Release Notes Template

Based off https://palantir.quip.com/pzRwAVr1bpzf

Pro-tip: look through the github diff between the previous release to see what's changed. The commit titles should give an outline of what's happened.

Upgrade Steps

List out, as concretely as possible, any steps users have to take when they upgrade beyond just dumping the dependency.
Write pseudocode that highlights what code should change and how.

$ terraform workspace new staging   
Created and switched to workspace "staging"!

You're now on a new, empty workspace. Workspaces isolate their state,
so if you run "terraform plan" Terraform will not see any existing state
for this configuration.

Installation: 1- Explain how Go path works? 2- What are the benefits of Go Module (reference its commands)?
Concurrency: 1- Explain Concurrency & when to use it? 2- How would you allow communication between goroutines in Go? 3- How would you manage their access to resources?

why do you use Go (my answer was as simple as "why i shouldn't", and some extra points Grimacing face)

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27
