Consequences

– “It’s done when it’s done” meant no one knew when to

expect new features / plan for migrations

– Little incentive for funded core dev = burnout

–Coupling new features with backwards compatibility breaks

limited innovation in core product

– “We’ll break your code, not your data” = people often stayed

on release until EOL, then faced painful upgrade path

Introducing “LTS” releases / “security fixes only” stage


Innovation through “experimental” modules

Benefits

– Predictable release schedule that both end users and core

developers can plan and organize around.

– Site builders can acquire powerful new functionality without

reinventing site.

– Opportunities to get end-user feedback and evolve features

over time (vs. being “stuck” with whatever shipped in 8.0.0).

– Drupal 9 becomes just a normal “minor” release, with

backwards-compatibility layers dropped.

But I’m still on Drupal 7!


If it’s working for you, that’s fine! (Until Drupal 9.)

But if D8 offers features you want, consider earlier adoption.


Monitor the contributed modules you need.
