2019-08-23 John Elliott
* libdsk-1.5.12 released.
* LDBS driver: Fixed geometry probe when dealing with non-power-of-2
sector sizes.
2019-07-27 John Elliott
* libdsk-1.5.11 released.
2019-07-20 John Elliott
* New driver: dc42 (for Apple DiskCopy 4.2 disk images. This
required an update to LDBS to support GCR encoding, so the
LDBS format now stands at version 0.4. This should be forward-
and backward-compatible with existing files in LDBS 0.3 format.
2019-07-06 John Elliott
* QRST: Added transparent decompression for QRST v5 disk images.
* Gotek driver: Added support for 720k disk image collections
(as written by the SFRM72-TU100K firmware)
2019-02-17 John Elliott
* dsk_getgeom(): Added rudimentary support for detecting Apple
HFS 1.4Mb format. This allows dsklabel and lsgotek to display
the labels of Apple-format disc images.
Support for 400k and 800k formats is going to have to wait until
I can work out how to represent them in a DSK_GEOMETRY structure!
* Gotek driver: Added the ability to select which drive image is
current without closing and reopening (using the driver-specific
option GOTEK:PARTITION). This should improve performance of
lsgotek under Windows.
2019-01-17 John Elliott
* libdsk-1.5.10 released.
2019-01-01 John Elliott
* dsktrans, dskform, dskdump: Output filetype always defaulted to
'dsk'. Attempt to come up with a reasonable default based on
the filename (which can be overridden if required)
* The compression type 'none' can be used to disable auto-expansion
of compressed disc images (necessary if you are writing compressed
data such as the Slackware installer without decompression).
* Geometry probe: Rewrite the DFS boot block check so that LibDsk
has a sporting chance of detecting DFS-format media.
* New utility: dsklabel (get / set label on DOS, CP/M or DFS media)
* New utility: lsgotek (list the drive images on a Gotek-format USB
drive)
* New driver: gotek (allows access to Gotek-format drive emulation
disc images stored on a USB key)
* More bug fixes from Mark Ogden: Incorrect results returned by the
geometry probe in LDBS-based formats, and accessing sectors with
dsk_lread() on disc images with 'extended surface' layout.
* dskutil: Swapped "sectors / track" and "sectors / cylinder"
captions (Mark Ogden).
* Fixed some memory corruption issues detected by VS2017 analysis
(Mark Ogden).
* dskform: Widened total_sectors32 to 32 bits (Mark Ogden).
* apridisk: Fixed a crash writing to Apridisk files.
2018-09-18 John Elliott
* libdsk-1.5.9 released.
* Fixed compilation issue on recent glibc (Steven Fosdick).
* dskform: Added -pcdos and -apricot options to create FAT12
filesystems.
2018-04-09 John Elliott
* SAP: New disk image format implemented (Thanks to Emulix75).
2018-02-06 John Elliott
* libdsk-1.5.8 released.
* Teledisk driver: Drive type guesser had types 1 and 2 (5.25" 48tpi
and 96tpi) round the wrong way.
2018-01-31 John Elliott
* libdsk-1.5.7 released.
* Teledisk driver: Improved drive type guesser to cope with FM
recording, sector sizes other than 512, extended-surface format
discs.
2018-01-26 John Elliott
* libdsk-1.5.6 released.
* Teledisk driver: Make a stab at guessing the drive type when
converting a disk image to Teledisk format.
2018-01-10 John Elliott
* Geometry probe: Change the behaviour so that dsk_getgeometry()
on a raw-format disc image of a DOS 1.4M disc comes up with
the correct data rate.
2017-10-29 John Elliott
* libsk-1.5.5 released.
* POSIX: Integer underflow when formatting a track, causing a
file of infinite size to be written.
* POSIX: Sanity-check sector numbers passed to the driver,
for another integer underflow.
2017-03-14 John Elliott
* DSK: Rewritten to support Simon Owen's 'Offset-Info' extension.
DSK files using Offset-Info cannot be readily rewritten
in-place, so the DSK driver now uses LDBS as an intermediate
format.
* LDBS: In order to support the 'Offset-Info' extension properly,
the LDBS file format has changed and the reference
implementation updated accordingly. LDBS files generated by
previous versions of LibDsk are still supported for now.
