I've spent the last few weeks finalizing the book and making the final edits – which turned out to be more than expected. Entire paragraphs have been completely rewritten for better clarity (I hope!), and a couple random tables have been expanded with a few new entries.
Despite having suffered not one, but two hard-drive crashes since we launched this project (another reminder to always make backups!), we didn't lose any data and we are still on track to release this book very soon...
