Semantic-release

As explained in Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform

semantic-release is an automated software release tool that determines versions and generates release notes from structured commit messages.

semantic-release automates release-note generation and version updates by examining structured commit history. It requires commit messages in the format its analyzer can parse, making descriptive commits operationally important. section 5.3

Use it after packaging a module to summarize breaking changes and communicate updates to other teams. Keep the resulting release notes in a repository document such as a changelog, and retain version-control tags so artifacts remain traceable to code. section 5.3

Structured commit drives a major version

A commit such as “feat(security): store password in secrets manager” can be analyzed as a major feature, causing the automated release tool to update the tag to v2.0.0. section 5.3

How Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform covers it

How deep it goes
Examines commit history and parses message formats, but does not detail analyzer configuration or release recovery.
Examples
Uses a feat(security) commit and the resulting v2.0.0 tag as concrete examples.
What it assumes
Requires descriptive commits in the analyzer’s expected format and familiarity with repository tags and release notes.
What you can do after
Apply it via semantic-release to generate release notes and update versions from correctly formatted commits.
How it connects
Connects commit messages, release notes, changelogs, version tags, and artifact repositories.
