  WARHAMMER 40,000 
  CODEX: CHAOS SPACE MARINES
  Official Update Version 1.0
  Although we strive to ensure that our rules are perfect, 
  sometimes mistakes do creep in, or the intent of a rule 
  isn’t as clear as it might be. These documents collect 
  amendments to the rules and present our responses to 
  players’ frequently asked questions. As they’re updated 
  regularly, each has a version number; when changes 
  are made, the version number will be updated, and any 
  changes from the previous version will be highlighted 
  in magenta. Where a version number has a letter, 
  e.g. 1.1a, this means it has had a local update, only in 
  that language, to clarify a translation issue or other 
  minor correction.
