## Breaking Changes & Deprecations

## New Features
- Moving to Kubernetes 1.6 means we had to add some extra build steps to `make bootstrap`. You cannot currently simply `glide install`. On rare occasions, rebuilding from source may first require deleting your `vendor/` folder and then running `make bootstrap`.
- The TLS client auth policy introduced in 2.3 has improved.
- New Helm template function: `merge` (with Sprig 2.11.0)
- Now we have zsh completion!!! Use `helm completion zsh` for zsh and `helm completion bash` for bash.
- New locking on release objects has been introduced.
- The `get` script for installing Helm has been improved
