Version 2.5.25-dj1 of Linux
Release Notes: This version features improvements to the i386 machine check handler, consistent usage of static in keyboard maps, improved list handling in dcache.c, PCI DMA updates for the Roadrunner HIPPI driver, and the conversion of various i2c drivers to the new interface. There were fixes for the negative memcpy issue in the Orinoco driver, compilation issues in agpgart, airo, aztcd, and sonycd, module creation off-by-ones, garbage in /proc/partitions, and typo fixes in the ipsysctl docs. Cleanups were made to region handling, RPC receiving, pci_enable_device(), and init_etherdev in various network drivers.
Other releases
Release Notes: Linux is now able to use SSDs as harddisk caches. Btrfs has native RAID 5 and 6 support. Changes to the network subsystem improve the way server jobs are distributed across multiple processor cores. Linux now has the ability to "suspend freeze". KVM hypervisor now supports ARM cores. Changes to the network subsystem will enable the kernel to be more efficient when distributing network traffic across multiple processor cores. Included are drivers for new AMD graphics chips and soon-expected Wi-Fi components from Intel.
Release Notes: This release includes support in Ext4 for embedding very small files in the inode, which greatly improves the performance for these files and saves some disk space. There is also a new Btrfs feature which allows quickly replacing a disk, a new filesystem, F2FS, optimized for SSDs, support for filesystem mounts, UTS, IPC, PIDs, and network stack namespaces for unprivileged users, accounting of kernel memory in the memory resource controller, journal checksums in XFS, an improved NUMA policy redesign, and removal of support for 386 processors.
Release Notes: This release adds support for the new ARM 64-bit architecture, ARM multiplatform, which gives the ability to boot into different ARM systems using a single kernel, support for cryptographically signed kernel modules, Btrfs support for disabling copy-on-write on a per-file basis using chattr, faster Btrfs fsync(), a new experimental 'perf trace' tool modelled after strace, support for the TCP Fast Open feature on the server side, experimental SMBv2 protocol support, stable NFS 4.1 and parallel NFS, and a vxlan tunnelling protocol that allows transfer of Layer 2 Ethernet packets over UDP.
Release Notes: This release includes several Btrfs updates. There is a new X32 ABI that allows it to run programs in 64-bit mode with 32-bit pointers. Several updates to the GPU drivers. Early mode setting of Nvidia Geforce 600 'Kepler'. Support for AMD RadeonHD 7xxx and AMD Trinity APU series. Support for Intel Medfield graphics. Support for x86 CPU driver autoprobing. A device-mapper target that stores cryptographic hashes of blocks to check for intrusions. Another target to use external read-only devices as origin sources of thin provisioned LVM volumes. Several perf improvements.
Release Notes: Android code has been merged in. This release updates btrfs, adds support for Open vSwitch, and has network stack optimization, better ext4 online resizing, TI C6X architecture support, and EFI boot support.
