For our book, I added support to draw nicer diagrams (with overlays on the arrows placed in exactly the right spot). I also changed the syntax highlighting so that we can generate custom attributed strings for certain parts. You can see both parts in action in this post.
We also finally moved into our new house! It’s not finished yet, so we had to already move between the two floors twice, but by next week we’ll (hopefully) have a finished kitchen, finished bathrooms and a ground floor that’s completely done.
