+  * Google Cloud API implements `min_cpu_platform` to mean "use exactly this CPU". Revert [#405](https://github.com/poseidon/typhoon/pull/405) added in v1.13.4.
+  * Fix error creating clusters in new regions without Haswell (e.g. europe-west2) ([#438](https://github.com/poseidon/typhoon/issues/438))
+
+#### Addons
+
+* Update Prometheus from v2.8.0 to v2.8.1

+## v1.13.5
+
+* Kubernetes [v1.13.5](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1135)
+* Resolve in-addr.arpa reverse DNS lookups (PTR) for pod IPv4 addresses ([#415](https://github.com/poseidon/typhoon/pull/415))
+  * Reverse DNS lookups for service IPv4 addresses unchanged
+* Upgrade Calico from v3.5.2 to [v3.6.0](https://docs.projectcalico.org/v3.6/release-notes/) ([#430](https://github.com/poseidon/typhoon/pull/430))
+  * Change pod IPAM from `host-local` to `calico-ipam`. `pod_cidr` is still divided into `/24` subnets per node, but managed as `ippools` and `ipamblocks`
+* Recommend updating [terraform-provider-ct](https://github.com/poseidon/terraform-provider-ct) from v0.3.0 to [v0.3.1](https://github.com/poseidon/terraform-provider-ct/releases/tag/v0.3.1) ([#434](https://github.com/poseidon/typhoon/pull/434))
+* Announce: Fedora Atomic modules will be not be updated beyond Kubernetes v1.13.x ([#437](https://github.com/poseidon/typhoon/pull/437))
+  * Thank you Project Atomic team and users, please see the deprecation [notice](https://typhoon.psdn.io/announce/#march-27-2019)
+
+#### AWS
+
+* Support `terraform-provider-aws` v2.0+ ([#419](https://github.com/poseidon/typhoon/pull/419))
+
+#### Bare-Metal
+
+* Change the default iPXE kernel and initrd download protocol from HTTP to HTTPS ([#420](https://github.com/poseidon/typhoon/pull/420))
+  * Require an iPXE-enabled network boot environment with support for TLS downloads. PXE clients must chainload to iPXE firmware compiled with `DOWNLOAD_PROTO_HTTPS` [enabled](https://ipxe.org/crypto). (**action required**)
+  * Only affects Container Linux and Flatcar Linux install profiles that pull public images (default)
+  * Add `download_protocol` variable. Recognizing boot firmware TLS support is difficult in some environments, set the protocol to "http" for the old behavior (discouraged)
+
+#### DigitalOcean
+
+* Fix kubelet hostname-override to set node metadata InternalIP correctly ([#424](https://github.com/poseidon/typhoon/issues/424))
+  * Uniquely, DigitalOcean does not resolve hostnames to instance private IPs. Kubelet auto-detect mechanisms require the internal IP be set directly.
+  * Regressed in v1.12.3 ([#337](https://github.com/poseidon/typhoon/pull/337)) which aimed to provide friendly hostname-based node names on DigitalOcean

+  * Add liveness and readiness probes
+  * Refresh dashboards and organize to stay below ConfigMap size limit ([#426](https://github.com/poseidon/typhoon/pull/426))
+* Remove heapster manifests from addons ([#427](https://github.com/poseidon/typhoon/pull/427))
+  * Heapster addon powers `kubectl top` (in early Kubernetes, running the addon was expected). Today, there are better monitoring options.
+  * `kubectl top` reliance on a non-core extension means its not in-scope for minimal Kubernetes
+  * Look to prior releases if you still wish to apply heapster
+
+## v1.13.4
+
+* Kubernetes [v1.13.4](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1134)

+  * Require `terraform-provider-google` v1.19+ (**action required**)
+* Set the minimum CPU platform to Intel Haswell ([#405](https://github.com/poseidon/typhoon/pull/405))
+  * Haswell or better is available in every zone (no price change)
+  * A few zones still default to Sandy/Ivy Bridge (shifts in April 2019)
+
+#### Addons
+
+* Modernize Prometheus rules and alerts ([#404](https://github.com/poseidon/typhoon/pull/404))

+* Update nginx-ingress from v0.22.0 to v0.23.0
+  * Raise nginx-ingress liveness/readiness timeout to 5 seconds
+  * Remove nginx-ingess default-backend ([#401](https://github.com/poseidon/typhoon/pull/401))
+

+* Build Kubelet [system container](https://github.com/poseidon/system-containers) with buildah. The image is an OCI format and slightly larger.
+
+## v1.13.3
+
+* Kubernetes [v1.13.3](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.13.md#v1133)
+* Update etcd from v3.3.10 to [v3.3.11](https://github.com/etcd-io/etcd/blob/master/CHANGELOG-3.3.md#v3311-2019-1-11)

