One week from now, I should finally have time to join this migration effort.
@Itms, my initial plan was to focus on the SpiderMonkey update, but it seems you already have that on you TODO-list? I have to admit it’s good news for me, because I know nothing about SpiderMonkey and would have to learn everything from scratch. My goal was to ensure 0 A.D. relies on the current ESR release, or at least the previous one, I guess yours is similar?
Would you agree that the best way I could help would be to experiment with git submodules ? I have some experience with them, and more generally see myself as a skilled git user (I used it daily for more than 10 years, including in very tricky ways) so that might be the best way to spend my time on this migration.
I have been maintaining git forges for a long time too (mostly self-hosted GitLab), so if you need support on this front feel free to ping me.