2017-03-03 John Elliott
* New backend: Compaq QRST (Quick Release Sector Transfer).
* New utility: dskconv -- convert a disc image file from one format
to another using LDBS as an intermediate format.
* ApriDisk, CFI, IMD, JV3, CopyQM and TeleDisk: All these drivers
have been rewritten to use LDBS for intermediate storage,
rather than each one using its own internal storage system.
* All drivers: Driver names now allow aliases (eg, 'td0' as a synonym
for 'teledisk').
* Win16 port no longer supports TeleDisk or CopyQM drivers (Win16
DLLs have not access to sscanf() )
2016-11-01 John Elliott
* libdsk-1.5.2 released. Changes from libdsk 1.4.2 merged:
* Geometry probe: Make the Apricot BPB check more discerning.
* IMD: Support IMD files with no comment (header line is followed
immediately by 0x1A).
* IMD: Fixed segfault when writing IMD file if number of tracks is not
20,40,80 or 160.
2016-03-18 John Elliott
* libdsk-1.5.0 released.
* New driver: LDBS ('LibDsk Block Store'), a new disc image
format under development.
2015-12-28 John Elliott
* libdsk-1.4.1 released.
* General: Added a 'complement' flag to the recording mode,
allowing support of disk images where all bytes are stored
complemented.
2015-12-15 John Elliott
* OK, let's call it stable: libdsk-1.4.0 released.
2015-05-01 John Elliott
* libdsk-1.3.9 released.
* New backend: JV3 (for TRS-80 'JV3' disc images). These have no
magic number, so must be specified manually.
2015-04-24 John Elliott
* libdsk-1.3.8 released.
* IMD bugfix: Geometry probe was returning an incorrect data rate
for HD disks.
2015-04-21 John Elliott
* libdsk-1.3.7 released.
* New geometry type added: "extsurface", for discs where the sector
numbers increase across both sides (eg: 1-9 on side 0, 10-18 on
side 1).
* New backend: IMD (for files created by ImageDisk). Read/write
support. Also has a built-in extra geometry probe, which may be worth
pushing to other drivers (eg: DSK, TD0) that carry a similar amount
of detail.
2015-01-06 John Elliott
* Configure script: winioctl.h was not being detected. Also
updated to autoconf 2.69
* dsk_getgeom: Fixed C89 compilation issue.
2014-03-02 John Elliott
* libdsk-1.3.5 released.
* Teledisk: Added read-only support for 'advanced' compression.
Based on wteledsk decompression code by Will Kranz (relicensed
under LGPLv2, with permission).
* Teledisk: Check CRC of header before opening disk image.
* dg_stdgeom(): Built-in geometry specifications were out of step
with the corresponding dsk_format_t numbers. This wouldn't have
affected setting formats by name, but some of the automatic geometry
probes could have returned an incorrect geometry.
* dsk_getgeom(): Added four Ampro formats: ampro200, ampro400d,
ampro400s and ampro800. These correspond to formats AMP1-AMP4
under 22DISK. The double-sided ones can be autodetected by
dsk_getgeom(); sadly, the single-sided ones can't.
* dsk_typedesc_enum(): New function to enumerate driver
descriptions without needing to open a disk image in each
format in turn.
* Utilities: All utilities now take options '-types' and '-formats'
to list supported drivers and disk formats.
* dsktest: New -libdskrc argument to dump all known disk formats
in .libdskrc format.
2014-03-01 John Elliott
* libdsk-1.3.4 released.
* Documentation fix: 'teledisk' -> 'tele'
* Included an example .libdskrc file.
* Set the dirty flag when a drive comment is changed.
2011-04-20 John Elliott (based on patches from Ralf-Peter Nerlich)
* Replacement CopyQM driver
* All utilities now use basename() (if available) to trim paths
from argv[0]
2011-03-29 John Elliott
* dsk_creat: Check that this method is implemented before calling it.
* dskutil: Correct the description of the 'W' command (Ralf-Peter
Nerlich)
2011-01-10 John Elliott
* rcpmfs: Added support for the ISX variant of the CP/M 2 format.
2010-09-27 John Elliott
* libdsk-1.3.3 released.
* rcpmfs: Buffer overflow when renaming a file with a full 8.3 name
and a nonzero user number. [Thanks to Jurgen Sievers]
2010-06-28 John Elliott
* Updated to latest autotools, various compiler warnings fixed.
