Semantic-release is an automated release management tool that determines version increments, generates changelogs, and publishes software packages by analyzing commit history against standardized conventions. It functions as a plugin-based orchestrator that integrates directly into continuous integration pipelines to manage the entire release lifecycle, from verifying environment conditions to distributing artifacts.
The project distinguishes itself through its commit-message-driven approach, which enforces consistent versioning standards and automates the creation of release notes based on the scope of changes. It supports complex release strategies, including multi-branch mapping for parallel release streams, maintenance patches for legacy versions, and the publication of pre-release versions to specific distribution channels.
Beyond core versioning, the system provides a highly extensible lifecycle that allows for custom automation through hooks and third-party plugins. It includes robust support for supply chain security, enabling the generation of verifiable provenance attestations and secure credential management via environment-aware secret injection and identity provider authentication.
The tool is designed for integration into automated build environments, though it also supports local execution for manual overrides and process simulation. Configuration is handled through external files, allowing teams to standardize release workflows and share settings across multiple projects.
