Highlights
Out-of-order (O3) performance is heavily reliant on correctly configured hysteresis values. In 6.0.0, it is very easy to reset these values to 0 with alter table statements, causing ingest performance degradation. This version address fragility of the settings by fixing bugs in all affected alter table variations.
Additionally we made an effort to make timestamp search more coherent. You will be able to search consistently on timestamp represented by string values.
