## stable-2.13.6
This stable release fixes a regression introduced in stable-2.13.0 which
resulted in proxies shedding load too aggressively while under moderate request
load to a single service ([#11055]). In addition, it updates the base image for
the `linkerd-cni` initcontainer to resolve a CVE in `libdb` ([#11196]), fixes a
race condition in the Destination controller that could cause it to crash
([#11163]), as well as fixing a number of other issues.
* Control Plane
* Fixed a race condition in the destination controller that could cause it to
panic ([#11169]; fixes [#11163])
* Improved the granularity of logging levels in the control plane ([#11147])
* Proxy
* Changed the default HTTP request queue capacities for the inbound and
outbound proxies back to 10,000 requests ([#11198]; fixes [#11055])
* CLI
* Updated extension CLI commands to prefer the `--registry` flag over the
`LINKERD_DOCKER_REGISTRY` environment variable, making the precedence more
consistent (thanks @harsh020!) (see [#11144])
* CNI
* Updated `linkerd-cni` base image to resolve [CVE-2019-8457] in `libdb`
([#11196])
* Changed the CNI plugin installer to always run in 'chained' mode; the plugin
will now wait until another CNI plugin is installed before appending its
configuration ([#10849])
* Removed `hostNetwork: true` from linkerd-cni Helm chart templates
([#11158]; fixes [#11141]) (thanks @abhijeetgauravm!)
* Multicluster
* Fixed the `linkerd multicluster check` command failing in the presence of
lots of mirrored services ([#10764])
