Milestone Creator

A GitHub Action that automatically creates milestones when a release is created from a semantic version tag.

Features

• Closes the milestone matching the release tag version (creates it if it doesn't exist)
• Creates upcoming milestones with incremented versions
• Supports v prefix (e.g., v1.2.3) or plain versions (e.g., 1.2.3)
• Skips upcoming milestone creation if they already exist

  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    upcoming-milestones: '3'

Use patch version increment

When release v1.0.0 is created, this closes milestone v1.0.0 and creates milestone v1.0.1

- uses: octoberswimmer/milestone-creator@v1
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    version-increment: 'patch'

Use major version increment

When release v1.0.0 is created, this closes milestone v1.0.0 and creates milestone v2.0.0

- uses: octoberswimmer/milestone-creator@v1
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    version-increment: 'major'
