6.2. METplotpy Bugfix Release

Create a new vX.Y.Z bugfix release from the main_vX.Y branch.

6.2.1. Clone the Project Repository

• Create and work in a new directory to ensure a fresh environment:

mkdir release-X.Y.Z
cd release-X.Y.Z

• Run the clone command to obtain the repository.

Using SSH:

git clone git@github.com:dtcenter/METplotpy

Using HTTP:

git clone https://github.com/dtcenter/METplotpy

• Enter the project repository directory:

cd METplotpy

6.2.2. Checkout the Main Branch

Checkout the main branch for the X.Y release. If you are creating the METplotpy-X.Y.Z official or bugfix release, checkout main_vX.Y.

git checkout main_vX.Y

6.2.3. Create Release Feature Branch

• Create a feature branch in which to update the version number and add release notes being sure to include the GitHub issue number for the new release.

git checkout -b feature_NNNN_vX.Y.Z       # for an official or bugfix release
git checkout -b feature_NNNN_vX.Y.Z-betaN # for a development release
git checkout -b feature_NNNN_vX.Y.Z-rcN   # for a development release

6.2.4. Update Version Number

• Update the version:

  • In ‘docs/conf.py’, update the ‘version’, ‘release_year’, and ‘release_date’ variables for the documentation.

6.2.5. Update Release Notes

You can refer to the GitHub Project board to see what has changed for this release. Open the following URL in a browser:

https://github.com/orgs/dtcenter/projects

• Click on the project that corresponds to support for the release, i.e. METplus Version X.Y Support

• Navigate to the “Closed Issues” tab. If this tab does not exist, see GitHub Projects to Manage Support to create it.

• Find the closed issues with dtcenter/METplotpy in the Repository column that have been added since the last bugfix release for METplotpy.

• Open the following URL in a browser:

https://github.com/dtcenter/METplotpy/issues

• Navigate to the METplotpy X.Y.Z Milestone to check for any issues that may not appear in the METplus Version X.Y Support project board.

• Update the release-notes.rst file found in the User’s Guide directory.

• Consider organizing release notes into logical groups (e.g. Enhancements, Bugfixes, Documentation, etc.) and modifying GitHub issue titles for consistency. The release notes should match the GitHub issue titles, when possible.

• Use your best judgement to apply bold formatting for any major or important changes.

• When creating a bugfix release, leave the “Version X.Y.0 release notes (YYYYMMDD)” in place, along with any other bugfix release notes and add a section above for the latest bugfix release (i.e. “Version X.Y.Z release notes (YYYYMMDD)”).

• Commit changes and push to GitHub.

6.2.6. Merge Release Issue

• After updating the release-specific content on a release feature branch, submit a pull request to merge those changes back into the source branch.

6.2.7. Create Release on GitHub

• Ensure that any and all dependent releases for METplotpy have been created according to Release Dependencies.

• Go to Releases on GitHub and click ‘Draft a new release’

• For ‘Choose a tag’, create a new tag based on the version, starting with ‘v’ (i.e. vX.Y.Z-betaN, vX.Y.Z-rcN, or vX.Y.Z)

• Define the ‘Target’ branch as:

  • ‘develop’ for a beta development release

  • ‘main_vX.Y’ for a release candidate, bugfix, or official release

• Define the ‘Release title’ based on the repository name and version, without a leading ‘v’ (i.e. METplotpy-X.Y.Z-betaN, METplotpy-X.Y.Z-rcN, or METplotpy-X.Y.Z)

• Add a link to the release notes from the METplotpy User’s Guide, i.e. https://METplotpy.readthedocs.io/en/vX.Y.Z-betaN/Users_Guide/release-notes.html (Note: the URL will not be active until the release is created) Refer to a previous release to easily copy and modify this information.

• Add links to the HTML and PDF versions of the METplotpy User’s Guide on ReadTheDocs. https://METplotpy.readthedocs.io/_/downloads/en/vX.Y.Z-betaN/pdf/ (Note: the URL will not be active until the release is created) Refer to a previous release to easily copy and modify this information.

• If this is a development release, check the box that says “This is a pre-release”.

• Click on “Publish release”.
