"Wasm heap memory, per canister 4GiB" Or has it been increased?

https://internetcomputer.org/docs/building-apps/canister-management/resource-limits claims that

Wasm heap memory, per canister 4GiB

But isn’t WASM64 specifically to overcome this limit and create tera-sized canisters?

Is this limit value outdated?

Currently, the available WASM size is 6 GB, but I think this applies when compiling to wasm64 rather than wasm32. I haven’t used this feature yet.
