 ### Breaking Changes

 - new syntax for nodefilters
@ -69,7 +15,6 @@ The demo repository has also been updated to work with k3d v5: <https://github.c
  - the `--port` flag has the `proxy` opt (see new nodefilter syntax above) set by default
  - to leverage the old behavior of direct port-mappings, use the `direct` opt on the port flag
  - the nodefilter `loadbalancer` will now do the same as `servers:*;agents:*` (proxied via the loadbalancer)
- flag `--registries-create` transformed from bool flag to string flag: let's you define the name and port-binding of the newly created registry, e.g. `--registry-create myregistry.localhost:5001`

 ### Fixes

@ -86,7 +31,6 @@ The demo repository has also been updated to work with k3d v5: <https://github.c
  - updated fork of `confd` to make usage of the file backend including a file watcher for auto-reloads
    - this also checks the config before applying it, so the lb doesn't crash on a faulty config
  - updating the loadbalancer writes the new config file and also checks if everything's going fine afterwards
-  - some settings of the loadbalancer can now be configured using `--lb-config-override`, see docs at <https://k3d.io/v5.0.0/design/defaults/#k3d-loadbalancer>
 - helper images can now be set explicitly via environment variables: `K3D_IMAGE_LOADBALANCER` & `K3D_IMAGE_TOOLS` (#638)
 - concurrently add new nodes to an existing cluster (remove some dumb code) (#640)
  - `--wait` is now the default for `k3d node create`
@ -108,7 +52,6 @@ The demo repository has also been updated to work with k3d v5: <https://github.c
  - new config path `options.k3s.extraArgs`
 - config file: environment variables (`$VAR`, `${VAR}` will be expanded unconditionally) (#643)
 - docker context support (#601, @developer-guy & #674)
- Feature flag using the environment variable `K3D_FIX_DNS` and setting it to a true value (e.g. `export K3D_FIX_DNS=1`) to forward DNS queries to your local machine, e.g. to use your local company DNS

 ### Misc

@ -116,28 +59,6 @@ The demo repository has also been updated to work with k3d v5: <https://github.c
 - logs: really final output when creating/deleting nodes (so far, we were not outputting a final success message and the process was still doing stuff) (#640)
 - tests/e2e: add tests for v1alpha2 to v1alpha3 migration
 - docs: use v1alpha3 config version
- docs: update general appearance and cleanup
-
-## v4.4.8
-
-## Enhancements
-
- Improved DroneCI Pipeline for Multiarch Images and SemVer Tags (#712)
-  - **Important**: New images will not have the `v` prefix in the tag anymore!
-    - but now real releases will use the "hierarchical" SemVer tags, so you could e.g. subscribe to rancher/k3d-proxy:4 to get v4.x.x images for the proxy container
-
-## Fixes
-
- clusterCreate: do not override hostIP if hostPort is missing (#693, @lukaszo)
- imageImport: import all listed images, not only the first one (#701, @mszostok)
- clusterCreate: when memory constraints are set, only pull the image used for checking the edac folder, if it's not present on the machine
- fix: update k3d-tools dependencies and use API Version Negotiation, so it still works with older versions of the Docker Engine (#679)
-
-### Misc
-
- install script: add darwin/arm64 support (#676, @colelawrence)
- docs: fix go install command (#677, @Rots)
- docs: add project overview (<https://k3d.io/internals/project/>) (#680)

