6.1. METviewer Official Release
Create a new vX.Y.Z official release from the develop branch.
6.1.1. Open Release Issue
Define a new issue in the METviewer repository to create the new release.
“Create the METviewer vX.Y.Z release” for an official or bugfix release.
“Create the METviewer vX.Y.Z-betaN (or -rcN) release” for a development release.
For an official or development release, assign the issue to the corresponding METviewer development project.
For a bugfix release, assign the issue to the organization level support project.
Select the target milestone.
6.1.2. 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.
git clone firstname.lastname@example.org:dtcenter/METviewer
git clone https://github.com/dtcenter/METviewer
Enter the project repository directory:
6.1.3. Checkout the Develop Branch
Checkout the develop branch:
git checkout develop
6.1.4. 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
6.1.5. Update Version Number for Release
Remove -dev from the version number:
We are naming releases with X.Y.Z format even if Z is 0.
The file containing the version number is located at docs/version.
In the METviewer/build.xml file, assign the version in the ‘dist’ target
In the METviewer/vebapp/metviewer/metviewer1.jsp file, assign the version to <div id=’release’> and <title>
Save and close the file.
In docs/conf.py, update the version, release_year, and release_date variables for the documentation.
6.1.6. 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:
Click on the project that corresponds to this release, i.e. METviewer-X.Y.Z Development
Navigate to the “Closed Issues” tab. If this tab does not exist, see GitHub Projects to manage development to create it.
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 the official release, combine the beta release sections into one section (i.e. “Version X.Y.Z release notes (YYYYMMDD)”).
Commit changes and push to GitHub.
6.1.7. Update Upgrade Instructions
Occasionally, changes will be made to software that will require users to make changes to their configuration files in order to use the latest release. For example, when ensemble post-processing was added to Gen-Ens-Prod and removed from Ensemble-Stat, users were required to make changes in their configuration files.
This section is not always applicable.
To alert the users to the necessary steps involved with the upgrade:
Update the Upgrade Instructions section of the release-notes.rst file found in the METviewer User’s Guide directory with the necessary information.
Add an “upgrade instructions” link next to the appropriate METplus component (METviewer) after “latest” and before “development” in the METplus Components Release Note Links section in the release-notes.rst file in the METplus User’s Guide in the METplus GitHub repository ONLY if there are Upgrade Instructions for this release.
6.1.9. 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.
6.1.10. Create Release Branch
Create a branch from the develop branch for the new official release and push it to GitHub.
cd METviewer git checkout develop git pull git checkout -b main_vX.Y git push -u origin main_vX.Y
6.1.11. Push Release Branch to GitHub
Push the release branch to GitHub:
release_branch=main_vX.Y git push origin $release_branch
6.1.12. Create Release on GitHub
Go to Releases on GitHub and click ‘Draft a new release’
Set the tag based on the version, starting with ‘v’, i.e. vX.Y.Z-betaN, vX.Y.Z-rcN, or vX.Y.Z
Set the branch value to ‘develop’ for a development release or ‘main_vX.Y’ for a bugfix or official release
Choose a release name (i.e. METviewer-X.Y.Z-betaN, METviewer-X.Y.Z-rcN, or METviewer-X.Y.Z)
Add a link to the release notes from the METviewer User’s Guide, i.e. https://METviewer.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 Link: Link text should be “User’s Guide” and the URL should be the top level directory of the User’s Guide hosted on the web. Beta releases can use “develop” in the URL, but for official releases, please ensure the link uses the branch name (e.g. main_vX.Y) as opposed to the tag name (e.g. vX.Y.Z). For example, use “https://metplus.readthedocs.io/en/main_vX.Y/Users_Guide/” and NOT “https://metplus.readthedocs.io/en/vX.Y.Z/Users_Guide/”
Add Link: Link text should be “Existing Builds and Docker” and the URL should be the latest Existing Builds page, i.e. https://dtcenter.org/community-code/metplus/metplus-X-Y-existing-builds (If creating a new official release, be sure to add a new Existing Builds and Docker page, if one was not already created.)

Click on “Save”.
6.1.14. Finalize Release on GitHub
Edit the milestone for the current release by updating the Due date with the actual release date.
Close the current milestone.
Create a new milestone for the first bugfix release (e.g. first vX.Y.1 (bugfix) release).
If necessary, create a new milestone for the next official release (e.g. next vX.Y.Z release).
Close the GitHub issue for creating this official release.
If necessary, reassign any remaining issues for the current milestone to other milestones.
Close the existing development project for the current milestone.
If necessary, see GitHub Projects to manage support to create a support project for the current METplus coordinated release.
If necessary, see GitHub Projects to manage development to create a development project for the next milestone.
Remove any remaining stale development branches from the new release.
Update the repository settings by resetting the Default branch to the new main_vX.Y branch:
https://github.com/dtcenter/METviewer -> Settings -> Branches (tab on left) -> change the drop down to new branch (click on stacked arrows icon next to the edit icon) -> update branch protection rules
6.1.15. Update Version on Develop Branch
Change METviewer/docs/version __version__ value to the next release after this one with -dev added to the end. Releases will loosely following these names, but are subject to change:
New Develop Version
6.1.16. Update the Documentation on the Web
Because Read the Docs is configured to automate the building of new “main” branches in the METplus components’ repositories, nothing needs to be done to build the documentation for the new release. See the Read the Docs section for further information. For an official release, it is important to update the “Default branch” to this latest “main” branch. An administrator of the METplus component repository will need to do the following to update the default branch:
Log into their Read the Docs account
Click on the appropriate METplus component project
Click on Admin in the top menu
Click on Advanced Settings in the left menu
Select the new default branch in the dropdown menu for “Default branch” (e.g. main_v4.0.0)
Ensure that “latest” points to the new default branch by clicking on “View Docs”in the upper right corner and confirm that the version number displayed in the header is the desired version for “latest”.
