Version 1.17b

  * Completed the implementation for `hattrib'; HFS file attributes (type,
    creator, invisible/locked) can now be changed from the command line.

  * Fixed an off-by-one error in computing catalog record key lengths.

  * Fixed a problem with backslash-quoted braces during globbing.

  * Improved Makefile handling.

  * Regularized the handling of the volume-unmounted flag.

  * Streamlined the internal and external interface header files.

  * Added a `parid' field to the hfsdirent structure.

  * Updated libhfs documentation.

  * Implemented a better error message reporting format involving pathnames.

Version 1.16b

  * Improved the robustness of the HFS path resolution routine.

  * Fixed hfs_rename() to better detect the validity of destination paths.

  * Changed mount-time scavenging only to mark bits in the volume bitmap,
    not clear them. This reduces the risk of causing further damage to a
    corrupt disk, leaving serious recovery to more advanced tools.

  * Added file locking to hfs_mount() to prevent concurrent processes from
    potentially creating inconsistencies in a volume.

  * Added a new argument to hfs_mount() for specifying mount flags. This now
    allows a volume to be explicitly mounted read-only, read-write, or don't
    care (whichever is available).

  * Improved detection and handling of multiple same-device mounts by a single
    process.

  * Improved error message reporting for all programs.

  * Fixed a problem where hrenaming a volume caused it to become inaccessible
    until it was hmounted again.

Version 1.15b

  * Increased buffer size for native HFS-to-HFS copies to increase
    performance.

  * Fixed a problem verifying the existence of directory threads.

  * Fixed a problem with the handling of catalog and extents clump sizes.

Version 1.14b

  * The command-line programs now support filename globbing; see hfsutils(1)
    for syntax details.

  * File threads are now managed properly when the associated file is deleted,
    moved, or renamed. However, there is no mechanism yet to explicitly create
    or remove threads, or to use them in catalog searches.

  * The volume bitmap is now reconstructed from the catalog and extents files
    when a volume is mounted that was not previously cleanly unmounted.

  * Directories may now be deleted recursively using `xhfs'.

  * BinHex and MacBinary header fork size validation limitations have been
    relaxed. (MacBinary spec suggested 0x007fffff ~= 8MB as maximum length?)

  * Volumes are now flushed automatically by `xhfs' every 30 seconds to
    reduce risk of accidental data loss.

  * Begun work on `hfsck', a program to verify and correct HFS volume
    consistency.

  * Begun work on `librsrc', a library for manipulating the resource forks
    of HFS files.

Version 1.13b

  * Fixed two bad extent record key sorting bugs; these could have caused
    serious problems on certain fragmented volumes.

  * Fixed a problem related to MacOS default file clump size semantics.

  * Implemented recursive directory copies in `xhfs'.

  * Files and directories may now be renamed with a mere change of case.

  * Multiple files may now be moved with `hrename'.

  * A UNIX pathname of "-" in `hcopy' may now be used to mean stdin or stdout
    when used as the source or destination target, respectively.

Version 1.12b

  * Fix to allow mounting of some miscreant partitioned media.

  * Increased copyin/copyout buffer sizes for better performance.

  * Implemented -a for `hcopy' (automatic transfer mode selection.)

  * HFS timestamps are now relative to the current time zone.

Version 1.11b

  * UNIX-to-HFS BinHex transfers have been implemented. All transfer modes
    are now fully implemented.

  * The overall BinHex implementation now uses the stdio library for
    somewhat better performance.

  * New libhfs routines: hfs_setattr(), hfs_fsetattr() for changing file
    and directory attributes (timestamps, type/creator, flags).

  * The copyin routines now update the relevant file information (timestamps,
    flags) for MacBinary and BinHex transfers.

  * The `hvol' command now provides better output.

  * Modified the installation procedure; separate targets now build and
    install the separate components of the package.

  * Fixed a bug in HFS filename sorting which affects the search routines;
    filenames are now sorted precisely according to MacOS idiosyncrasies.

