Version history below is shared across all supported coreboot boards in this repository, starting from when release notes became unified across boards.
General Updates: * Improved sleep/wake and reset reliability * Added support for EFI capsules for easier, more secure updates * Updated BIOS setup layout, with a simpler user interface and clearer security shortcuts New Options: * [StarFighter] Memory Speed Security Updates: * Add an option to lock the BIOS Setup with a password * BIOS Lock is now enabled by default * Added TCG OPAL Storage disk encryption support, including S3 unlock support * Improved Secure Boot key enrollment behavior when a KEK is already present Bug Fixes / Enhancements: * Fixed power LED “breathing” behavior in S3 * Fixed Wake-on-LAN on Byte (including Wake-on-LAN in S5 where supported) * [StarFighter] Enabled the card reader
General Updates: * Improved sleep/wake and reset reliability * Added support for EFI capsules for easier, more secure updates * Updated BIOS setup lauouy, with simpler user-interface New Options: * [StarFighter] Memory Speed Security Updates: * Add an option to lock the BIOS Setup with a password * BIOS Lock is now enabled by default Bug Fixes / Enhancements: * Fixed power LED “breathing” behavior in sleep (S3). * Fixed Wake-on-LAN on Byte * Updated platform defaults based on fan presence
General Updates * EC startup time has been reduced from 415ms to 170ms * Hardened power sequence to avoid getting stuck * Updated Intel microcode * eSPI Virtual Wires are now interrupt-driven for better response times * Updated default settings aimed at performance * Remove the power button debounce (double press is no longer required) * Updated firmware menu that now shows battery level and allows adjusting the time and date * The system will now wake if suspended, and the battery gets too low New Options: * Enable/Disable/Dim the power LED * Enable/Disable/Dim the charging LED * Enable/Disable Total Memory Encryption * Enable/Disable BIOS Lock Security Updates: * Updated UEFI revocation list * Added support for LUKS and BitLocker Bug Fixes / Enhancements * Fixed reset paths in coreboot to avoid the system hanging when changing settings that required global resets * Guard against SMBUS transactions not completing * Increase SMM store size in coreboot to allow UEFI revocation list updates to be installed from the LVFS * Fixed backlight level restoration after suspend (S3) * Fixed resuming from hibernation (S4) * Fixed an issue that prevented powering off in certain conditions * Fixed sound output on Windows * Fixed an issue where the fan could stall * Fixed disabling the card reader * Fixed Device Manager constantly refreshing on Windows * Fixed the capabilities reported by the TPM driver
General Updates: * Added capsule update support, with graphical update progress, more reliable flashing, and better preservation of existing settings and unchanged firmware data * Reworked the firmware setup menu into a cleaner Settings-style layout, with clearer Boot and Security sections New Options: * Configurable boot timeout * Digital Signal Processor * [StarFighter] Touchpad Vibration Intensity * [StarFighter] Touchpad Click Force * [StarFighter] Touchpad Release Force * [StarFighter] Touchpad Tracking Speed * [StarFighter] Speaker Idle Security Updates: * Added BIOS password protection * Added TCG OPAL storage support for compatible NVMe drives, including S3 unlock support Bug Fixes / Enhancements: * Added better HiDPI scaling in firmware setup and improved graphics handoff, helping hibernation (S4) behave more reliably * Corrected panel timing values against panel datasheets across current Star Labs platforms * Increased PWM frequencies across supported boards to reduce flicker * Added staged NVMe power sequencing on supported platforms so third-party and slower-to-initialize drives initialise more reliably * [StarFighter] Enabled the card reader in firmware * [StarLite Mk V / Horizon] Increased speaker output configuration to the intended 2.5W path * Improved keyboard scan debounce handling so new key presses are detected more consistently * Improved S3 power LED breathing behaviour for smoother and more consistent transitions * Simplified reduced-brightness handling for the LEDs * [Byte Mk III] Fix fan curve setting
General Updates: * Added support for AMD Cezanne models (Byte Mk I and StarBook Mk VI) * Added coreboot support for Byte Mk I and StarBook Mk VI-AMD New Options: * Custom power profile controls for PL1, PL2, PL4, and CPU thermal throttle temperature * Per-port PCIe power management controls * HDA DSP firmware setup toggle Bug Fixes / Enhancements: * Reduced false CPU throttling from charge-controller PROCHOT while preserving brown-out protection * [StarFighter] Reduced touchpad startup delay and fixed touchpad settings not being applied * [StarFighter] Improved Wi-Fi, Bluetooth, and touchpad setup handling * [StarLite Mk V] Improved battery free operation
General Updates: * Added support for AMD Cezanne models (Byte Mk I and StarBook Mk VI) Bug Fixes / Enhancements: * Improved capsule update reliability * Fixed hibernation failures caused by inconsistent payload memory maps * Ignored malformed OS-created UEFI variable records instead of blocking boot * Avoided EDK2 serial port reinitialisation * Dropped shell networking when networking support is disabled * Disable TPM1 * Fixed PCR0 Reconstruction * Improved HiDPI logo, console text, and graphics handoff handling * Reduced false CPU throttling from charge-controller PROCHOT while preserving brown-out protection * Improved low battery handling with a warning splash, adjusted wake threshold, and graceful critical battery shutdown * Dynamically set PL4 from charger and battery state * Fixed memory speed changes reusing stale training data * Fixed ANX7447 dead battery charging * Added Fn+F hot key for 100 0.000000an duty * Stored the serial number in firmware variables * [StarFighter] Reduced touchpad startup delay and fixed touchpad settings not being applied * [StarLite Mk V] Improved battery free operation and fixed auto-rotation on Ubuntu * [StarBook MkVIr2-Intel] Fixed blue sleep LED breathing * Improved keyboard scan debounce to reduce ghosting and missed keys
