Problem with todonotes - "Unknown option 'textsize' "

Question

I'm writing a document with a5paper formatting (obtained through the geometry package). In particular this means that I have narrower margins.

I really like TikZ and especially todonotes. The problem is that the box is larger than the margin. To fix that, I used the option textwidth, and all went fine.

As a last thing, I'd like to be able to reduce the size of the text, so I can fit larger words in. The option textsize seems to be there just for this purpose: unfortunately it doesn't work for me.

Here is an example of code I tried

\documentclass{article}
\usepackage[textsize=tiny]{todonotes}
\begin{document}
  blah blah blah blah\todo{more grothendieck blah} whatever blah blah.
\end{document}

obtaining the following in the log file

/usr/local/texlive/2008/texmf-dist/tex/latex/todonotes/todonotes.sty:80: LaTeX 
Error: Unknown option `textsize' for package `todonotes'

I also tried to download the package from CTAN and to load it locally but I got the same message.

Am I doing something wrong? Should I be perhaps updating TeXlive or something?

Answer 1

Your example works fine with MikTeX 2.9 beta and TeXLive 2009/2010 (ref. Caramdirs comment), so an update of TeXLive should do the trick.

Answer 2

From reading the documentation, it looks like you want to use the option [size=\tiny].
