<!-- Please search existing work items before filing to avoid duplicates. --> ## Description This the is doc which needs to be follow: https://project.pages.drupalcode.org/ai/1.3.x/documentation/#how-do-you-switch-the-default-version-for-maintainers But while doing this, @a.dmitriiev discovered that it needs to be done over GitLab. So here is a task to figure out what needs to be done. ## Tasks <!-- List the concrete implementation steps — the what, not the why (that belongs in Description above). Each item should be independently completable and verifiable. Check items off as work progresses. --> * [ ] ## Acceptance criteria <!-- Define what "done" looks like. Each criterion should be independently verifiable. Example: - Site builders can configure X via the UI without writing code. - Existing behavior is unchanged when the new setting is left at its default. --> * ## Testing instructions *(added by implementor before review)* <!-- Testing Setup (optional — to verify on a clean install): mkdir my-drupal-site && cd my-drupal-site ddev config --project-type=drupal11 --docroot=web ddev composer create-project drupal/cms ddev drush site:install --account-name=admin --account-pass=admin -y # Enable AI Dashboard and ai_api_explorer # Launch the site and open the AI dashboard to add an OpenAI or Anthropic key: ddev launch $(ddev drush uli /admin/config/ai) --> 1. The documentation site should default to the 1.4.x branch code.
