v4.0.0

Replaces legacy composer-based project creation setup tool with bash script which can be installed as a global for use in initial project setup.

Runs the same underlying WP CLI commands underneath as before, with some future placeholders for enhancing initial theme and plugin setup with configuration options.

Currently points at 'latest' Erebus code in master/main branch - will move this to versioned release tags once Erebus is updated.

New bash script was supported by Claude AI
