Fix changelog grab failure when only one header exists. by jshigetomi · Pull Request #27371 · PowerShell/PowerShell

PR Summary

This pull request improves the robustness of the changelog extraction logic in the .pipelines/templates/release-githubNuget.yml pipeline script. The script now handles cases where there may be only one release heading in the changelog and provides a clear error if no headings are found.

Changelog extraction improvements:

• Ensured that $headingStartLines is always an array and added a check to throw an error if no release heading matching the expected pattern is found in the changelog file.
• Updated the logic to correctly handle changelogs with only one release heading by extracting content through the end of the file, and fixed the calculation of the number of lines to extract.

PR Context

This unblocks 7.7.0-preview.1 github release
