### v0.19.1, 2023-9-

- Fix a health overestimation with OpenBook open orders

When bids or asks crossed the oracle price, the serum3 health would be
overestimated before.

Now we track an account's max bid and min ask in each market and use that
as a worst-case price. The tracking isn't perfect for technical reasons
(compute cost, no notifications on fill) but produces an upper bound on
bids (lower bound on asks) that is sufficient to make health not
overestimate.
