and this project adheres to [Semantic Versioning](http://semver.org/).

## [9.0.3] - 2026-06-28

### Fixed

- Made restore() method public

---

## [9.0.2] - 2026-06-28

### Fixed

- Fixed types, replaced fs streams usage with Readable and Writable

---

## [9.0.1] - 2026-06-28

### Fixed

- Updated documentation

---

## [9.0.0] - 2026-06-28 (Breaking changes)

### Removed

- **File system integration**: We've streamlined the core library by removing direct file system handling. This gives you complete control over storage and restoration logic, allowing you to implement custom solutions tailored to your needs.
- **Writer/reader mode bifurcation**: Simplified the codebase by consolidating mode-specific behavior, making the library more intuitive to work with.

### Changed

- The following options are now deprecated and removed in current and future releases:
  - `options.pathToDumpFile`
  - `options.storingInterval`
  - `options.writer`

- **Updated method signatures**:
  - `init()` and `restore()` now require a `stream: ReadStream` argument
  - `store()` now requires a `stream: WriteStream` argument

**Migration guide**: If you were relying on automatic file-based storage, you'll need to manage stream handling in your application. This provides greater flexibility and control over persistence.
