Prepare Release

This skill automates the steps required to prepare a new version release.

Instructions

1. Update Version:

   • Ask the user for the new version number (e.g. 0.4.1).
   • Update version in pyproject.toml.
   • Update __version__ variable in gwexpy/__init__.py if it exists.

2. Update Changelog:

   • Read CHANGELOG.md.
   • Create a new header for the new version with the current date.
   • Move "Unreleased" changes under this new header.

3. Build Package:

   • Clean old distribution files: rm -rf dist/ build/ *.egg-info.
   • Run build command: python -m build.
   • Check if correct .tar.gz and .whl files are created in dist/.

4. Verify:

   • (Optional) Run twine check dist/* to verify metadata validation if twine is available.
