Quasar “Seneca” 3.13.2 Beta Released
This is the beta 3.13 branch, not to be confused with the stable 3.10 branch.
We are very happy to announce the immediate availability of QuasarDB 3.13.2, a beta version update from 3.13.1.
This release brings important performance improvements across the board, and bring major new features such as a brand new low-latency, high-performance, cryptocurrencies exchange feed handler, support for EMA and MACD, and support for Apache Arrow as input and output.
Last but not least, real-time order book reconstruction is now out of private beta and available in this release, directly from the query language.
