* **Serial Names**: Serial interfaces now have predicable aliases in /dev/serial/by-label/ based on the device-tree node name. The behavior of /dev/ttyS devices has not been changed.

**Linux Kernel**
^^^^^^^^^^^^^^^^

* **Kernel Update**: Update to v6.12.57 (tag: v6.12.57-11.02.11-phy6)
* **TI SDK Update**: Bump from TI Processor SDK v11.01.05 to v11.02.11

* **RAUC Bootmeth**: Merged upstream RAUC A/B bootmeth with memory handling fixes

**Issues Fixed**
^^^^^^^^^^^^^^^^


**Known Issues**
^^^^^^^^^^^^^^^^

* **Securiphy**: There was a regression in the chain of trust while booting. When switching to u-boot standard boot we added an unsigned boot script, which is a violation of the chain of trust. This only applies to the securiphy distro.
* **Linux RT Latency**: Real-time Linux can have worst-case latencies up to 600 microseconds under heavy memory load.
* **Flashcp Command Failures**: Occasional failures during verification in `flashcp`.
* **Weston Startup Issues**: Failure to start Weston when both HDMI and LVDS are active at boot.
* **Low-Power Mode MCU Issue**: MCU-only low-power mode is non-functional when M4F firmware is loaded.
* **USB I/O errors**: There may be I/O errors with **/dev/sdb** during the boot process from eMMC. However, no issues have been observed when reading from or writing to the drive after booting.
