## 1.7.0 2019-08-27
Linkerd 1.7.0 includes a number of memory leak fixes for Linkerd and its
underlying `grpc-runtime` module. This release includes improvements for
SNI-enabled TLS communication, support for streaming arbitrarily large HTTP
requests and responses in HTTP/1 and HTTP/2 as well an upgraded JDK for
improved Docker container support.

A special thank you to [Fantayeneh](https://github.com/fantayeneh) for their
awesome work on [#2315](https://github.com/linkerd/linkerd/pull/2315)

I might add a bit more context here about this change:

These parameters were primarily intended to limit the amount of memory Linkerd used when buffering requests. The streamAfterContentLengthKB parameter achieves this more efficiently by streaming large messages instead of buffering them.

options in favor of `streamAfterContentLengthKB`. These parameters were
primarily intended to limit the amount of memory Linkerd used when buffering
requests. The streamAfterContentLengthKB parameter achieves this more

* Consul
* Enables streaming in the HTTP client used in the `io.l5d.consul` namer
to allow for arbitrarily large responses from Consul
* Support for the inclusion of Consul response service and node metadata
in Namerd 'io.l5d.mesh and 'io.l5d.httpController' responses.
* Linkerd Configuration
* Introduces a router parameter called `maxCallDepth` that prevents unbounded
cyclic proxy request routing
* Adds support for limiting the maximum size of `l5d-err` header values by
using `maxErrResponseKB` in an HTTP router
* Fixes an issue were some `socketOptions` were being ignored when partially
configured
* TLS
* Fixes an issue where Linkerd can't connect to SNI servers that are addressed
via IPv4 and IPv6
* HTTP/2
* Fixes a number of direct and heap memory leaks in Linkerd's HTTP/2 module
* Fixes an issue causing users of `grpc-runtime` module to experience direct
memory leaks
* Updates Linkerd's JDK version for improved container support

## 1.6.4 2019-07-01
