QuestDB 9.3.3 is here - and `HORIZON JOIN` is the headline. It is a new join type built for markout analysis: measure how prices evolve at specific time offsets after an event, in a single query. If you have been stitching this together with self-joins, window functions, and application logic, those days are over. Alongside `HORIZON JOIN`, we are shipping `twap()` for time-weighted averages, SQL-standard `WINDOW` definitions, JIT-compiled filters on ARM64, and major performance gains across Parquet I/O, parallel `GROUP BY`, and `UNION` queries.
