## Source excerpt

This article is a mirror of the original announcement Today, SIG etcd is releasing etcd v3.7.0, the latest minor release of the popular distributed key-value store and core Kubernetes component. v3.7 ships the long-requested RangeStream feature, delivers several other performance improvements, removes the last remnants of the legacy v2store, and completes a major protobuf overhaul. You can download etcd v3.7.0 here: Source code Binaries Official container images This release also includes new versions of the two core etcd dependencies, bbolt v1.5.0 and raft v3.7.0. For instructions on installing etcd, see the install documentation. For the full list of changes, see the etcd v3.7 changelog. A heartfelt thank you to all the contributors who made this release possible! Major features The most significant changes in v3.7.0 include: RangeStream -- stream large result sets in chunks instead of buffering the whole response. Keys-only range requests, faster and more reliable leases, and several other performance improvements. etcd now boots entirely from v3store, eliminating a long-standing dependency on the legacy v2 store A completed protobuf overhaul, replacing outdated protobuf libraries with fully supported ones. etcd v3.7 ships with bbolt v1.5.1 and raft v3.7.0. FeaturesRangeStream In etcd v3.6 and earlier, it is challenging to work with requests that return large result sets. The database would buffer the full result set before sending, leading to unpredictable latency and memory usage, both on the server and the client. The RangeStream RPC lets calling applications accept result sets in chunks, reducing latency and making buffering memory usage more predictable. Instructions on how to use RangeStream in gRPC calls and in etcdctl can be found in the etcd documentation. Users should try it out for their own applications. In coordinated releases, the RangeStream feature will become available to users running the upcoming v1.37 of Kubernetes by enabling the EtcdRangeStre
