+Unreleased Changes
+==================
+
+* The channel interface (``fuse_chan_*`` functions) has been
+  made privat. The `struct fuse_chan_ops` data structure is now
+  opaque.
+
+* Added *clone_fd* option.  This creates a separate device file
+  descriptor for each processing thread, which might improve
+  performance.
+
+* The (high- and low-level) `rename` handlers now takes a *flags*
+  parameter (with values corresponding to the *renameat2* system call
+  introduced in Linux 3.15).
+
+* The "ulockmgr_server" has been dropped.
+
+* There is a new (low-level) `readdirplus` handler, with a
+  corresponding example in ``examples/fuse_lo-plus.c`` and a new
+  `fuse_add_direntry_plus` API function.
+
+* The (high-level) `readdir` handler now takes a *flags* argument.
+
+* The (high-level) `filler` function passed to `readdir` now takes an
+  additional *flags* argument.
+
+* The (high-level) `getdir` handler has been dropped.
+
+* The *flag_nullpath_ok* and *flag_utime_omit_ok* flags have been
+  dropped.
+
+* The (high-level) *utime* handler has been dropped.
+
+* The `fuse_invalidate` function has been removed.
+
+* The `fuse_is_lib_option` function has been removed.
+
+* The *fh_old* member of `struct fuse_file_info` has been dropped.
+
+* The type of the *writepage* member of `struct fuse_file_info` was
+  changed from *int* to *unsigned int*.
+
+* The `struct fuse_file_info` gained a new *poll_events* member.
+
+* There is a new `fuse_pkgversion` function.
+
+* The *fuse_off_t* and *fuse_ino_t* changed from *unsigned long* to
+  *uint64_t*, i.e. they are now 64 bits also on 32-bit systems.
+
+* The type of the *generation* member of `struct fuse_entry_param*
+  changed from *unsigned* to *uint64_t*.
+
+* The (low-level) `setattr` handler gained a *FUSE_SET_ATTR_CTIME* bit
+  *for its *to_set* parameter.
+
+* The `struct fuse_session_ops` data structure has been dropped.
+
+* The documentation has been clarified and improved in many places.
+
+
+FUSE 2.9.7 (2016-06-20)
+=======================
+
+* Added SELinux support.
+* Fixed race-condition when session is terminated right after starting
+  a FUSE file system.
+
+FUSE 2.9.6 (2016-04-23)
+=======================
+
+* Tarball now includes documentation.
+* Shared-object version has now been bumped correctly.
+
+FUSE 2.9.5 (2016-01-14)
+=======================
+
+* New maintainer: Nikolaus Rath <Nikolaus@rath.org>. Many thanks to
+  Miklos Szeredi <miklos@szeredi.hu> for bringing FUSE to where it is
+  now!
+
+* fix warning in mount.c:receive_fd().  Reported by Albert Berger
+
+* fix possible memory leak.  Reported by Jose R. Guzman
+
+FUSE 2.9.4 (2015-05-22)
+=======================
+
+* fix exec environment for mount and umount.  Found by Tavis Ormandy
+  (CVE-2015-3202).
+
+* fix fuse_remove_signal_handlers() to properly restore the default
+  signal handler.  Reported by: Chris Johnson
+
+* highlevel API: fix directory file handle passed to ioctl() method.
+  Reported by Eric Biggers
+
+* libfuse: document deadlock avoidance for fuse_notify_inval_entry()
+  and fuse_notify_delete()
+
+* fusermount, libfuse: send value as unsigned in "user_id=" and
+  "group_id=" options.  Uids/gids larger than 2147483647 would result
+  in EINVAL when mounting the filesystem.  This also needs a fix in
+  the kernel.
+
+* Initilaize stat buffer passed to ->getattr() and ->fgetattr() to
+  zero in all cases.  Reported by Daniel Iwan
+
+* libfuse: Add missing includes.  This allows compiling fuse with
+  musl.  Patch by Daniel Thau
+
+
