------------------------------------------------------------
[1] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

------------------------------------------------------------
[2] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

------------------------------------------------------------
[3] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.
The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.
The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

III. Additional Feedback on FRITZ!OS
====================================

In addition to direct feedback in our lab area en.avm.de/fritz-lab, there are three additional feedback functions in the user interface which provide information. FRITZ! has automated the processing of feedback supplied by these functions.

1) Mobile communications feedback: "Internet/5G Information/Feedback"
2) WiFi feedback: "Wireless / Radio Network", Feedback icon after the clients
3) VoIP feedback: "Telephony / Telephone Numbers / Voice Transmission", "Other" column: Feedback icon after each call


IV. Information on the Lab Update
=================================

This FRITZ! Lab firmware is a beta version. FRITZ! tested the software in standard environments before making it available to the public, but it may still result in malfunctions. FRITZ! will not be liable for any damages that arise from the use of the lab version.

Information on Working with Lab Versions

We appreciate any feedback from our users, which can be submitted on the page en.avm.de/fritz-lab.
This page also presents all of the current FRITZ! Lab versions with corresponding feedback areas.

Before You Start Testing the Lab Version

1) You have not installed the latest firmware for your FRITZ!Box yet? Then you must first update the firmware to the latest release.
2) Save your current settings under "System / Backup". The saved settings will be needed if you want to switch back from the lab firmware back to the release firmware.


Testing the Lab Version

Once the latest firmware has been installed on your FRITZ!Box and you have saved your current settings, you can begin testing.

1) Unzip the "fritzbox-6860_5g-labor-xxxxx.zip file".
2) Use the FRITZ!Box user interface to install the update:
- Select "View: Advanced" in the footer.
- Navigate left in the menu to "System / Update".
- Switch to the "FRITZ!OS File" tab.
- Follow the instructions displayed on the screen.
Enter in the input field the path to the lab firmware and the name of the firmware itself (FRITZ.Box_6860_5G-08.10-xxxxx-LabBETA.image).
3) The firmware is transferred to the FRITZ!Box. Then the FRITZ!Box will restart.


Restoring Your Device to the Condition It Was in Before Testing

You can restore the official FRITZ!OS to your FRITZ!Box at any time using the included Windows program "FRITZ.Box_6860_5G-08.03-recover" (included in the lab package).


Important note:
 The alternative option to restore the official FRITZ!OS for your FRITZ!Box via "System / Update / FRITZ!OS" is unfortunately not
 available with this lab version. This option will only be available again with one of the upcoming lab versions.
