Linaro 13.08 Release With Linux Kernel 3.11 and Android 4.3

Linaro 13.08 has been released with Linux Kernel 3.11-rc6 (stating), Kernel 3.10.9 (LSK – beta), and Android 4.3.

This month is the first release based on Android 4.3, which was only pushed to AOSP at the end of last month. I can also see work on new SoCs/hardware this month with Texas Instruments Keystone II ARM Cortex A15+DSP SoC and Fujitsu AA9 board (Which processor?, I could not find out). A lot of work also appears to have gone in OpenEmbedded, further optimizations have gone into NEON optimized AES encryption in OpenSSL, and more. It’s also the first time I can see a Ubuntu Raring engineering build image for HighBank (Calxeda Energycore).

Here are the highlights of this release:
