There is a branch for r29 r29 branch. I have cleaned up and condensed files and more in the recent updates, both for 28 and 29. I would be glad to have your feedback
I took a look some time ago at the changes. They contain mostly single player optimizations. And beside some useful changes there are visual degradations.
Our repo contains a PR with more appropriate LLM changes here: https://gitea.wildfiregames.com/0ad/0ad/pulls/9257, but the generated code isn't in production ready state.
