            It's time to bump the major version from ${majorVersion} to v${currentYear}.

            ### Steps

            1. **Create the new major version tag:**
               \`\`\`bash
               git tag -a v${currentYear} -m "Major version v${currentYear}"
               git push origin v${currentYear}
               \`\`\`

            2. **Bump all action references:**
               \`\`\`bash
               make bump-major-version OLD=${majorVersion} NEW=v${currentYear}
               \`\`\`

            3. **Update documentation:**
               \`\`\`bash
               make docs
               \`\`\`

            4. **Commit and push:**
               \`\`\`bash
               git push origin main
               \`\`\`

            ### Verification

            \`\`\`bash
            make check-version-refs
            \`\`\`
            `,
