Linus Torvalds宣布3.12穩定版內核，帶來很多驅動更新和改進，比如Radeon顯卡，AMD APU，高通枭龍/Adreno，NVIDIA Optimus，各種文件系統和其他驅動等更新。
Linus在郵件列表中說：“我本來在猶豫要不要來個RC8，不過下周要出去旅游，網絡不好，還是不延遲了”。並表示3.19後就會進入4.0時代，不過那是一年後的事情了。
該版新特性：
The Radeon open-source kernel graphics driver has improved Dynamic Power Management, but it won’t be until Linux 3.13 where Radeon DPM is enabled by default along with HDMI audio.
A brand new DRM/KMS driver in the form of the Snapdragon MSM driver written by Rob Clark to go along with his reverse-engineered Freedreno driver for Qualcomm Snapdragon/Adreno graphics.
Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
Experimental DRM render nodes support done by David Herrmann over the summer.
AMD Berlin APU support as the first APU built upon AMD’s Heterogeneous System Architecture (HSA).
The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
zRAM has been promoted out of the staging area of the kernel. ZRAM supports a compressed block device in RAM to avoid paging to disk and is mostly of benefit for systems with limited amounts of system memory.
Various staging driver updates and sound driver work and other glorious work.
