how some validation errors were being displayed, and we changed the way we dynamically set `/home` for whatever user is running a Tesseract so that it now works in more security-hardened environments as well.

## What’s Changed

### Features

- Add better validation errors (#471)
- Add new `test` command to `tesseract run` and `tesseract-runtime` to support regression testing (#411)

### Bug Fixes

- Use libnss\_wrapper instead of addmeplease to create a home for any uid:gid specified at runtime (#476)
