I likely won’t change the cover.
I’m currently working on a second edition of “Adventures in Cybersecurity”. I’m going to hopefully make it a little better, as while I think it’s good, I think it could be better, too. It’s been out for nine months already(!) and re-reading it since then has made me think that I could do a couple of things differently, and also add in a bit more in the way of stories relevant to the title.
If you’ve purchased the book, I’ll refund your money if you purchase the second edition. I’ve never been one for charging for different editions of a book – I view them like software in that regard. Unless the product is materially different from the original, then I think you should get upgrades for free. 🙂
