What's new?	This release enables the IOT2050 PG2/SM Industrial Edge Device for Global Sales. This version features Disk Encryption, Secure Boot, and DevID pre-enabled from manufacturing. Important Note for Existing IOT2050 PG2 Devices: Existing IOT2050 PG2 Industrial Edge Devices cannot be updated to this new version via a standard firmware update. This is due to the recently enabled security features and a breaking change in the base OS. Further communication regarding update paths for these devices will be provided separately. Breaking Change from simatic-iot2050-ied-os 3.0: A breaking change is introduced in this release compared to simatic-iot2050-ied-os 3.0. The base OS has been updated to harmonize feature sets across all devices. Please be aware that initial releases may present some differences or missing features when compared to current device-specific builds (such as led management, full hardreset etc.). We highly recommend consulting the corresponding image manual for detailed information User Manual.

Known Issues	The following are the known issues: Issues Troubleshooting Connecting an Edge Device to the IEM fails and the "Nginx configuration test failed" error message is displayed during activating the Edge Device phase. Check the DNS server configuration since the error message is DNS server related. The DNS server must be configured properly and reachable for the IEM. In case several apps are being installed at the same time, it takes a while to reach the Edge Device UI. Wait for a while to reach the Edge Device UI. Depending on the restart policies of the apps, the apps might not restart automatically after the reboot (includes also firmware update since it reboots the device). These apps should be manually started. Usb stick cannot be booting via usb2 port of IOT2050 device for specific model. If the USB stick does not work properly, try with another type of USB stick. IOT2050 power is not off once device is shutdown. Only SIMATIC IOT2050 IED firmware is shutdown. - Edge apps user data is deleted after proxy conf or docker network edited Reconfigure and/or import user data after proxy changes. In case of setting the IPs in the same subnet for network interfaces, one of the connections can be broken.More than one IP in the same subnet should not be set. Different network interfaces subnet should be used. During the first login, it may take a while to reach Edge Device UI. The page can be refreshed after while. The usb stick should be unplugged after the SIMATIC IOT2050 IED installation via installer in 60 seconds. - After onboarding process via usb stick, in case of success and failure state, only Power LED is solid Green. - There is not any NTP server by default in SIMATIC IOT2050 IED. The user should add the NTP server list during or after onboarding process. NTP might not be set during onboarding process. It is recommended to set NTP server via Edge UI before onboarding process.
