npm Breaking Changes & Migration

npm breaking changes between two versions of a package, before a package upgrade: the documented breaking changes per version, read from the real CHANGELOG, GitHub release notes and alpha/beta/rc notes, plus major version bumps, Node.js engine, ESM/CJS, exports and peer dependency changes, migration guide links and a verdict. Exact versions or a major ('4'); a source URL for every item. One call per dependency upgrade.

npm changelog between two versions: the full release notes of every version in the range (newest first, up to 100), from the package CHANGELOG and GitHub releases, with publish dates, bump type (major, minor, patch), npm deprecations, extracted breaking changes and package.json manifest changes. Covers a whole package upgrade or dependency upgrade in one call instead of reading dozens of release pages.

PyPI breaking changes between two versions of a Python package, before a pip package upgrade: the documented breaking changes per version from the project's CHANGELOG, HISTORY or CHANGES file and GitHub release notes (alpha/beta/rc folded into the major), plus Requires-Python and required dependency changes, yanked versions, migration guide links and a verdict. PEP 440 versions ('1.10.13', '2.0') or a major ('1'); a source URL for every item.

GitHub Actions upgrade brief between two versions of an action (e.g. actions/checkout v3 to v4): breaking changes from release notes and migration docs, action.yml input/output diff (removed, renamed, new required inputs, changed defaults), Node runtime change (node16/node20 removed, node24), deprecations, concrete workflow edits with SHA pin, and sources.

PyPI changelog between two versions of a Python package: the full release notes of every version in the range (newest first, up to 100) from the project's changelog file and GitHub releases, with publish dates, bump type, yanked flags, extracted breaking changes and Requires-Python / dependency changes. One call instead of reading a long HISTORY or CHANGES file before a Python package upgrade.

GitHub Actions upgrade brief: what changes when a workflow moves an action from one version to another (actions/checkout v3 to v4, setup-node, upload-artifact, any owner/repo[/path]). Breaking changes from release notes, CHANGELOG and migration docs, action.yml diff (removed, renamed or new required inputs, changed defaults, removed outputs), Node runtime change (node16/node20 removed, node24), deprecations, concrete workflow edits with the SHA pin, and sources.

Dependency upgrade plan for up to 5 npm or PyPI packages: per package the breaking changes to the target version, major bumps, engine/Python and peer dependency changes, migration guides and a risk score, ordered by risk, plus peer requirements between the listed packages.

PyPI breaking changes between two versions of a Python package, from its CHANGELOG/HISTORY/CHANGES file and GitHub releases: breaking items per version, Requires-Python and dependency changes, yanked versions, migration guide links and a verdict.

PyPI changelog between two versions of a Python package: full release notes per version (newest first) with dates, bump type, yanked flags, extracted breaking changes and Requires-Python / dependency changes.

Dependency upgrade plan for up to 5 npm or PyPI packages in one call (e.g. react, react-dom and next together): for each package the breaking changes between your version and the target, major bumps, Node.js or Python and peer dependency changes, migration guide links and a risk score, ordered by upgrade risk, plus the peer dependency requirements between the listed packages (next 15 needs react 19). Built from real changelogs and GitHub releases.
