## [0.2.6] - 2024-06-22
### Fixed
- Fix issue #19: Update Dockerfile to ensure compatibility across multiple platforms.

## [0.2.5] - 2024-06-18
### Added
- Added five important hooks to the crawler:
  - on_driver_created: Called when the driver is ready for initializations.
  - before_get_url: Called right before Selenium fetches the URL.
