This file documents recent changes to MRBackup. Changes are listed in
reverse chronological/version order. The MRBackup version number
scheme follows these conventions:
The first digit is the version level. Changes in the version level
indicate major functionality changes and possible incompatibilities
with previous versions.
The second pair of digits following the period constitute the revision
level. Revisions generally indicate added or changed functionality
while maintaining upward compatibility.
If the revision level is followed by a letter (a-z), this indicates a
bug-fix release.

MRBackup Professional version 1.15 and above now REQUIRE version 2.04
(or greater) of the AmigaDOS operating system. MRBackup Professional
will no longer work on version 1.3 (or lower) of AmigaDOS.

MRBackup Professional is no longer dependent upon arp.library.
MRBackup Professional is now (again) a shareware product. While I
consider it to be of excellent commercial quality, I do not have the
resources to pursue commercial distribution. In every other aspect,
nothing has changed. If you're honest, you'll either pay the
requested registration fee or remove MRBackup from your system. I
will continue to support MRBackup Professional as long as there is
some reward in doing so.

Changes
===========
There has been some confusion over the need for a saveset catalog when
doing a restore. If you are doing a full restore, the catalog is
unnecessary. If you wish to do a partial restore, you MUST have a
catalog. Prior releases of MRBackup would let you cancel the Catalog
file requester, then ask "Restore without catalog?". This release now
presents a requester with a brief explanation and the choices "Use
Catalog, Ignore Catalog and Cancel". If you select "Use Catalog", the
catalog file requester will appear. If you select "Ignore Catalog",
MRBackup will assume that you are going to do a full restore and will
not request a catalog. If you select "Cancel", MRBackup will abort
the restore.
Several enhancements have been added to the Rebuild Catalog and
Restore commands, primarily to facilitate recovery from savesets which
are missing one or more diskettes. Also, MRBackup used to ask for
disk #1 at the beginning of a restore, even when it wasn't required.
If a diskette in a given saveset is lost or damaged, just rebuild the
catalog with whatever disks you have, then restore using that catalog.
Jeff Porter reported that MRBackup didn't work well under WorkBench
when the Screen Text font preference was set to something other than
an eight point non-proportional font. This was supposed to have been
fixed quite a while ago. Well, I've gone through all gadget
definitions and insured that Topaz 8 is explicitly referenced. There
still can be some clipping of gadgets near the top border if a large
default font is chosen, but overall the situation is much improved.

MRBackup now issues a "motor off" command to the floppy disk drive
whenever an error is detected on either a disk read or write.

===========
Bug Fixes
===========
Glenn Holliday discovered an interesting `disk full' situation when
performing an AmigaDOS backup with Formatting set to `None'. This
release fixes the problem. It should be noted, however, that this use
of MRBackup (incremental backups to the same AmigaDOS saveset) is not
really recommended unless you know all of your backed up files are
going to fit on one diskette (or hard disk partition) or you don't
care if multiple versions of a given file will accumulate over
multiple diskettes. Since MRBackup doesn't load a catalog of an
existing saveset prior to doing a backup, he doesn't know in advance
that previous versions of files may be stored on the disks being used
for this backup. Also, you'll end up with multiple catalogs, rather
than a single, consolidated catalog.
The `None' formatting option was originally added to accommodate
preformatted diskettes. While it does have other interesting uses,
you must be aware of MRBackup's limitations in these cases.
05/09/93 V1.14c
===========
Bug Fixes
===========
MRBackup could get into an error recovery loop if a file selected for
backup was deleted before it could be backed up.
Compression estimating was not working as documented. Also, to aid in
compression estimating, the final compression ratio is written to the
log file at the end of a backup.
In AmigaDOS backup mode, backup media overfull conditions can occur
through normal use, especially when using compression estimating.
MRBackup now anticipates/prevents more of these situations and handles
the ones it can't prevent in a more robust manner.
Under AmigaDOS 2.04(+), AmigaDOS backup mode, if a quick format fails
with an error 225 (ERROR_NOT_A_DOS_DISK), a normal format will be
attempted

Bug Fixes

--
The AmigaDOS mode Restore function had a serious error in its filename
construction algorithm (a side-effect of recent `minor' changes) which
effectively blocked file restoration in AmigaDOS mode (from MRBackup,
at least). The problem is fixed.