2009-11-07 John Elliott
* libdsk-1.3.2 released.
2009-11-07 Jacob Nevins
* CFI format: Ensure that status messages are correctly removed.
2009-05-14 John Elliott
* Geometry probe: Support Opus Discovery disks.
2008-12-26 John Elliott
* Linux floppy driver: Do an FDCLRPRM when opening the floppy drive.
This seems to be necessary to force a seek on the first read.
[Thanks to Stewart Kay]
2008-08-24 John Elliott
* CPCEMU format: Corrected a problem with signed/unsigned integer
comparison.
2008-08-16 John Elliott
* Fixed some compiler warnings under 16-bit DOS.
* Added a -comment option to dsktrans, allowing the comment to be
set when disks are imaged.
2008-06-07 John Elliott
* libdsk-1.3.0 released.
* Added support for SIMH disc image format.
2008-06-01 John Elliott
* Added support for YAZE ydsk format.
* Added skeletal support for IBM dskf format (not yet functional).
* Added knowledge of filesystem parameters, since both the above
formats require these as part of their metadata.
2008-04-02 Alistair John Bush
* Patched Makefile.am to pass JAVACFLAGS to Java compiler.
2008-01-23 John Elliott
* libdsk-1.2.1 released.
2008-01-19 Sven Klose
* Corrected a compilation problem on FreeBSD.
2008-01-12 John Elliott
* Corrected a bug which caused rcpmfs to give 'overrun' errors
when emulating a CP/M 2 filesystem.
2007-12-17 John Elliott
* libdsk-1.2.0 released.
2007-12-10 John Elliott
* Removed O_CREAT from attempts to open serial ports.
* For some reason I commented out the ibm320 format between
libdsk-1.1.2 and libdsk-1.1.3. Can't think why. Uncommented it.
* Removed a couple of C99 style comments (//) which prevented
compilation on really old gcc versions.
2007-07-27 John Elliott
* libdsk-1.1.14 released.
2007-06-11 Stuart Brady
* Added a new geometry (FMT_TRDOS640).
2007-06-10 John Elliott
* Updated the DOS and Windows projects with the new drivers
(the Teledisk one didn't compile under Win16).
2007-06-09 John Elliott
* libdsk-1.1.13 released.
* New driver: Logical. This is a raw disc image as generated by
'dsktrans -logical'; that is, it is arranged in logical sector order
rather than SIDES_ALT order. Useful for dealing with raw disc images
that were dumped in logical order.
* dsktrans: The -logical option has accordingly been deprecated,
since '-otype logical' should have the same effect.
2007-06-02 John Elliott
* New driver: Teledisk, based on the file format documentation at
<http://www.fpns.net/willy/wteledsk.htm>. This driver is read-only.
No code from WTELEDSK has been used, because it's GPLed rather than
LGPLed.
2006-11-18 John Elliott
* libdsk-1.1.12 released.
2006-08-02 John Elliott
* cpcemu driver: Bug fix when a sector is not found and it has
to start searching again at the beginning of the track.
2006-07-23 John Elliott
* libdsk-1.1.11 released.
2006-07-02 Ramlaid <www.ramlaid.com>
* cpcemu driver: Modified so that the dsk_trkids() function more
accurately reflects the result from a real disk. Also exposed the
ST0-ST3 registers.
* SQ compression: Doesn't leak file handles if file not compressed.
* NTWDM driver: Uses the passed sector size in dsk_xread / dsk_xwrite
rather than the sector size in the geometry structure.
2006-04-18 John Elliott
* libdsk-1.1.10 released.
2006-04-11 John Elliott
* Extended the Apricot -> PCDOS boot sector conversion code to save
a copy of the original boot sector.
* Created a reverse conversion, PCDOS -> Apricot
* dsktrans: The -apricot option now converts *to* Apricot format,
not *from*. A -pcdos option has been added to convert from Apricot
to PCDOS format.
* A new utility, apriboot, just rewrites the boot sector in place.
2006-04-07 John Elliott
* Made a start on a driver for Apricot MS-DOS.
2006-04-01 John Elliott
* Corrected a problem in the Linux floppy driver that caused 'no data'
errors reading 70-track Apricot discs if the geometry was probed
automatically.
2006-01-21 John Elliott
* libdsk-1.1.9 released.
