Greg Kroah-Hartman announced a few minutes ago, February 20, that Linux kernels 3.13.4, 3.12.12, 3.10.31 LTS, and 3.4.81 LTS are now available for download.
Linux kernel 3.13.4 brings several fixes and updates for the ARM64 architecture, especially a coarse clock handling fix. It fixes a kernel bug on empty security contexts for SELinux and adds some ALSA HDA fixes for Mac Pro 1,1, Toshiba Satellite L40, and the AD1983 audio codec.
It also repairs some concurrency issues in the AES-CTR mode, as well as DES, DES3_EDE CBC, and DES3_EDE CTS for the s390 architecture, disables snapshot-aware defragmentation for the Btrfs filesystem, and many others that can be viewed in the official release announcement.
Developers or users who want to compile the latest stable kernel can download Linux kernel 3.13.4 right now from Softpedia. In addition, the stable Linux kernels 3.12.12, 3.10.31 LTS, and 3.4.81 LTS are now available for download.
