What is new in 2.9
- Add "zero copy" support for kernel 2.6.35 or newer
- Make maximum background requests tunable on kernel 2.6.32 or newer
- Require --no-canonicalize in (u)mount (util-linux version 2.18 or
newer) to fix security problems with fusermount
- Use dynamically sized hash tables in high level library
- Memory use of filesystem daemon can shrink more easily
- Add "auto_unmount" option
- Add "remember" option
- Add man pages for fusermount, mount.fuse and ulockmgr_server
- API changes:
o Introduce "store" and "retrieve" for accessing kernel buffers on
kernel 2.6.36 or newer
o Introduce abstract buffer for zero copy operations
o Allow path calculation to be omitted on certain operations
o Allow batching forget requests
o Add "flock" method
o Add support for ioctl on directories
o Add delete notification
o Add fallocate operation (linux kernel 3.5 or newer)
- 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
* Mounting by non-root made more secure
* Build shared library in addition to the static one
* Consolidated mount options
* Optimized reading under 2.6 kernels
* Direct I/O support
* Support file I/O on deleted files
* Extended attributes support
============================================================================
What is new in 1.3
* Thanks to user bugreports and stress testing with LTP and sfx-linux
a number of bugs were fixed, some quite serious.
* Fix compile problems with recent SuSE kernles
============================================================================
What is new in 1.2
* Fix mount problems on recent 2.6 kernels with SELinux enabled
* Fixed writing files lager than 2GBytes
* Other bugfixes
============================================================================
What is new in 1.1
* Support for the 2.6 kernels
* Support for exporting filesystem over NFS in 2.6 kernels
* Read efficiency improvements: read in 64k blocks instead of 4k
(Michael Grigoriev). Can be turned on with '-l' option of fusermount

NOTE: Binaries linked with with a previous version of libavfs may
not work with the new version of the fusermount program. In such
case recompile the program after installing the new libavfs library.
