Important Notes:

1. Language Files Modifications:

• If you have modified any language files, your changes will be overwritten. The new version will come with updated language files, and your previous customizations in resources/lang will be lost.
• It's highly recommended that you back up your edited language files for future reference.

2. File Modifications:

• Any changes made to the software's core files will be lost after the update. Ensure that you have backed up any customizations or modifications.

3. Disclaimer:

• We are not responsible for any data loss that occurs during a manual update. Please ensure that you follow the backup instructions carefully.

Backup Instructions:

1. Files to Back Up:
