[1/2] Just in case you use the units #TeXLaTeX package still somewhere within your documents (which always confuses me) you probably want to remove and replace it by #siunitx simple because that's the actively maintained one.
Joseph Wright is now talking about the last updates and plans for the package. The changes are much smaller than the complete reimplementation for v3.0.0 but he still is making the typesetting of numbers and units much easier.
Sitting before the 'proof' version #Springer sent me of my article.
What should I say. They butchered it. It's full of copy-paste-kinda errors. E.g., apparently they manually removed all of my #siunitx usage, removed spaces between numbers and units. There are even *typos in author names of citations*. How does that even happen, when it's #BibTeX generated!? Apparently they manually write it out somehow?
This is beyond me. 🤦
