XTDB 2.0 is Now Generally Available

What do the current XTDB across-time queries lack in this regard? I am under the impression that XTDB already supports what you're asking for, from the release notes:

> Full, across-time queries: using SQL:2011's bitemporal primitives and/or 'XTQL' to answer "what did we know, and when?".

> No history/audit tables, triggers required: use it as a regular update-in-place database (you're free to UPDATE and DELETE normally again!), safe in the knowledge that your history is there when you need it.

> Zero-cost, full database snapshots: immediately go back to any point in time without needing to schedule or store periodic snapshots/copies.
