-Here is the checklist to run before releasing a new version for mbtrack2:
-
-1. Create a new local branch from the merge develop (with all the feature branch intended to be included in the new version).
-2. Go into mbtrack2 root folder.
-3. Run the isort formatter: `isort .`
-4. Run the yapf formatter: `yapf -ir mbtrack2`
-5. Update the pyproject.toml file with version number, new dependencies and so on.
-6. Update README.md
-7. Run poetry:
-   * `poetry env use python`
-   * `poetry install`
-   * Check that the tests run without errors: `poetry run pytest`
-   * `poetry build`
-   * Test build on test pypi:
-     * `poetry config repositories.test-pypi https://test.pypi.org/legacy/`
-     * `poetry config http-basic.test-pypi __token__ api_token`
-     * `poetry publish -r test-pypi`
-     * Install in a clean virtual environment (e.g. google colab) to check that it is ok using:
-     * `pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple mbtrack2`
-8. Merge to stable with a new tag and changelog.
-9. Publish on pypi:
-   * `poetry config http-basic.pypi __token__ api_token`
