Are there any large Hack codebases I can explore?
I am interested to see how different from straight PHP it is.
Does anyone know if FB tracks changes to PHP so Hack is "up to date"?

Specifically they used [2] 'partial mode' since "this loosens several restrictions to ease migration"

[2] https://docs.hhvm.com/hack/source-code-fundamentals/program-...
EDIT: This would indicate that Hack may perhaps support standard PHP syntax but not the other way around.
EDIT: According to this [3] they are very compatible.

depends what you mean by 'large' - perhaps https://github.com/hhvm/user-documentation ?

No, for the most part, Hack no longer considers PHP 'upstream'. Exceptions are things like security fixes to extension functions, if that particular extension function was derived from PHP.
