Support syncing multiple major versions

[megawac]

Several projects maintain multiple major version (notably jQuery). It'd be useful to support syncing latest tags on different major versions

How would this be implemented? Something in the json? The only solution that I can think of that doesn't require manually enabling would be to pull in every release.

Nah, it shouldn't be too hard to determine when comparing local (jsdelivr) and remote versions; all that would have to be done would be to divy up versions by major and detect local major versions which aren't hosted. If any, open a PR.

Probably would make sense to only open 1 PR per project at a time.

What about systems that support, for example, 1.8.x and 1.9.x? This seems like it's going to fix jQuery (important, admittedly) but not much else.