  * Begun work on (but still unimplemented): hattrib, filename globbing.

Version 1.10b

  * Fixed a serious bug in directory record updates; directories with names
    longer than 21 characters could get corrupted.

  * Implemented hfs_rename() and eliminated hfs_move(); functionality for
    the latter has been included in the former.

  * Added an `hrename' command. Minor changes to hcwd.c to cope with
    volume name or cwd path changes.

  * Minor changes to `xhfs'. Files can now be renamed with the interface.

Version 1.9b

  * Modularized the libhfs code.

  * Resolved more portability issues. The code should now work regardless of
    the size or endianness of the host's datatypes.

Version 1.8.1b

  * Fixed some portability bugs.

Version 1.8b

  * More UI enhancements to `xhfs'.

  * UNIX-to-HFS MacBinary II transfers have been implemented; HFS-to-HFS
    copies have been implemented. Only one transfer mode (UNIX-to-HFS BinHex)
    remains unimplemented.

  * Replaced `hcat' with a generic `hcopy'. All transfer modes are supported.
    (But note: The -a option is not yet supported.)

  * Fixed a bug in the MacBinary II encoding CRC algorithm.

  * Tcl hash tables are now used to maintain open files and volumes.

  * Cleaned up some of the Tcl/Tk interface to aid compatibility with
    various versions.

Version 1.7b

  * Many more UI enhancements to `xhfs'.

  * Files can now be copied from UNIX to HFS volumes with `xhfs' using either
    Text or Raw mode translation.

Version 1.6b

  * Fixed a bug in the catalog manipulation routines which would allow files
    and directories to be created at the same level as the root folder.

  * Many UI enhancements to `xhfs'. Some minor enhancements to `hfs'.

  * hfs_islocked() now returns 1 if a volume is locked (read-only).

  * Extended file attributes to recognize invisible files.

Version 1.5b

  * All cases of B*-tree record insertion have been completed.

  * B*-tree record deletion has been implemented. Files and folders may now
    be created and deleted with no limitations (other than the size of the
    volume.)

  * New commands: hrmdir, hdel

  * File writing and truncation have been implemented.

  * The library now maintains its own concept of "current volume". The last
    volume to be mounted is by default current; the new functions
    hfs_getvol() and hfs_setvol() can be used to get and set the current
    volume, respectively. All other functions will now accept a null volume
    pointer to represent the current volume.

  * Absolute pathnames may now refer to (mounted) volumes other than the one
    specified in the call; in this event the specified volume is ignored.

Version 1.4b

  * Updated the installation procedure. The Tcl and Tk programs can now be
    built and installed optionally.

  * Fixed a minor bug which would cause the header node to be read just
    before completing a directory read.

  * Mounting the same volume more than once now returns a reference to the
    same volume, and does the right thing when each reference is
    independently unmounted.

  * Cleaned up some of the Tcl interface to deal with multiply-referenced
    volumes. `xhfs' can now deal with the same volume on both sides.

  * Renamed hfs_cwdid() to hfs_getcwd(), and added hfs_setcwd().

  * hfs_umount() now closes all open files and directories on the volume
    before unmounting it. All external references to the volume and any
    open files/directories will become invalid.

  * Enabled hfs_umountall() which will effectively unmount all volumes,
    invalidating all external volume and file references. This is a
    catch-all that should be called before a program exits. N.B.: Errors
    during volume flushing and unmounting are not reported.

Version 1.3b

  * Enhanced writability: B*-tree file growth has been implemented. New
    directories can be created until the disk gets full. 

  * Added an option to `xhfs' for creating new directories.

Version 1.2b

  * Enhanced writability: B*-tree node splitting has been implemented. New
    directories can be created until the catalog file gets full.

  * Fixed some minor bugs in version 1.1b.

Version 1.1b

  * Full read-only capability.

  * Limited write capability: new directories can be created only until
    a catalog node gets full.

  * New volumes can be created with hfs_format().
