As of 2024-03-12:
- the whole Introduction and Essentials main chapter will be completely overhauled (highly improved chapter structure) and greatly extended
- 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
- the whole book will be proofread once again by another professional editor
- 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)
