The site is supposed to reflect what's in the latest stable release, not just the develop branch, for what it's worth.

I suspect a lot of these may have been "stealthily" added as part of some refactoring—I think @mvadari was working on unifying some of the ways we refer to and interact with ledger entries, so that might have added some things incidentally.

Also, vault is part of the Single Asset Vault (SAV) amendment that is not yet supported, so it won't be possible to use until a later release, so I expect the documentation for that one should be included in the Single Asset Vault preview and then added to the main site when SAV is part of a stable release.

Yeah, some of this was in XRPLF/rippled#5237, which hasn't been released yet. That is also likely why Clio doesn't support it yet.
