The 3rd edition of my software design textbook is just out:
https://link.springer.com/book/10.1007/978-3-032-11821-9
I'm also updating the companion website with new and revised exercises and solutions:

BTW the text is 100% genuine. Not a single sentence was generated with AI, and this includes no autocomplete and no grammatical "suggestion". My only writing tool is the good ol' spellchecker.
