# Releasing a new OSRM version
|
|
|
|
We are using http://semver.org/ for versioning with major, minor and patch versions.
|
|
|
|
## Guarantees
|
|
|
|
We are giving the following guarantees between versions:
|
|
|
|
### Major version change
|
|
|
|
- There are no guarantees about compatiblity of APIs or datasets
|
|
- Breaking changes will be noted as `BREAKING` in the changelog
|
|
|
|
### Minor version change
|
|
|
|
We may introduce forward-compatible changes: query parameters and response properties may be added in responses, but existing properties may not be changed or removed. One exception to this is the addition of new turn types, which we see as forward-compatible changes.
|
|
|
|
- Forward-compatible HTTP API
|
|
- Forward-compatible C++ library API
|
|
- Forward-compatible node-osrm API
|
|
- No compatiblity between OSRM datasets (needs new processing)
|
|
|
|
### Patch version change
|
|
|
|
- No change of query parameters or response formats
|
|
- Compatible HTTP API
|
|
- Compatible C++ library API
|
|
- Compatible node-osrm API
|
|
- Compatible OSRM datasets
|
|
|
|
## Release and branch management
|
|
|
|
- The `master` branch is for the bleeding edge development
|
|
- We create and maintain release branches `x.y` to control the release flow
|
|
- We create the release branch once we tagged the final version `x.y.0` version, RCs go on master
|
|
- No minor or major version will be released without a code-equal release candidates
|
|
- For quality assurance, release candidates will be run on the demo server for 24 hours before releaseing the version proper
|
|
- Patch versions may be released without a release candidate
|
|
- We may backport fixes to older versions and release them as patch versions
|
|
|
|
## Releasing a version
|
|
|
|
1. Check out the appropriate release branch `x.y`
|
|
2. Make sure all tests are passing (e.g. Travis CI gives you a :thumbs_up:)
|
|
3. Make sure `CHANGELOG.md` is up to date.
|
|
4. Make sure the OSRM version in `CMakeLists.txt` is up to date
|
|
5. Use an annotated tag to mark the release: `git tag vx.y.z -a` Body of the tag description should be the changelog entries.
|
|
6. Use `npm run build-api-docs` to generate the API documentation. Copy `build/docs/*` to `https://github.com/Project-OSRM/project-osrm.github.com` in the `docs/vN.N.N/api` directory
|
|
6. Push tags and commits: `git push; git push --tags`
|
|
8. Proceede with the `node-osrm` release as [outlined in the repository](https://github.com/Project-OSRM/node-osrm/blob/master/docs/releasing.md).
|
|
9. If not a release-candidate: Write a mailing-list post to osrm-talk@openstreetmap.org to announce the release
