v3.8.0

=====================================================================

--- Changes ------------------------------

- kubectl driver updates; getting better, but still need to fix
  autocomplete in certain circumstances

- added -y|--yes flags to scwrypts to auto-accept user-prompts (use with
  caution)

- figured out the whole mikefarah/yq vs kislyuk/yq thing; use YQ for
  compatiblity

--- Bug fixes ----------------------------

- helm template generation now loads values in a more appropriate order
  which prevents overwrite by the wrong values file

 - User yes/no prompts will **always be YES**
 - Other user input will default to an empty string
 - Logs will not be captured
+- Setting the environment variable `SCWRYPTS_GROUP_LOADER__[a-z_]\+` will source the file indicated in the variable (this allows custom groups without needing to modify the `config.zsh` directly)

+# Kubernetes `kubectl` Helper Plugin
+
+Leverages a local `redis` application to quickly and easily set an alias `k` for `kubectl --context <some-context> --namespace <some-namespace>`.
+Much like scwrypts environments, `k` aliases are *only* shared amongst session with the same `SCWRYPTS_ENV` to prevent accidental cross-contamination.
+
+
+## Getting Started
+
+Enable the plugin in `~/.config/scwrypts/config.zsh` by adding `SCWRYPTS_PLUGIN_ENABLED__KUBECTL=1`.
+Use `k` as your new `kubectl` and checkout `k --help` and `k meta --help`.
