Drupal core's issue thresholds are used to manage technical debt. During Drupal 8's development, feature completion and clean-up phases, the issue thresholds are:

(Earlier in the release cycle, Drupal 7 issues also counted toward Drupal 8 issue thresholds.)

When the issue thresholds are exceeded, core temporarily enters a period of restricted development:

  • New features will not be committed, since new features tend to add technical debt.
  • Relatively minor patches that touch a lot of files (e.g., coding standards clean-ups) will also not be committed until thresholds are met, to ensure that more urgent bug fixes are able to target a relatively stable code base.

As soon as issue counts are again under thresholds, these patches can be accepted again. This means that the best way to get a feature in is to help keep major and critical counts down.

For more information, see the explanation of the Drupal core release cycle and frequently asked questions.

API completion phase threshold reduction
During the API completion phase, the critical thresholds will be reduced week by week until they reach zero, as follows:
  • July 1: 14 critical bugs and tasks
  • July 8: 13 critical bugs and tasks
  • July 15: 12 critical bugs and tasks

Continuing on to...

  • September 2: 5 critical bugs and tasks
  • September 9: 4 critical bugs and tasks
  • September 16: 3 critical bugs and tasks
  • September 23: 2 critical bugs and tasks (DrupalCon Prague)
  • September 30+: 0 critical bugs and tasks

(There is no plan to reduce the thresholds for majors at this time.)
