The majority of Drupal for Humanists was written between January and May 2015. There's been a lot of changes to individual Drupal modules in the meantime, some of which affect the configuration described in the book. This page summarizes those changes, with links to more details in the affected chapters.

In general, you should only install modules from drupal.org. Stable module releases (i.e. those that don't have an "alpha" or "beta" appended to them) are monitored by the Drupal security team. For a module to be posted, it has to meet the Drupal coding standards. Neither of these is sufficient to guarantee that bad things won't happen when you install the module (including consequences potentially as bad as deleting things from your database), but that happens rarely.
