v2.0.1

heroku/ruby

• Commons: Introduce build_output module (#155)
• Commons: Remove gem_list, rake_status, rake_task_detect modules (#155)
• Commons: EnvCommand removed, replaced with fun_run (#139)

v2.0.0

heroku/ruby

• Initial version of Ruby buildpack in Rust (#93)
• Version 2.0.0 for the first release is not a typo. There was an issue in pack where a builder with the same name and version number would reuse artifacts left on image from prior runs which caused issues. There were prior releases of heroku/ruby CNB from different sources that triggered this problem. To ensure no one would encounter that issue we developed and released using a version we know has not been used before. Version 2.0 was the first major version without a prior release of heroku/ruby CNB from any source.
