 - Bug fixes and small improvements
============================================================================
What is new in 2.8
 - More scalable directory tree locking
 - Atomic open(O_TRUNC) support
 - Support big write requests on kernels 2.6.26 and newer
 - Out-of-tree fuse module removed
 - Better NFS exporting support
 - New ioctl and poll requests
 - New CUSE (Character Device in Userspace) interface
 - Allow umask processing in userspace
 - Added cache invalidation notifications
 - Bugfixes and small improvements
============================================================================
What is new in 2.7
 - Stacking support for the high level API
 - Add filename charset conversion module
 - Improved mounting
============================================================================
What is new in 2.6
 - Improved read characteristics (asynchronous reads)
 - Support for aborting filesystem connection
 - POSIX file locking support
 - Request interruption support
 - Building module for Linux kernels earlier than 2.6.9 not supported
 - Allow block device based filesystems to support swap files
 - Several bugs fixed, including a rare system hang on SMP
============================================================================
What is new in 2.5
 - Merge library part of FreeBSD port
 - New atomic create+open, access and ftruncate operations
 - On filesystems implementing the new create+open operation, and
   running on Linux kernels 2.6.15 or later, the 'cp' operation will
   work correctly when copying read-only files.
 - New option parsing interface added to the library
 - Lots of minor improvements and fixes
============================================================================
What is new in 2.4
 - Simplify device opening.  Now '/dev/fuse' is a requirement
 - Allow module auto-loading if user has access to '/dev/fuse'
 - Allow mounting over a regular file for unprivileged users
 - Allow mounting of arbitrary FUSE filesystems from /etc/fstab
 - New mount options: 'umask=M', 'uid=N', 'gid=N'
 - Check for non-empty mountpoint, and refuse mount by default.  New
   mount option: 'nonempty'
 - Low level (inode based) API added
 - Allow 'direct_io' and 'keep_cache' options to be set on a
   case-by-case basis on open.
 - Add 'attr_timeout' and 'entry_timeout' mount options to the
   high-level library.  Until now these timeouts were fixed at 1 sec.
 - Some bugfixes
============================================================================
What is new in 2.3
 - Add new directory related operations: opendir(), readdir(),
   releasedir() and fsyncdir()
 - Add init() and destroy() operations which are called before the
   event loop is started and after it has exited
 - Update kernel ABI so that on dual architectures (e.g. AMD64) 32bit
   binaries work under a 64bit kernel
 - Bugfixes
============================================================================
What is new in 2.2
Userspace changes:
 - Add fuse_file_info structure to file operations, this allows the
   filesystem to return a file handle in open() which is passed to
   read(), write(), flush(), fsync() and release().
 - Add source compatibility with 2.1 and 1.4 releases
 - Binary compatibility with 2.1 release is retained
Kernel changes:
 - Make requests interruptible.  This prevents the filesystem to go
   into an unbreakable deadlock with itself.
 - Make readpages() synchronous.  Asynchronous requests are deadlock
   prone, since they cannot be interrupted (see above)
 - Remove shared-writeable mapping support, which could deadlock the
   machine
 - Remove INVALIDATE userspace initiated request
 - Update ABI to be independent of sizeof(long), so dual-size archs
   don't cause problems
 - Remove /sys/fs/fuse/version.  Version checking is now done through
   the fuse device
 - Replace directory reading method on the kernel interface.  Instead
   of passing an open file descriptor to the kernel, send data through
   the FUSE device, like all other operations.
============================================================================
What is new in 2.1
* Bug fixes
* Improved support for filesystems implementing a custom event-loop
* Add 'pkg-config' support
* Kernel module can be compiled separately
============================================================================
What is new in 1.9
* Lots of bugs fixed
* Minor modifications to the library API
* Improvements to the kernel/userspace interface

============================================================================
What is new in 1.1
* Support for the 2.6 kernels
