Helm 2.1.0: Kube 1.5, Plugins, and Template Functions!

The Helm 2.1.0 is a feature release. We are excited to include Kubernetes 1.5 support, as well as several new and notable features. As we close out the 2016 year, we want to again take the opportunity to thank the nearly 100 people who have contributed code to Helm and to the Charts repo. We hope that with your collaboration, we can continue to craft a tool that is broadly useful to the Kubernetes community. - Join the discussion in [Kubernetes Slack](https://slack.k8s.io/): `#helm` - Hang out at the Public Developer Call: Thursday, 9:30 Pacific via [Zoom](https://engineyard.zoom.us/j/366425549) - Test, debug, and contribute charts: [GitHub/kubernetes/charts](https://github.com/kubernetes/charts) ## Notable Changes Since 2.0.2 - Kubernetes 1.5 support is included. Kubernetes 1.4 is still supported. - Helm charts can now annotate resources that should _not_ be deleted on `helm delete`. - Extend the Helm client behavior with Helm Plugins. You don't even have to know Go. Write them in whatever language you like. - Generate ConfigMaps and Secrets more easily with the improved `{{ .Files }}` object. - Use SemVer 2 ranges in `requirements.yaml` - And finally, get better error messages when chart errors occur. Version 2.1.0 is not ensured to be compatible with 2.0.2. We strongly recommend upgrading both client and server components. ## Installing and Updating Helm binaries: - [OSX](https://get.helm.sh/helm-v2.1.0-darwin-amd64.tar.gz) - [Linux](https://get.helm.sh/helm-v2.1.0-linux-amd64.tar.gz) - [Linux i386](https://get.helm.sh/helm-v2.1.0-linux-386.tar.gz) - [Windows](https://get.helm.sh/helm-v2.1.0-windows-amd64.zip) The [Quickstart Guide](https://github.com/kubernetes/helm/blob/master/docs/quickstart.md) will get you going from there. For **upgrade instructions** or detailed installation notes, check the [install guide](https://github.com/kubernetes/helm/blob/master/docs/install.md). You can also use a [script to install](https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get) on any system with `bash`. ## What Next? - 2.1.1 will be our next bugfix release. Bugfix releases will be made available as we find and fix issues. - 2.2.0 will be our next feature release. We are shooting for a February 2017 release. The 2.0.x line will _not_ be updated to the Kubernetes 1.5 library. Those wishing to stay on the Kubernetes 1.4 codebase may continue running Helm 2.0.2. That said, we have tested Helm 2.1.0 with Kubernetes 1.4 and have found no issues. ## All Changes Since 2.0.2 fix(glide): add assert library 575ed9a9d4fd760f3f9798127f6612e9fb133bd1 fix(deps): Adding missing test dependencies 4f096581d73dc31cc0ef1c107d25493d3f21e27d fix(semver): Ranges can fail with some pre-release numbering 8264d8ba0a0b2a55785aef123a2e9b9a57a16a95 fix(_): add support for "DELETING" status 936028f29aaf9e9de0e9f83949f3076a9c253da0 feat(helm): add newline to fetch --verify output 4dd77e774996ccf20d55f16eccb2a9c7de21a2fc feat(_): bump kubernetes to 1.5.0 c9783de15ce4330f8b7818aae06db04d3065bcb8 ref(kube): simplify encoding for creating patches 525df8f0d1caf1372b1001bf91f28395ebb79e24 test(kube): add test for upgrade fb9ef50bc8530968d86f150957c276fc6a92e1b8 feat(_): bump kubernetes to 1.5.0-beta.3 74361b1f3acb1655409093b2705df64418294f84 ref(kube): use a more specific interface for discovery client 7413320d2db9aa291c41f4c2c78ad2f76cd49ff6 ref(kube): isolate ensureNamespace and add tests cac9f9c7cc1e47024f5b69ee7a76634d8cf3c61c ref(kube): remove unused fields on client bceea66d278211e4a1dd3ccb40a774bd672cc59e fix(_): import grouping 84ae1268e19bf73ff9cad17d4f069a907c0f15ab ref(tiller): refactor clientset out of environment 7f44c116a1d75eec085af6bf4b6213ce43b2fdc7 feat(_): migrate to kubernetes 1.5 ea3be9e3b24191bdefabc87e8f2fe445d071c1f3 Set Helm deployment to pull IfNotPresent 989e59f5baeee984c2eb9e010d2c05552109021f feat(ci): add travis configuration bbe55f49fa24690d748b1a5ddd35599b67e1ef32 Include lines functions 1df13df88d80e7e90517d48918489050e24bb5d4 Add Lines method, remove path utils (Sprig pr) 6760aa15887b404305169fe1472de214a5a82b35 chore(_): bump go1.7.4 ee5454739db310648272b394dc70d9b49aa70051 update download links to v2.0.2 52f64f4542490d864884753c7e95491cd46d982e Fix erroneous import 5d58b7792c4b0b56ec8eee49cfcc79980e9b0ed3 Document ToYaml function 0474bcbcf1e11ca58c02b472a4facf1e5b1e745f Add documentation for imported golang.org/pkg/path funcs ec964ff41dc981d62f0ac0fa2308a3bc9143ac67 Add AsSecrets, AsConfig methods for Files object.
