Why haven't you mentioned Drupal 9? As of December 2021 I've updated most of the sites I look after to Drupal 9 (experience: mixed). I haven't decided how to label future version compatibility as D10 will be coming soon as well. The upgrade_status module is superb. You're bound to have issues with composer. Also watch out for a nasty session headers bug with redirect_after_login.

This module logs events and sends them to Sentry.  Sentry is an open source application you can self-install, but also a free/paid SaaS version.

For a content management framework as complex as Drupal it's worth logging errors.


  • In Raven config, recommend not logging debug and info messages, but do select Enable fatal error handler and Enable stacktraces.
  • You can enable the javascript error handler as well, but personally I only use PHP.

Drupal benefits:

  • logs the Drupal uid
  • logs referrer URLs
  • you can tag versions (e.g. commits) as well as different environments
  • you get a full breakdown of AJAX requests
