v0.9.7 (Mar 07, 2018)
Overview of changes
- Enables high data density by turning multi-level indexing on by default. This allows efficient queries even where there is a lot of data per node.
- Core performance fixes to run better on lightweight (2 vCPU) machines
- Better handling of huge io spikes. The scenario is having many more requests from the clients than what the database cluster can handle.
- Tuning the Redis query layer performance

v0.9.6 (Mar 01, 2018)
Overview of changes
- Support for using Kubernetes style cnames in YugaByte CQL client natively! The sample applications can easily be run as a Kubernetes service now.
- Lots of perf fixes for running YugaByte on machines with large number of CPUs.
- Added built-in time functions such as now(), totimestamp(), tounixtimestamp() and unixtimestampof().
- Support for high-performance batch transaction codepath with intra-batch dependencies.

0.9.5 (Feb 16, 2018)
Overview of changes
- Support for natively running YugaByte DB using Kubernetes StatefulSets! YugaByte DB now works in GKE as well.
- Distributed transactions supported at isolation level SNAPSHOT ISOLATION.
- HINCRBY support in Redis API.
- Defaults for CQL client driver switched to strong consistency.
- Lots of performance enhancements and fixes. Notably - lock free hybric clock implementation. New YugaByte perf report uploaded.
- Improved debuggability - added slow query logging for Redis.
- Overhauled the third party build system to make it more readable and easy to maintain.
Thanks
- @mchang31415 for reporting a number of perf issues.
- @praneeth-nimmagadda for reporting issues with the