-## k3d reserved settings
-
-When you create a K3s cluster in Docker using k3d, we make use of some K3s configuration options, making them "reserved" for k3d.
-This means, that overriding those options with your own may break the cluster setup.
-
-### Environment Variables
-
-The following K3s environment variables are used to configure the cluster:
-
-| Variable | K3d Default | Configurable? |
-|----------|-------------|---------------|
-| `K3S_URL`| `https://$CLUSTERNAME-server-0:6443` | no |
-| `K3S_TOKEN`| random | yes (`--token`) |
-| `K3S_KUBECONFIG_OUTPUT`| `/output/kubeconfig.yaml` | no |
-
-## k3d Loadbalancer
-
-By default, k3d creates an Nginx loadbalancer alongside the clusters it creates to handle the port-forwarding.
-The loadbalancer can partly be configured using k3d-defined settings.
-
-| Nginx setting | k3d default | k3d setting |
-|-------------|-------------|-------------|
-| `proxy_timeout` (default for all server stanzas) | `600` (s) | `settings.defaultProxyTimeout` |  |
-|`worker_connections` | `1024` | `settings.workerConnections` |
-
-### Overrides
-
- Example via CLI: `k3d cluster create --lb-config-override settings.defaultProxyTimeout=900`
- Example via Config File:
-
-  ```yaml
-  # ... truncated ...
-  k3d:
-    loadbalancer:
-      configOverrides:
-        - settings.workerConnections=2048
-  ```
-
-## Multiple server nodes
-
- by default, when `--server` > 1 and no `--datastore-x` option is set, the first server node (server-0) will be the initializing server node
-  - the initializing server node will have the `--cluster-init` flag appended
-  - all other server nodes will refer to the initializing server node via `--server https://<init-node>:6443`
-
-## API-Ports
-
- by default, we expose the API-Port (`6443`) by forwarding traffic from the default server loadbalancer (nginx container) to the server node(s)
- port `6443` of the loadbalancer is then mapped to a specific (`--api-port` flag) or a random (default) port on the host system
-
-## Kubeconfig
-
- if `--kubeconfig-update-default` is set, we use the default loading rules to get the default kubeconfig:
-  - First: kubeconfig specified via the KUBECONFIG environment variable (error out if multiple are specified)
-  - Second: default kubeconfig in home directory (e.g. `$HOME/.kube/config`)
-
-## Networking
-
- [by default, k3d creates a new (docker) network for every cluster](./networking)

 - The Problem: Passing a feature flag to the Kubernetes API Server running inside k3s.

-## What is k3d?
+**This page is targeting k3d v4.0.0 and newer!**

 k3d is a lightweight wrapper to run [k3s](https://github.com/rancher/k3s) (Rancher Lab's minimal Kubernetes distribution) in docker.

 k3d makes it very easy to create single- and multi-node [k3s](https://github.com/rancher/k3s) clusters in docker, e.g. for local development on Kubernetes.

-**Note:** k3d is a **community-driven project**, that is supported by Rancher (SUSE) and it's not an official Rancher (SUSE) project.

 ## Registries configuration file

 You can add registries by specifying them in a `registries.yaml` and referencing it at creation time:
 `#!bash k3d cluster create mycluster --registry-config "/home/YOU/my-registries.yaml"`.

+??? Tip "Pre v4.0.0 solution"
+    Before we added the `--registry-config` flag in k3d v4.0.0, you had to bind-mount the file to the correct location: `--volume "/home/YOU/my-registries.yaml:/etc/rancher/k3s/registries.yaml"`

 ### Using k3d-managed registries

+!!! info "Just ported!"
+      The k3d-managed registry is available again as of k3d v4.0.0 (January 2021)

 #### Create a dedicated registry together with your cluster

-1. `#!bash k3d cluster create mycluster --registry-create mycluster-registry`: This creates your cluster `mycluster` together with a registry container called `mycluster-registry`
+1. `#!bash k3d cluster create mycluster --registry-create`: This creates your cluster `mycluster` together with a registry container called `k3d-mycluster-registry`

  - k3d sets everything up in the cluster for containerd to be able to pull images from that registry (using the `registries.yaml` file)
  - the port, which the registry is listening on will be mapped to a random port on your host system

-2. Check the k3d command output or `#!bash docker ps -f name=mycluster-registry` to find the exposed port (let's use `12345` here)
-3. Pull some image (optional) `#!bash docker pull alpine:latest`, re-tag it to reference your newly created registry `#!bash docker tag alpine:latest mycluster-registry:12345/testimage:local` and push it `#!bash docker push mycluster-registry:12345/testimage:local`
-4. Use kubectl to create a new pod in your cluster using that image to see, if the cluster can pull from the new registry: `#!bash kubectl run --image mycluster-registry:12345/testimage:local testimage --command -- tail -f /dev/null` (creates a container that will not do anything but keep on running)

 #### Create a customized k3d-managed registry

 1. `#!bash k3d registry create myregistry.localhost --port 12345` creates a new registry called `k3d-myregistry.localhost` (could be used with automatic resolution of `*.localhost`, see next section - also, **note the `k3d-` prefix** that k3d adds to all resources it creates)
-2. `#!bash k3d cluster create newcluster --registry-use k3d-myregistry.localhost:12345` (make sure you use the **`k3d-` prefix** here) creates a new cluster set up to use that registry
+2. `#!bash k3d cluster create newcluster --registry-use k3d-myregistry.localhost:12345` (make sure you use the **`k3d-` prefix** here) creates a new cluster set up to us that registry
