# Raspberry Pi 4B, 400 and CM4 bootloader EEPROM releases
|
|
This page provides links to the production and development release images for the bootloader EEPROM on BCM2711-based Raspberry Pi computers. Normally, the
|
|
bootloader is automatically updated after an APT update via the [rpi-eeprom-update](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#automatic-updates) utility.
|
|
|
|
## Release notes
|
|
Release notes are available [here](https://github.com/raspberrypi/rpi-eeprom/blob/master/firmware/release-notes.md).

|
## USB MSD boot
|
|
Please see the [USB mass storage boot](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#usb-mass-storage-boot) guide.
|

|
## Old EEPROM images
|
|
Old bootloader images are periodically removed from the APT package to reduce the disk space, but are still available via Github [here](https://github.com/raspberrypi/rpi-eeprom/tree/master/firmware/old).
|
|
|
|
**Old releases may fail to boot on newer hardware revisions.**
