+E2fsprosg 1.11 (June 17, 1997)
+==============================
+
+Fixed e2fsck to detect (previously ignored) conflicts between the
+superblock or block group descriptors and block bitmaps, inode
+bitmaps, and inode tables.
+
+Fixed bug in e2fsck so that when the message printed out when a block
+or inode bitmap conflicts with other data, it has the correct group
+number.
+
+Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
+to badblocks. This meant that not all of the filesystem was being
+tested for bad blocks!
+
+Fixed an array boundary overrun case which cropped up in
+ext2fs_badblocks_list_test when a user tried running "mke2fs -c
+-b 4096".
+
+Adjusted the number of columns printed by mke2fs when displaying the
+superblock backups to avoid running over 80 columns when making a
+really filesystem.
+
+Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
+dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
+fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
+
+Programmer's notes:
+-------------------
+
+Fixed install rule in lib/ss so that ss_err.h is actually getting
+installed.
+
+Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
+bassed back to the caller.
+
+Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
+setting the current inode number (which meant this function wasn't
+working at all).
+
+Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
+blocks in the bitmap when increasing the size of the bitmap.
+
+Changed the initial number of blocks allocated by ext2fs_init_dblist()
+to be more realistic.
+
+Added a new function ext2fs_allocate_group_table, which sets up the
+group descriptor information (and allocates inode and block bitmaps,
+and inode tables for a particular group). The function was created by
+factoring out code form ext2fs_allocate_tables().
+
+Added a new function ext2fs_move_blocks which takes a bitmap of the
+blocks to be moved, and moves them to another location on the
+boardboard.
+
+Make the unix_io channel's io_channel_flush implementation calls sync()
+to to flush the kernel buffers to disk.
+
+Added a new function ext2fs_dblist_count returns the number of
+directory blocks in dblist.
+
+
+E2fsprogs 1.10 (April 24, 1997)
+===============================
+
+Mke2fs once again defaults to creating revision #0 filesystems, since
+people were complaining about breaking compatibility with 1.2 kernels.
+Warning messages were added to the mke2fs and tune2fs man pages that
+the sparse superblock option isn't supported by most kernels yet (1.2
+and 2.0 both don't support parse superblocks.)
+
+Added new flag to mke2fs, -R <raid options>, which allows the user to
+tell mke2fs about the RAID configuration of the filesystem. Currently
+the only supported raid option is "stride" which specifies the width
+of the RAID stripe.
+
+Fixed bug in e2fsck where pass1b would bomb out if there were any
+blocks marked bad in the inode table.
+
+Fixed rare bug in mke2fs where if the user had a very unlucky number
+of blocks in a filesystem (probability less than .002) the resulting
+filesystem would be corrupt in the last block group.
+
+Fixed bug where if e2fsck tried to allocate a block to fix a
+filesystem corruption problem and the filesystem had no free blocks,
+ext2fs_new_block() would loop forever.
+
+The configure script now checks explicitly to see if "-static" works,
+since that can't be assumed to be true --- RedHat doesn't install
+libc-static by default.
+
+Fixed bug in libext2's block iterator functions where under some
+cirmcustances, file with holes would cause the bcount parameter to the
+callback function to be incorrect. This bug didn't affect any of
+e2fsprogs programs, but it was discovered by Paul Mackerras, the
+author of the PPC boot loader.
+
+Removed use of static variables to store the inode cache in libext2fs.
+This caused problems if more than one filesystem was accessed via
+libext2fs (static variables in libraries are generally a bad idea).
+Again, this didn't affect e2fsprogs programs, but it was discovered by
+Paul Mackerras.
+
+Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
+will compile cleanly with 1.2.13 kernels (even with a.out shared
+libraries!)
+
+Programmer's notes:
+-------------------
+
+Added new functions to duplicate an ext2 filesystem handle, and its
+associated substructure. New functions: ext2fs_dup_handle(),
+ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
+Other structures, such as the io_channel and the inode_cache, now have
+a ref count so that they only get freed when they are no longer used
+by any filesystem handle. (These functions were added as part of the
+development effort for an ext2 resizer).
