ability to auto update sub-tasks when parent tasks change?

Raf

it seems like parent/child tasks are not linked in any meaningful way. if i set the parent tasks to complete this should mean that the child tasks are complete, or in testing. etc.

is it possible to cascade some changes to sub-tasks? if for example i want to move a parent to a different fix version, now i have to make this change on every sub task.

No, they're not linked automatically, because people have different needs for their interaction

Some don't need any updates, some need data to cascade down, others need it to roll up, some just need blocks on processes ("do not allow close of parent while sub-tasks are open, but don't touch data on other issues just because you've changed something on one issue", for example). There's no way to define a rule that would work for everyone, hence there's no way to code for it.

You'll need to find or write plugins that implement your particular business logic. There's quite a few in the marketplace, but frankly, use the "script runner" plugin. You'll need to learn a bit of coding and the Jira api, but the examples provided are really good, and you'll find your coding becomes copy and tweak (and, of course, trawl "answers" for code and ideas)
