`CMSSW 4 2 8`: shall we use dots or otherwise standardise the version numbers?  Elsewhere we have:

```console
$ git grep -Hni 'CMSSW.4'
invenio_opendata/base/templates/get_started.html:71:                                            Note that in order to analyze CMS data collected in 2010, y n
eed <strong>CMSSW version 4.2.8 </strong>, supported only on <strong>Scientific Linux 5</strong>. The CMSSW command <kbd>cmsrel</kbd> you executed in the <a 
href="http://open-data.cern.ch/data/VMs#validate">validation stage</a> ensures that you have the right version running. Make sure you are always in the <stro
ng>CMSSW_4_2_8/src/</strong> directory by performing the <kbd>cd CMSSW_4_2_8/src/</kbd> every time you boot the VM and open the terminal.

ons in the WorkBook are in use in CMS currently and have been updated for more recent CMSSW releases. With the 2010 data, you should always use the releases 
in the series of CMSSW_4_2 and not higher. Also note that more recent code does not work with older releases, so whenever you see <kbd>git cms-addpkg&hellip;
</kbd> in the instruction, it is likely that code package this command adds does not work with the release you need. However, the material under the pages gi
ves you a good introduction to PAT.
