	* kernel: add necessary compile flags for 2.4.X/x86_64.
	Report from Sean Ziegeler

2006-01-09  Miklos Szeredi <[e-mail]>

	* Released 2.5.0-pre2

2006-01-09  Miklos Szeredi <[e-mail]>

	* Applied patch from Csaba Henk, to update mount_bsd to new
	fuse_mount() semantics

	* Ignore auto,noauto,... options in mount.fuse.  Reported by Frank
	Steiner and Don Taber

	* fusermount: add 'dirsync' mount option

2006-01-07  Miklos Szeredi <[e-mail]>

	* Improved help reporting and added version reporting to library

2006-01-06  Miklos Szeredi <[e-mail]>

	* Change working directory to "/" even if running in the
	foreground.  Patch from Jonathan Brandmeyer

	* Changed lots of functions to use 'struct fuse_args' instead of
	separate argc and argv

	* Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
	fuse_remove_signal_handlers() functions, so that it's now pretty
	easy to get all the functionality of fuse_main() with a filesystem
	using the lowlevel API.

2006-01-02  Miklos Szeredi <[e-mail]>

	* mount.fuse: the 'user' option should be ignored. Report and
	solution from Mattd.

	* mount.fuse: export PATH in the right place. Report and patch
	from Hannes Schweizer

2005-12-16  Miklos Szeredi <[e-mail]>

	* Clean up the option parsing interface slightly, by creating an
	"argument list" structure, that contains the argument vector and
	count

2005-12-15  Miklos Szeredi <[e-mail]>

	* fusermount: check if /mnt/mtab is a symlink and don't modify it
	in that case

	* kernel: simplify request size limiting. INIT only contains
	maximum write size, maximum path component size remains fixed at
	1024 bytes, and maximum xattr size depends on read buffer.

2005-12-14  Miklos Szeredi <[e-mail]>

	* Fix readdir() failure on x86_64, of 32bit programs compiled
	without largefile support.  Bug report and help from Anthony
	Kolasny

	* If lookup returns invalid mode, return -EIO instead of creating
	a regular file

	* Add current output argument vector to option processing
	function

2005-12-12  Miklos Szeredi <[e-mail]>

	* Fix stale code in ifdef FreeBSD.  Patch from Csaba Henk

2005-12-09  Miklos Szeredi <[e-mail]>

	* Released 2.5.0-pre1

2005-12-09  Miklos Szeredi <[e-mail]>

	* libfuse: added option parsing interface, defined in
	<fuse_opt.h>.

2005-12-07  Miklos Szeredi <[e-mail]>

	* Return EIO for file operations (read, write, fsync, flush) on
	open files whose inode has become "bad".  Inodes will be marked
	"bad" if their type changes.  Bug report by Csaba Henk

2005-12-06  Miklos Szeredi <[e-mail]>

	* Use bigger request buffer size.  write() did not work on archs
	with > 4k page size, Bug report by Mark Haney

	* ABI version 7.5:

	* Extend INIT reply with data size limits

2005-12-02  Miklos Szeredi <[e-mail]>

	* Fix memory leak in fuse_read_cmd()/fuse_process_cmd().  Bug
	reported by Vincenzo Ciancia

	* Handle exit-by-umount in fuse_read_cmd()

2005-11-29  Miklos Szeredi <[e-mail]>

	* Check if '-msoft-float' option is supported by compiler when
	configuring for a 2.4.x kernel.  Bug report by Mark Haney

	* In multithreaded loop send a TERM signal to the main thread if
	one of the other threads exit.  Needed on FreeBSD for a clean exit
	on umount.  Should not cause any harm on Linux either

2005-11-28  Miklos Szeredi <[e-mail]>

	* Fix bug in 32-bit file handle compatibility

2005-11-27  Miklos Szeredi <[e-mail]>

	* Block TERM, INT, HUP and QUIT signals in all but the main
	thread.  According to POSIX it's not specified which thread will
	receive these signals.

	* Kernel changes:

	* Check for directory aliasing on mkdir, not just on lookup

	* Check for special node ID values in create+open operation

	* Sync with -mm: readv, writev, aio_read and aio_write methods
	added to file operations

	* Cleanups: lookup code, page offset calculation

	* ABI stepped to 7.4, changes:

	* frsize member added to fuse_kstatfs structure

	* added support for negative entry caching: on lowlevel API if
	fuse_entry_param::ino is set to zero in reply to a lookup request,
	the kernel will cache the dentry for the specified amount of time.

	* libfuse: added 'negative_timeout' option: specifies how much
	negative entries should be cached.  Default is zero, to be
	compatible with prior versions

2005-11-22  Miklos Szeredi <[e-mail]>

	* Add detection of mainline FUSE code in running kernel

2005-11-21  Miklos Szeredi <[e-mail]>

	* Don't use async cancelation in multithreaded loop.  This makes
	it more portable to systems where read() is not async cancel safe.
	Report from Andriy Gapon

2005-11-20  Miklos Szeredi <[e-mail]>

	* Warn if API version 11 compatibility is requested

2005-11-17  Miklos Szeredi <[e-mail]>

	* More FreeBSD merge

	* fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
	them, because it corrupts /etc/mtab.  Found by Thomas Biege
	CVE-2005-3531

	* libfuse: don't use system() to invoke 'fusermount -u ...'
	because it breaks mountpoints with spaces in them into multiple
	arguments

2005-11-16  Miklos Szeredi <[e-mail]>

	* Merge library part of FreeBSD port.  Patch by Csaba Henk

2005-11-11  Miklos Szeredi <[e-mail]>

	* Use 64bit type for file handle, so the full range supported by
	the kernel interface is available to applications

2005-11-10  Miklos Szeredi <[e-mail]>

	* Moved mountpoint argument checking from fuse_parse_cmdline() to
	fuse_mount() in preparation to FreeBSD merge.

