    14  The fourth major release of containerd comes 11 months after the previous
    15  major release and covers a period of both significant project growth and
    16  further stabilization. Similar to previous releases, the number of API changes
    17  are small and, as always, backwards compatible. The growing ecosystem of plugins
    18  and users have driven improvements to make containerd more configurable, usable,
    19  and pluggable. On Windows, this release brings a new runtime utilizing the shim
    20  API. For clients, there are many new features and improvements completely
    21  implemented in the client libraries without requiring daemon upgrade.
    22  
    23  ### Runtime
    24  * **New Windows V2 runtime using shim API.** Adds support for the Windows runtime shims in containerd. *NOTE: while containerd's runtime is stable in this release, running Windows containers are not yet fully supported until the [runhcs shim](https://github.com/microsoft/hcsshim/tree/master/cmd/containerd-shim-runhcs-v1) is fully supported.*
    25  * **Improvements to ttrpc.** For better daemon to shim communication (https://github.com/containerd/containerd/pull/3341)
    26  * **Removed experimental Windows V1 runtime**
    27  * **Update runc dependency** Updated runc for CVE-2019-16884
    28  
    29  ### Snapshots
    30  * **New Devmapper snapshotter** (https://github.com/containerd/containerd/pull/3022)
    31  * **Improved label support for plugins.** Allows snapshot plugins to use labels from clients for advanced use cases
    32  
    33  ### Plugins
    34  * **Support for plugins registering as a TCP service**
    35  * **Configurable plugin directory**
    36  * **Add stream processor plugin.** Allow handling of custom media types during unpack (https://github.com/containerd/containerd/pull/3482)
    37  
    38  ### Client
    39  * **Default handling from namespace labels.** Allows defaults to be configured per containerd namespace (https://github.com/containerd/containerd/pull/3403)
    40  * **Improved Docker resolver with mirroring support**
    41  * **Support for cross repository push** (https://github.com/containerd/containerd/pull/3218)
    42  
    43  ### API
    44  * **Add support for direct resource management in leases** (https://github.com/containerd/containerd/pull/3304)
    45  * **Add ttrpc service for shim event publishing**
    46  * **Add annotations to descriptors in API**
    47  * **Add id to TaskDelete event message to match exec id**
    48  * **Add payload parameter to apply in diff service API**
    49  
    50  ### CRI
    51  This version of containerd is validated against v1.16, but it is also compatible with Kubernetes v1.12+. (See [more details](https://github.com/containerd/cri#support-metrics) about support metrics)
    52  
    53  #### Features
    54  * **Supported per-pod containerd shim.** The `io.containerd.runc.v2` runtime is fully validated and ready to be used in production. This helps minimizing per-pod resource overhead. Note that `io.containerd.runtime.v1.linux` is still the default runtime. (https://github.com/containerd/cri/issues/1075)
    55  * **Added file-based generic runtime config options.** This will be used by out-of-tree runtimes like gvisor and kata (https://github.com/containerd/cri/pull/1029), e.g.
    56  ```
    57  [plugins.cri.containerd.runtimes.kata]
    58    runtime_type = "io.containerd.kata.v1"
    59  [plugins.cri.containerd.runtimes.kata.options]
    60    TypeUrl = "io.containerd.kata.v1.options"
    61    ConfigPath = "/etc/kata/config.toml"
    62  ```
    63  * **Added the `pod_annotations` runtime option.** Pod annotations specified in the list will be passed to the runtime as OCI annotations. This enables runtimes to support annotation-based experimental features. (https://github.com/containerd/cri/pull/1084)
    64  * **Added `stream_idle_time` option.** This makes idle connection timeout of the streaming server configurable. (https://github.com/containerd/cri/issues/1057)
    65  * **Added [traffic shaping pod annotations](https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/network-plugins/#support-traffic-shaping) support.** *NOTE: traffic shaping is still an experimental feature in Kubernetes.* (https://github.com/containerd/cri/issues/1150)
    66  * **Added `max_conf_num` option to `plugins.cri.cni`**. This makes it possible to setup multiple CNI networks in a pod. *NOTE: multi-network is not an officially supported feature in Kubernetes.*(https://github.com/containerd/cri/issues/1154)
    67  * **Added `plugins.cri.registry.configs` option to support TLS and auth configs of registries.** (https://github.com/containerd/cri/issues/1143) *NOTE: Non-mutual TLS is also supported. (https://github.com/containerd/containerd/issues/3521)* (see [registry.md](https://github.com/containerd/cri/blob/f1d492b0cdd14e76476ee4dd024696ce3634e501/docs/registry.md) for more details)
    68  * **Added tcp endpoint for CRI service.** The tcp service can be disabled with the `disable_tcp_service` option, and it is disabled by default. (https://github.com/containerd/cri/issues/1181)
    69  * **Added `max_concurrent_downloads` option to restrict the number of concurrent downloads for each image.** The default concurrency is `3`. (https://github.com/containerd/cri/pull/1211)
    70  * **Added `privileged_without_host_devices` runtime option to disable host devices for privileged pods for the runtime.** This is especially useful for runtimes like kata. (https://github.com/containerd/cri/issues/1213)
    71  * **Supported IPv4/IPv6 dualstack.** See Kubernetes [dual-stack doc](https://kubernetes.io/docs/concepts/services-networking/dual-stack) for more information. To enable dual-stack, your CNI plugin needs to support it. If you are using the CNI config template, see [how to configure it to support dual-stack](https://github.com/containerd/cri/blob/release/1.3/docs/config.md#cni-config-template).
    72  
    73  #### Enhancements
    74  * Avoided `Status` lockup when CNI network setup/teardown is slow. (https://github.com/containerd/cri/issues/1078)
    75  * Added CNI config in `Status` (`crictl info`) output. (https://github.com/containerd/cri/pull/1158)
    76  * Supported URL path in `plugins.cri.registry.mirrors`, e.g. `https://my.custom.registry/anypath`. (https://github.com/containerd/cri/pull/1227)
    77  * Added wildcard `*` support in `plugins.cri.registry.mirrors`. (https://github.com/containerd/cri/issues/1196)
    78  * Removed an unnecessary round-trip to the image registry when pulling image. (https://github.com/containerd/cri/issues/1229)
    79  * Updated cni library to v0.7.1 which has better context cancellation support. (https://github.com/containerd/cri/issues/1236)
    80  * Updated cni plugins to v0.7.6 to fix a race condition in the `bridge` plugin. (https://github.com/containerd/containerd/issues/3507)
    81  
    82  #### Deprecation
    83  * `ctr cri load` command is deprecated, use `ctr -n=k8s.io images import` instead.(https://github.com/containerd/cri/issues/909)
    84  * The `plugins.cri.containerd.default_runtime` option is deprecated, use `plugins."io.containerd.grpc.v1.cri".containerd.default_runtime_name` instead. (https://github.com/containerd/cri/issues/1076)
    85  * Runtime options including `systemd_cgroups`, `runtime_engine` and `runtime_root` are deprecated, use runtime `options` instead. (https://github.com/containerd/cri/pull/1217)
    86  * `runtimeHandler` field is moved from the sandbox `info` into `status`. (https://github.com/containerd/cri/pull/1063)
    87  * `plugins.cri.registry.auths` is deprecated, use `plugins.cri.registry.configs` instead. (https://github.com/containerd/cri/pull/1227)
    88  
    89  ### Other
    90  * **Support additional garbage collection labels.** Allows more advanced resource management use cases on the client
    91  * **Fix garbage collection scheduling on reference removal.** Ensures removal of leases or containers triggers the next scheduled garbage collection
