21.05.2 New Features and Changes

This is a maintenance release of pfSense® Plus software. pfSense Plus software version 21.05.2 corrects an issue with the pre-installed Netgate Firmware Upgrade package on Netgate 6100 hardware devices.

In certain circumstances the pre-installed Netgate Firmware Upgrade package could have incorrectly offered to downgrade the firmware when the hardware shipped from the factory with a newer firmware version than the copy contained within the 21.05.1 installation image.

The pfSense Plus software version number was increased for all models of Netgate hardware for consistency, but there are no functional changes for other hardware platforms. Upgrading a device in the field to 21.05.2 is not necessary at this time, but users may do so if they wish.
