Release Process

Creating a new release for OSQP 0.6.x

• Releases for OSQP 0.6.x should be made from the v0.6.x branch. The general process is:

  • git checkout v0.6.x

  • Branch out of the v0.6.x branch, make any desired changes.

  • Push to Github. Ensure that CI (triggered on all pushes/PRs) passes on all platforms. Ubuntu/Windows/Macos-Silicon/Macos-Intel are handled in .github/workflows/build.yml, aarch64 is handled in .github/workflows/build_aarch64.yml).

  • Once CI passes, decide on a new version, say 0.6.42. Make changes to the following 3 places to match the selected version:

    • src/osqp/codegen/files_to_generate/setup.py, Line 77
    • src/osqp/interface.py, Line 2
    • src/osqppurepy/_osqp.py, Line 333

    These files/line numbers are also obtainable using something like grep -r 0.6.41 (if 0.6.41 is the current version, for example). It's possible to use bumpversion or a similar library to handle all these cases automatically, but it's absolutely not worth introducing a new dependency at this point, since v0.6.x releases are anticipated to be rare.

  • Send a PR towards the v0.6.x branch. Merge if CI passes.

  • Tag the merge commit on the v0.6.x branch with the version tag (git tag v0.6.42 if 0.6.42 is the current version, for example). Notice the v prepended to the version number in the tag. The presence of the tag is what triggers the CI to initiate a new release on PyPI.
