Why haven't you mentioned Drupal 9? As of February 2022 I've updated all 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.

What about sites still running Drupal 7? In short I still recommend leaving them on Drupal 7. Your decision is really if you will gain anything from Drupal 8/9 and for many then answer will be no, and one of the main hassles - apart from converting each content type one at a time, and setting up a new theme, will be recreating all your views by hand, as views can't be automatically upgraded.

"Essential"

Install the devel module first.  The profile is a toolbar at the bottom of the screen. Features:

  • useful shortcuts (e.g. clear cache)
  • view info about current user, their role and permissions
  • server HTTP response
  • cache, DB and DOM loading performance
  • memory use
  • which blocks and views have been loaded

Tip: there are further reports ("collectors") you can turn on in the module preferences, and there's a shortcut to these from the menu in the first icon (Drupal logo). The toolbar is only a summary, all icons are clickable to view a full report. Each report is saved in the DB for later reading.

This module was ported from Symfony