+
+E2fsprogs 1.09 (April 14, 1997)
+===============================
+
+Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
+accidentally introduced in the 1.08 release. The overhead calculation
+was accidentally removed, which caused ext2fs_initialize() to not
+notice when the filesystem size needed to be adjusted down because
+there wasn't enough space in the last block group.
+
+Fixed bug in version parsing library routine; it was always parsing
+the library version string, instead of using the passed-in string.
+
+Clarified chattr man page.
+
+E2fsprogs 1.08 (April 10, 1997)
+===============================
+
+E2fsck 1.07 was very slow when checking very large filesystems with a
+lot of files that had hard links (i.e., news spools). This was fixed
+by seriously revamping the icount abstraction. Added a formal test
+suite for the icount abstraction.
+
+Debugfs now has a "-l" option to the "ls" command, which lists the
+inode number, permissions, owner, group, size, and name of the files
+in the directory.
+
+Fix a bug in e2fsck where when a directory had its blocks moved to
+another location during the pass 1b processing, the directory block
+list wasn't updated, so pass 2 wouldn't check (and correct) the
+correct directory block.
+
+E2fsck will now treat inodes which contain blocks which are claimed by
+the filesystem metadata by treating them as multiply claimed blocks.
+This way, the data in those blocks can be copied to a new block during
+the pass 1b--1d processing.
+
+E2fsck will attempt to determine the correct superblock number and
+display it in the diagnostic and warning messages if possible.
+
+Add support for a new (incompatible) feature, "sparse_super". This
+feature reduces the number of blocks which contain copies of backup
+superblocks and block group descriptors. (It is only an incompatible
+feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
+support a new -s option; e2fsck will recognize filesystems built with
+this feature turned on.
+
+E2fsck now checks the library to make sure is the correct version,
+using new library functions. (This helps to diagnose incorrectly
+installed e2fsprogs distributions.)
+
+Dumpe2fs now prints more information; its now prints the the
+filesystem revision number, the filesystem sparse_super feature (if
+present), the block ranges for each block group, and the offset from
+the beginning of the block group.
+
+Mke2fs now distributes the inode and block bitmap blok so that the
+won't be concentrated in one or two disks in RAID/striping setups.
+Also, if the user chooses a 2k or 4k block group, mke2fs will try to
+choose the largest blocks per group that be chosen. (For 2k blocks,
+you can have up to 16384 blocks/group; for 4k blocks, you can have up
+to 32768 blocks/group.) Previously mke2fs would not allow
+specification of more than 8192 blocks per group, even if you were
+using a 2k or 4k block group.
+
+Programmer's notes:
+-------------------
+
+Added a new function ext2fs_create_icount2() which takes a "hint"
+argument. This hint argument presets the icount array with the list
+of inodes which actually need to be in the icount array. This really
+helps to speed up e2fsck.
+
+Added a new function ext2fs_icount_validate() which checks the rep
+invariant for the icount structure. This is used mostly for testing.
+
+The error mesasage given when a bad inode number is passed to
+test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
+EXT2FS_UNMARK_ERROR).
+
+Added a new function ext2fs_set_dir_block which sets the block of a
+dblist entry, given the directory inode and blockcnt.
+
+Added a new function ext2fs_get_library_version() which returns the
+current library version, and ext2fs_parse_version_string() which
+returns a version number based on a e2fsprogs version string.
+
+The icount functions will return EINVAL if the passed in inode number
+is out of bounds.
+
+E2fsprogs 1.07 (March 9, 1997)
+==============================
+
+E2fsck is now uses much less memory when checking really large
+filesystems (or rather, filesystems with a large number of inodes).
+Previously a filesystem with 1 million inodes required 4 megabytes of
+memory to store inode count statistics; that storage requirement has
+now been reduced to roughly half a megabyte.
+
+E2fsck can now properly deal with bad blocks appearing inside the
+inode table. Instead of trying to relocate the inode table (which
+often failed because there wasn't enough space), the inodes in the bad
+block are marked as in use.
