I currently have a custom Drupal theme that is working well with Drupal 10.4.3. I am planning to upgrade to Drupal 11, as it appears to be the stable, long-term supported version.

What is the recommended process for upgrading a theme from Drupal 10.4.3 to Drupal 11?

For context, I previously migrated my site from Drupal 7 to Drupal 10. During that transition, I had to rewrite the theme from scratch due to major architectural changes. I am hoping that such a complete rewrite will not be necessary when upgrading from Drupal 10 to Drupal 11.

Any guidance or best practices would be appreciated.

As is all the rage right now (or maybe 2 months ago, I dunno anymore), I vibe-coded a benchmarking tool. It automatically creates verifiable tasks from core issues and crafts a few synthetic tasks from change records. It then asks the LLM to generate a patch to fix the issue after we've "unfixed" it in a docker container. Then we apply the LLM's patch and run relevant tests. If they pass, the task is considered completed successful.

The idea was to create a tool to measure how well open-weights LLMs know Drupal 11, so they don't get to use search or any tools. Gemini 3 Flash is just in there as reference. Currently, only core is covered, but I'm planning to expand to some of the major contrib modules like webform and paragraphs.

If you'd like me to test specific models, do let me know, preferably something that fits within my puny 4070's 12GB VRAM.

I used Nano Banana to generate a diagram of how it works.
