🐛 Fixes

  • Symbol list refactor (#796)
  • Fixed aggregation on sparse grouping columns (#1068).
    Depending on timestamps being accurate in the symbol list has proved to be troublesome. Instead, we should use the most recent version id known to a client as an indication of the client's view of the world at the time as symbol list entry is written. That way, we can identify and correct symbol list entries that refer to conflicting writes.