+* Reduce pod eviction timeout for deleting pods on unready nodes to 1 minute
+  * Respond more quickly to node preemption (previously 5 minutes)
+* Fix automatic worker deletion on shutdown for cloud platforms
+  * Lowering Kubelet privileges in [#372](https://github.com/poseidon/typhoon/pull/372) dropped a needed node deletion authorization. Scale-in due to manual terraform apply (any cloud), AWS spot termination, or Azure low priority deletion left old nodes registered, requiring manual deletion (`kubectl delete node name`)
+
+#### AWS
+
+* Add `ingress_zone_id` output with the NLB DNS name's Route53 zone for use in alias records ([#380](https://github.com/poseidon/typhoon/pull/380))

+
+#### AWS
+
+* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))
+* Combine apiserver and ingress NLBs ([#249](https://github.com/poseidon/typhoon/pull/249))
+  * Reduce cost by ~$18/month per cluster. Typhoon AWS clusters now use one network load balancer.
+  * Ingress addon users may keep using CNAME records to the `ingress_dns_name` module output (few million RPS)

+
+#### Bare-Metal
+
+* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))
+  * Users who exposed kube-apiserver on a WAN via their router/load-balancer will need to adjust its configuration (e.g. DNAT 6443). Most apiservers are on a LAN (internal, VPN-only, etc) so if you didn't specially configure network gear for 443, no change is needed. (possible action required)
+* Fix possible deadlock when provisioning clusters larger than 10 nodes ([#244](https://github.com/poseidon/typhoon/pull/244)) 
+
+#### DigitalOcean
+
+* Switch `kube-apiserver` port from 443 to 6443 ([#248](https://github.com/poseidon/typhoon/pull/248))

+
+#### Google Cloud
+
+* Use global HTTP and TCP proxy load balancing for Kubernetes Ingress ([#252](https://github.com/poseidon/typhoon/pull/252))
+  * Switch Ingress from regional network load balancers to global HTTP/TCP Proxy load balancing
+  * Reduce cost by ~$19/month per cluster. Google bills the first 5 global and regional forwarding rules separately. Typhoon clusters now use 3 global and 0 regional forwarding rules.
+* Worker pools no longer include an extraneous load balancer. Remove worker module's `ingress_static_ip` output
+* Allow using nginx-ingress addon on Fedora Atomic clusters ([#200](https://github.com/poseidon/typhoon/issues/200))
+* Add `worker_instance_group` module output to allow custom global load balancing
+* Add `instance_group` worker module output to allow custom global load balancing
+* Deprecate `ingress_static_ip` module output. Add `ingress_static_ipv4` module output instead.
+* Deprecate `controllers_ipv4_public` module output
+
+#### Addons
+
+* Update CLUO from v0.6.0 to v0.7.0 ([#242](https://github.com/poseidon/typhoon/pull/242))
+* Update Prometheus from v2.3.0 to v2.3.1
+* Update Grafana from 5.1.3 to 5.1.4
+* Drop `hostNetwork` from nginx-ingress addon
+  * Both flannel and Calico support host port via `portmap`
+  * Allows writing NetworkPolicies that reference ingress pods in `from` or `to`. HostNetwork pods were difficult to write network policy for since they could circumvent the CNI network to communicate with pods on the same node.
+
+## v1.10.4
+
+* Kubernetes [v1.10.4](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#v1104)

+  * Use Calico's default "first-found" to support single NIC and bonded NIC nodes 
+  * Allow [alternative](https://docs.projectcalico.org/v3.1/reference/node/configuration#ip-autodetection-methods) methods for multi NIC nodes, like can-reach=IP or interface=REGEX
+* Deprecate `container_linux_oem` variable
+
+#### DigitalOcean
+
+* Update Fedora Atomic module to use Fedora Atomic 28 ([#225](https://github.com/poseidon/typhoon/pull/225))
+  * Fedora Atomic 27 images disappeared from DigitalOcean and forced this early update
+
+#### Addons
+
+* Fix Prometheus data directory location ([#203](https://github.com/poseidon/typhoon/pull/203))
+* Configure Prometheus to scrape Kubelets directly with bearer token auth instead of proxying through the apiserver ([#217](https://github.com/poseidon/typhoon/pull/217))

+# Typhoon <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo.png">
+
+Typhoon is a minimal and free Kubernetes distribution.
+
+* Minimal, stable base Kubernetes distribution
+* Declarative infrastructure and configuration
+* Free (freedom and cost) and privacy-respecting
+* Practical for labs, datacenters, and clouds
+
+Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
+
+## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
+
+* Kubernetes v1.14.3 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
+* Single or multi-master, [flannel](https://github.com/coreos/flannel) networking
+* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled
+* Advanced features like [worker pools](https://typhoon.psdn.io/advanced/worker-pools/), [low-priority](https://typhoon.psdn.io/cl/azure/#low-priority) workers, and [snippets](https://typhoon.psdn.io/advanced/customization/#container-linux) customization
+* Ready for Ingress, Prometheus, Grafana, and other optional [addons](https://typhoon.psdn.io/addons/overview/)
+
+## Docs
+
+Please see the [official docs](https://typhoon.psdn.io) and the Azure [tutorial](https://typhoon.psdn.io/cl/azure/).
