release notes based on GitHub commits. It analyzes commit messages between two points (tags, commits, or dates) and formats them into structured release notes.\n\n## Features\n\n- Fetch commits from GitHub repositories\n- Parse commit messages to categorize changes\n- Generate formatted release notes in Markdown\n- Support for conventional commit format\n- Customizable output format\n\n## Usage\n\n1. Visit the app URL\n2. Enter your repository details (owner/repo)\n3. Specify the range for commits (tags, commit hashes, or dates)\n4. Generate your release notes\n5. Copy or download the formatted output\n\n## Setup\n\nThis app requires a GitHub Personal Access Token with `repo` scope to access repository data. Set this as an environment variable in Val Town:\n\n```\nGITHUB_TOKEN=your_personal_access_token\n```\n\n## Project Structure\n\n- `backend/` - API endpoints and GitHub integration\n- `frontend/` - User interface for the app\n- `shared/` - Shared types and utilities\n\n## Technologies\n\n- TypeScript\n- GitHub REST API\n- Hono (backend framework)\n- React (frontend)\n- TailwindCSS
