Your PrestaShop store consists of numerous modules linked to the core software. These modules must be updated regularly to benefit from the following advantages:
- corrections of security vulnerabilities
- bug fixes
- improvements of the features
- new features
Keeping the modules up to date thus allows you to have a more stable, more secure store with the least possible operational issues. For more advice on updates in general, you can consult the best practices of the platform Cybermalveillance.gouv.fr.
