Terraform tool for fetching release metadata

Description

Welcome to the tfrelease repo. This Python command line utility fetches Terraform release metadata, filters releases based on query, generates release tags, and returns the results in your desired output format [text|json|yaml]. It was built with CI/CD in mind.
