## How to Update This Changelog
This project now uses [standard-version](https://github.com/conventional-changelog/standard-version) to automatically generate the changelog from commit messages.
### Commit Message Format
Follow the [Conventional Commits](https://www.conventionalcommits.org/) specification for your commit messages:
```
<type>(<scope>): <description>
[optional body]
[optional footer(s)]
```
Where `<type>` is one of:
- `feat`: A new feature (maps to **Added** section)
- `fix`: A bug fix (maps to **Fixed** section)
- `chore`: Regular maintenance tasks (maps to **Changed** section)
- `docs`: Documentation changes (maps to **Documentation** section)
- `refactor`: Code changes that neither fix bugs nor add features (maps to **Changed** section)
- `perf`: Performance improvements (maps to **Changed** section)
### Examples:
```
feat(storage): add new file system adapter
fix(hnsw): resolve index corruption on large datasets
docs(readme): update installation instructions
refactor(core): simplify graph traversal algorithm
```
### Releasing a New Version
To release a new version:
1. Ensure all changes are committed
2. Run one of:
- `npm run release` (for patch version)
- `npm run release:patch` (same as above)
- `npm run release:minor` (for minor version)
- `npm run release:major` (for major version)
3. Push changes with tags: `git push --follow-tags origin main`
The changelog will be automatically updated based on your commit messages.
