Version 4.503 Beta  
This update introduces new and optimized operating system, modified file structure and the following brand new features: Update package downloaded in the background, without locking the interface. Creating encrypted local backup that can be downloaded to your hard drive and later restored. Creating encrypted backups, stored in Fibaro cloud that can be later restored. Customized icons included to backup. Restoring backup with full rollback (restores also software version) or with current software version (up from 4.503). Backups created so far become incompatible.
Changes related to GDPR: Displaying the number of remaining attempts to log in. Blocking the possiblity to log in for 30 minutes after 5 unsuccessful attempts from a given IP address. Displaying the value of time remaining to unlock the ability to log in. E-mail notification sent to admin after 5 unsuccessful attempts to log in. E-mail message sent every 90 days that recommends changing your password.
Other improvements: New, more reliable file structure. No need to use the recovery pendrive. Optimized software update process minimizing the risk of potential errors during system update. Easier and more intuitive setting of advanced parameters. Information about scenes used by a given device available in its configuration. Notification after successful update recommending to create a backup if there is no compatible backup. Possibility to disable creating auto-backup in Fibaro cloud before performing update. Indication after exceeding 90% of cloud backup storage. Compatibility with cameras connecting through https protocol. Added support for FIBARO Wall Plug UK - type G. Adding a time zone for Kuwait.
Resolved issues: Losing the synchronization of the set time. No variables list while creating a virtual device. No icon change lock via the remote access. Switching a number of grouped devices results in 503 error. Non-admin users cannot modify their own e-mail address and password. Number of devices counted in a particular backup contains all endpoints, active plugins and users instead of devices only. Notification suggesting replacing the battery of FIBARO The Heat Controller instead of charging. Scene based on time condition results in 'timer handler failed with error' message. No possibility to set time manually. No power consumption bars in 'Top 5' section. Other minor fixes.     Mise à jour HC-Lite : utiliser l'astuce présentée par @le citron vert :
