Linux 2.6.30 is currently in development. The release candidate -rc1 was released the 7 April 2009, closing the merge window.
This page is, obviously, a work in progress.
Summary:
1. Prominent features (the cool stuff)
1.1. NILFS2 log-structured filesystem
[http://www.nilfs.org NILFS2] (new implementation of a log-structured file system 2) is a log-structured filesystem, which allows continuous snapshotting.
1.2. Support for Object-Based Storage Device
Object-Based Storage Device (OSD) are basically "smart" disks, which do not store the data as blocks, but more elaborated objects. 2.6.30 adds support to these devices in the SCSI layer, as well as the addition of a filesystem (exofs, Extended Object File System) able to use them.
([http://lwn.net/Articles/305740/ LWN's Article], where exofs is still known by its old name, osdfs)
1.3. Local Filesystem Cache
FS-Cache is an infrastructure to locally cache remote (or slow) filesystems. It is described in more details in [http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/filesystems/caching/fscache.txt].
