- Proper CHANGELOG.md for release management
- Statistics optimizations implemented across all storage adapters
- In-memory caching of statistics data
- Batched updates with adaptive flush timing
- Time-based partitioning for statistics files
- Error handling and retry mechanisms for statistics operations

### Changed

## 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.