+
+E2fsck will automatically try to use the backup superblocks if the
+primary superblocks have a bad magic number or have missing meta-data
+blocks (or meta-data blocks which are out of range).
+
+E2fsck's pass 3 has been made more efficient; most noticeable on
+filesystems with a very large number of directories.
+
+Completely revamped e2fsck's system of printing problem reports. It
+is now table driven, to make them more easily customizeable and
+extendable. Error messages which can be printed out during preen mode
+are now one line long.
+
+Fixed e2fsck's filesystem swapping code so that it won't try to swap
+fast symbolic links or deleted files.
+
+Fixed e2fsck core dumping when fixing a filesystem which has no
+directories (not even a root directory).
+
+Added a check to e2fsck to make sure that the length of every
+directory entry is a multiple of 4 (since the kernel complains if it
+isn't).
+
+Added a check to e2fsck to make sure that a directory entry isn't a
+link to the root directory, since that isn't allowed.
+
+Added a check to e2fsk to now make sure the '.' and '..' directory
+entries are null terminated, since the 2.0 kernel requires it.
+
+Added check to write_bitmaps() to make sure the superblock doesn't get
+trashed if the inode or block bitmap is marked as being block zero.
+
+Added checking of the new feature set fields in the superblock, to
+avoid dealing with new filesystem features that this package wasn't
+set up to handle.
+
+Fixed a fencepost error in ext2fs_new_block() which would occasionally
+try to allocate a block beyond the end of a filesystem.
+
+When the UUID library picks a random IEEE 802 address (because it
+can't find one from a network card), it sets the multicast bit, to
+avoid conflicting with a legitimate IEEE 802 address.
+
+Mke2fs now sets the root directory's owner to be the real uid of the
+user running mke2fs. If the real uid is non-zero, it also sets
+the group ownership of the root directory to be the real group-id of
+the user running mke2fs.
+
+Mke2fs now has more intelligent error checking when it is given a
+non-existent device.
+
+When badblocks is given the -vv option, it now updates the block that
+it is currently testing on every block.
+
+Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
+currently correctly if PATH wasn't already set.
+
+Shared libraries now built with dependencies. This allows the shared
+library files to be used with dlopen(); it also makes the transition
+to libc 6 easier, since ld.so can tell which libc a particular shared
+library expects to use.
+
+Programmer's notes:
+-------------------
+
+Added new abstraction (defined in dblist.c) for maintaining a list of
+blocks which belongs to directories. This is used in e2fsck and other
+programs which need to iterate over all directories.
+
+Added new functions which test to see if a contiguous range of blocks
+(or inodes) are available. (ext2fs_*_bitmap_range).
+
+Added new function (ext2_inode_has_valid_blocks) which returns true if
+an inode has valid blocks. (moved from e2fsck code).
+
+Added new function (ext2fs_allocate_tables) which allocates the
+meta-data blocks as part of initializing a filesystem. (moved from
+mke2fs code).
+
+Added a new I/O manager for testing purposes. It will either allow a
+program to intercept I/O requests, or print debugging messages to
+trace the activity of a program using the I/O manager.
+
+The badblocks_list functions now store the bad blocks in a sorted
+order, and use a binary search to speed up badblocks_list_test.
+
+The inode scan function ext2fs_get_next_inode() may now return a soft
+error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
+those cases where part of an inode table is missing or there is a bad
+block in the inode table.
+
+Added a new function (ext2fs_block_iterate2) which adds new arguments to
+the callback function to return a pointer (block and offset) to the
+reference of the block.
+
+Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
+application to jump to a particular block group while doing an inode
+scan.
+
+The badblocks list functions were renamed from badblocks_* to
+ext2fs_badblocks_*. Backwards compatibility functions are available
+for now, but programs should be modified to use the new interface.
+
+Some of the library functions were reorganized into separate files to
+reduce the size of some programs which statically link against the
+ext2 library.
+
+Put in some miscellaneous fixes for the Alpha platform.
