As of 2023-10-12:
- the whole Introduction section will be completely overhauled (highly improved chapter structure) and probably greatly extended and generally improved, and will probably be renamed "Essentials"
- the whole book will be proofread again by another professional editor
- there will come a new major chapter with lots of content aimed at really clarifying any concepts that for many (or even most) readers prove to be too abstract to be fully (or even at all) understood otherwise
- all the architecture images will be replaced by quite photorealistic Blender renderings of fully remodeled scenes (which will also allow for the book to be sold commercially by publishing houses)
