 # Reset to factory defaults
-The [Raspberry Pi Imager](https://www.raspberrypi.org/downloads/) provides an EEPROM recovery image which may be used to reset the bootloader and USB xHCI EEPROMs to factory defaults.
+The [Raspberry Pi Imager](https://www.raspberrypi.org/downloads/) provides GUI for creating a GUI to update the bootloader and configure the default boot-mode.

+## 2021-03-18 - Fix occasional reboot fail on Pi4B pre 1.4 - STABLE
+   * Fix GPIO expander reset issue on some Pi4B 1.1 to 1.3 boards
+
+## 2021-03-17 - Fix issue with PCIe bridges in Linux - BETA
+   * NVMe BETA boot support broke PCIe bridges in Linux. This should fix the problem
+
+## 2021-03-04 - NVMe boot support - BETA
+   * Adds support for NVMe to the bootloader with a new NVMe boot mode "6"
+     NVMe currently only works for controller 0 on namespace 1 with a page size of 4096 bytes
+     and block size of 512 bytes
+   * The default boot order has been updated to F641 for cm4 ONLY, so NVMe boot is
+     attempted after SD and USB
+
+     To use the new NVMe add "6" to the BOOT_ORDER.
+
+     This requires the latest rpi-update firmware to work or else you will see a compatibility
+     error on boot. You also need the latest kernel from rpi-update to load rootfs from NVMe
