As we enter Kernel Freeze for the Ubuntu Trusty Tahr 14.04 release, the Ubuntu Kernel Team felt this would be an appropriate time to officially confirm the Ubuntu 14.04 kernel will be based on the upstream v3.13 Linux kernel . For those seeking the specific details of all the changes provided in the Ubuntu 14.04 kernel, please refer to the ubuntu-trusty kernel git repository . We have also categorized the Ubuntu specific changes in our TrustyKernelDeltaReview wiki for anyone interested .
We also want to take this time to advertise what we intend to be the final kernel configurations for the main distro kernel flavors as well. The purpose is to expose the main configuration changes and provide pointers to the full configurations for those who are interested. To aid in the comparison of kernel config changes from Ubuntu 13.10 (Saucy) to Ubuntu 14.04 (Trusty), we have generated a kernel configuration comparison report . We have also posted the full Ubuntu 14.04 configurations for each arch and flavor .
