release notes for edge-19.7.1 (linkerd#3031)


* CLI
  * Added more descriptive output to the `linkerd check` output for control
    plane ReplicaSet readiness
  * **Breaking change** Renamed `config.linkerd.io/debug` annotation to
    `config.linkerd.io/enable-debug-sidecar`, to match the
    `--enable-debug-sidecar` CLI flag that sets it
  * Fixed a bug in `linkerd edges` that caused incorrect identities to be
    displayed when requests were sent from two or more namespaces
* Controller
  * Added the `linkerd.io/control-plane-ns` label to the SMI Traffic Split CRD
* Proxy
  * Fixed proxied HTTP/2 connections returning 502 errors when the upstream
    connection is reset, rather than propagating the reset to the client
  * Changed the proxy to treat unexpected HTTP/2 frames as stream errors rather
    than connection errors

edge-19.6.4 (linkerd#3013)

## edge-19.6.4

This release adds support for the SMI [Traffic Split](https://github.com/deislabs/smi-spec/blob/master/traffic-split.md)
API. Creating a TrafficSplit resource will cause Linkerd to split traffic
between the specified backend services. Please see [the spec](https://github.com/deislabs/smi-spec/blob/master/traffic-split.md)
for more details.

* CLI
  * Added a check to `install` to prevent installing multiple control planes
    into different namespaces
  * Added support for passing a URL directly to `linkerd inject` (thanks
    @Pothulapati!)
  * Added the `--all-namespaces` flag to `linkerd edges`
* Controller
  * Added support for the SMI TrafficSplit API which allows users to define
    traffic splits in TrafficSplit custom resources
* Web UI
  * Improved UI for Edges table in dashboard by changing column names, adding a
    "Secured" icon and showing an empty Edges table in the case of no returned
    edges

Add release notes for edge-19.6.3 (linkerd#2985)

## edge-19.6.3

* CLI
  * Updated `linkerd check` to validate the caller can create
    `PodSecurityPolicy` resources
* Controller
  * Default the mutating and validating webhook configurations `sideEffects` 
    property to `None` to indicate that the webhooks have no side effects on
    other resources (thanks @Pothulapati!)
* Proxy
  * Added the `NET_RAW` capability to the proxy-init container to be compatible
    with `PodSecurityPolicy`s that use `drop: all`
  * Fixed the proxy rejecting HTTP2 requests that don't have an `:authority`
  * Improved idle service eviction to reduce resource consumption for clients
    that send requests to many services
* Web UI
  * Removed the "Debug" page from the Linkerd dashboard while the functionality
    of that page is being redesigned
  * Added an Edges table to the resource detail view that shows the source,
    destination name, and identity for proxied connections

Edge 19.6.1 release notes

## edge-19.6.1

    injected proxy-init container version
* Controller
  * Added multiple replicas for the `proxy-injector` and `sp-validator`

Stable 2.3.1 Release Notes (linkerd#2869)

This stable release adds a number of proxy stability improvements.

To install this release, run: `curl https://run.linkerd.io/install | sh`

**Special thanks to**: @zaharidichev and @11Takanori!

**Full release notes**:

* Proxy
  * Changed the proxy's routing behavior so that, when the control plane
    does not resolve a destination, the proxy forwards the request with minimal
    additional routing logic
  * Fixed a bug in the proxy's HPACK codec that could cause requests with
    very large header values to hang indefinitely
  * Replaced the fixed reconnect backoff with an exponential one (thanks,
    @zaharidichev!)
  * Fixed an issue where requests could be held indefinitely by the load balancer
  * Added a dispatch timeout that limits the amount of time a request can be
    buffered in the proxy
  * Removed the limit on the number of concurrently active service discovery
    queries to the destination service
  * Fixed an epoll notification issue that could cause excessive CPU usage
  * Added the ability to disable tap by setting an env var (thanks,
    @zaharidichev!)

Edge 19.5.4 Release Notes (linkerd#2872)

## edge-19.5.4

* CLI
  * Added a JSON option to the `linkerd edges` command so that output is
    scripting friendly and can be parsed easily (thanks @alenkacz!)
* Controller
  * **New** Control plane installations now generate a self-signed certificate
    and private key pair for each webhook, to prepare for future work to make
    the proxy injector and service profile validator HA
  * Added a debug container annotation, allowing the `--enable-debug-sidecar`
    flag to work when auto-injecting Linkerd proxies
* Proxy
  * Changed the proxy's routing behavior so that, when the control plane does
    not resolve a destination, the proxy forwards the request with minimal
    additional routing logic
  * Fixed a bug in the proxy's HPACK codec that could cause requests with very
    large header values to hang indefinitely
* Web UI
  * Removed the Authorities table and sidebar link from the dashboard to prepare
    for a new, improved dashboard view communicating authority data
* Internal
  * Modified the integration test for `linkerd upgrade` to test upgrading from
    the latest stable release instead of the latest edge, to reflect the typical
    use case
