 The package requires LaTeX3 support as provided in the
 `l3kernel` and `l3packages` bundles. Both of these are available
 on [CTAN](http://www.ctan.org/) as ready-to-install zip files.
-Suitable versions are available in MiKTeX 2.9 and TeX Live 2012
+Suitable versions are available in MiKTeX 2.9 and TeX Live 2015
 (updating the relevant packages online may be necessary).
 LaTeX3, and so `siunitx`, requires the e-TeX extensions: these
 are available on all modern TeX systems.
