The repo structure is still in progress. I originally uploaded the full source as release packages instead of pushing incremental commits, which is why the tags currently point to the same snapshot. Im reorganizing the repository so each version will have its own commit history and proper tagging.
The 6.1.5 release is built from the same code as the tag (nothing unpublished.)
And yes, Im the sole developer. I only use AI for explanations or debugging, not for generating code.
Im cleaning up the repo structure soon.