2005-11-08  Miklos Szeredi <[e-mail]>

	* Remove unneeded close() from fuse_teardown().  Spotted by Csaba
	Henk.

2005-11-07  Miklos Szeredi <[e-mail]>

	* Make the statfs change backwards compatible.

2005-11-06  Miklos Szeredi <[e-mail]>

	* Change ->statfs() method to use 'struct statvfs' instead of
	'struct statfs'.  This makes the API more portable since statvfs()
	is defined by POSIX.

2005-10-28  Miklos Szeredi <[e-mail]>

	* Add fgetattr() method, which currently will only be called after
	a successful call to a create() method.

2005-10-26  Miklos Szeredi <[e-mail]>

	* Change kernel ABI version to 7.3

	* Add ACCESS operation.  This is called from the access() system
	call if 'default_permissions' mount option is not given, and is
	not called on kernels 2.4.*

	* Add atomic CREATE+OPEN operation.  This will only work with
	2.6.15 (presumably) or later Linux kernels.

	* Add ftruncate() method.  This will only work with 2.6.15
	(presumably) or later Linux kernels.

	* Fix kernel module compile if kernel source and build directories
	differ.  Report and initial patch by John Eastman

2005-10-18  Miklos Szeredi <[e-mail]>

	* lib: optimize buffer reallocation in fill_dir.

2005-10-17  Miklos Szeredi <[e-mail]>

	* Released 2.4.1

	warnings for too large read/write result

2005-10-11  Miklos Szeredi <[e-mail]>

	* Spelling fixes, thanks to Ioannis Barkas

2005-10-10  Miklos Szeredi <[e-mail]>

	patch

2005-10-07  Miklos Szeredi <[e-mail]>

	* highlevel-lib: init() and destroy() methods didn't have an
	initialized fuse_context.  Bug reported by Tim Stoakes

2005-10-04  Miklos Szeredi <[e-mail]>

	* Released 2.4.0

2005-10-03  Miklos Szeredi <[e-mail]>

	* API cleanups:

	* Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME

	* Move fuse_mount() and fuse_unmount() to fuse_common.h

	* Change the return type of fuse_reply_none() from int to void.

2005-09-30  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-rc1

2005-09-26  Miklos Szeredi <[e-mail]>

	* fusermount: allow user umount in the case when /etc/mtab is a
	symlink to /proc/mounts.  Reported by Balázs Pozsár.

2005-09-23  Miklos Szeredi <[e-mail]>

	* Check for special node ID values in lookup and creation

2005-09-22  Miklos Szeredi <[e-mail]>

	* Slight optimization in returning EINVAL error in case of an open
	with O_DIRECT flag.

2005-09-20  Miklos Szeredi <[e-mail]>

	* Remove '--enable-auto-modprobe' configure flag.  Module
	auto-loading is now handled by the kernel.

2005-09-15  Miklos Szeredi <[e-mail]>

	* Install UDEV rule file, so /dev/fuse is created with mode 0666.
	Help from Jens M. Noedler.

2005-09-14  Miklos Szeredi <[e-mail]>

	* Add memory cleanup on thread exit

2005-09-13  Miklos Szeredi <[e-mail]>

	* Set umask to zero in fusexmp and fusexmp_fh, so that
	files/directories are created with the requested mode.

2005-09-12  Miklos Szeredi <[e-mail]>

	* Don't ignore read error in multithreaded loop

2005-09-08  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-pre2

2005-09-08  Miklos Szeredi <[e-mail]>

	* Revert lock and access operations.  Postpone these until 2.5.

2005-09-02  Miklos Szeredi <[e-mail]>

	* Fix compile warning on 2.6.13 and later

	* Fix compilation on old kernels

2005-08-19  Miklos Szeredi <[e-mail]>

	* lib: always refresh directory contents after rewinddir() to
	conform to SUS.  Bug found by John Muir.

2005-08-15  Miklos Szeredi <[e-mail]>

	* Released 2.4.0-pre1

2005-08-14  Miklos Szeredi <[e-mail]>

	* lib: cleaned up (or messed up, depending on your POV) the low
	level library API.  Hopefully this is close to the final form.

2005-08-05  Miklos Szeredi <[e-mail]>

	* fusermount: don't allow empty mountpoint argument, which defeats
	automatic umounting in fuse_main().  Bugreport by Václav Jůza

2005-08-03  Miklos Szeredi <[e-mail]>

	* fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
	option is used (Paul Alfille).

2005-08-02  Miklos Szeredi <[e-mail]>

	* highlevel-lib: added mount options "attr_timeout" and
	"entry_timeout".  These options control the length of time file
	attributes and entries (names) are cached.  Both default to 1.0
	second.

	* kernel: correctly handle zero timeout for attributes and entries

2005-08-01  Miklos Szeredi <[e-mail]>

	* Added missing symbols to versionscript (Joshua J. Berry)

	* kernel: implement two flags, open can set: 'direct_io' and
	'keep_cache'.  These correspond exactly to mount options
	'direct_io' and 'kernel_cache', but allow a per-open setting.

	* Move 'direct_io' and 'kernel_cache' mount option handling to
	userspace.  For both mount options, if the option is given, then
	the respective open flag is set, otherwise the open flag is left
	unmodified (so the filesystem can set it).

	* lib (highlevel): make open method optional

2005-07-28  Miklos Szeredi <[e-mail]>

	* kernel: invalidate attributes for read/readdir/readlink
	operations
