Quasar “Senaca” Beta 3.13.6 released

Monday November 28, 2022

This is the beta 3.13 branch, not to be confused with the stable 3.10 branch.

We are thrilled to announce the immediate availability of QuasarDB 3.13.6, a beta version update from 3.13.5.

This release has more than 40 improvements, fixes, and new features!

In particular, we’ve significantly improved the management of catastrophic events such as hard drive failures to reduce the probability of data loss.

The query language has some notable enhancements, and we added support for UPSERT, making Quasar capable of handling every possible data update scenario.

We hope we enjoy this new release very much!

The change log below has the complete list.

QuasarDB is also available on the AWS marketplace.

32-bit and 64-bit ARM binaries for Linux are now included with every release.