2006-01-18 John Elliott
* Expanded dskutil with the ability to read and write data.
2005-12-26 John Elliott
* Bugfix: The rcpmfs driver was conflating User 1 and User 0.
2005-12-17 John Elliott
* libdsk-1.1.8 released.
* Added the myz80 geometry as one of the standard geometries,
so that rcpmfs can present drives in the myz80 format.
2005-12-07 John Elliott
* Updated the ApriDisk driver to support an extra block type, which
I hypothesize to be the name of the utility that created the disk
image.
2005-12-05 John Elliott
* Modified the rcpmfs driver to accept SysTracks=0 as a valid
parameter, rather than ignoring it silently.
2005-11-18 John Elliott
* libdsk-1.1.7 released.
2005-11-13 John Elliott
* Added support for reading DSK files created with Simon Owen's
'weak/random data' extension.
* Created dskutil, a simple interactive program allowing arbitrary
sectors to be read. Used to test the weak/random data extension
above.
* Added code to rcpmfs to deal with file truncation.
2005-09-03 John Elliott
* libdsk-1.1.6 released.
* Bug fix: Don't leak file handles in drvcpcem.c.
2005-07-21 John Elliott
* Fixed the '-logical' option in dsktrans so it doesn't fall over
with "bad parameter" errors.
* libdskrc parser now understands 'sides' and 'sidedness' for
the how-to-treat-sidedness parameter.
2005-07-03 John Elliott
* libdsk-1.1.5 released.
2005-06-28 Daniel Black
* Corrected an install bug in Makefile.am
2005-06-14 John Elliott
* Added guard code against a buffer overrun in the DSK driver
(if an attempt is made to format a track with more than 29 sectors)
* Serial remote drivers and standalone serslave written for Linux,
Win32, DOS16, DOS32 (DOS32 untested).
2005-06-14 John Elliott
* Corrected a bug in the Linux and NTWDM drivers - dsk_xread was
failing when the sector size passed in did not match the sector
size in the geometry structure.
* Added dskdump and dskscan to the list of utilities that get
installed.
* dskid(1) allows multiple arguments.
2005-05-10 John Elliott
* Started expanding the internal 'RPC' system to support operation
over serial lines.
2005-03-14 John Elliott
* libdsk-1.1.4 released.
* Added dsk_{p,l}trkids() and dsk_rtread() functions.
* Added COM bindings (Windows version).
2005-02-28 Simon Owen
* Added ntwdm driver.
2005-02-19 Philip Kendall
* Added dsk_dirty() function.
2005-01-26 John Elliott
* libdsk-1.1.3 released.
2005-01-25 John Elliott
* Merged CopyQM format documentation from Per Ola Ingvarsson.
2005-01-21 John Elliott
* dsk_getgeom refactored so that drivers can call the default
guesser and then override individual fields.
* dsk_getgeom also supports detection of BBC Master 512 DOS Plus
format, which is like acorn800 but has 1-based sector numbers.
* CPCEMU read and write now use the passed sector size, not the
size in the geometry structure.
* Merged a read-only CopyQM driver from Per Ola Ingvarsson.
2005-01-18 John Elliott
* Updated ApriDisk driver and apridisk.html with the official
ApriDisk format definitions.
* Continued knocking rcpmfs into shape.
* Added -apricot, -noformat, -first and -last options to dsktrans.
Fixed the -retry option in dsktrans so the default is 1 and not
MAXINT.
2005-01-16 John Elliott
* Updated dg_aprigeom() to use sector size in the Apricot
superblock.
2005-01-03 John Elliott
* LibDsk now loads format definitions from a libdskrc file, allowing
user-defined formats.
* Created an experimental rcpmfs driver which presents a filesystem
directory as a CP/M disk image.
2004-03-27 John Elliott
* v1.1.2 release.
2003-01-11 John Elliott
* Added support for density and recording mode to the DSK and
extended DSK file formats. See appendix C of the documentation
for the details of this.
2003-08-13 John Elliott
* v1.1.1 release.
2003-08-13 John Elliott
* Added dsk_set_retry() and dsk_get_retry() so that LibDsk can
automatically retry reads/writes.
* Added double-stepping support to the Linux floppy driver, thus
allowing 360k floppies to be imaged in 1.2Mb drives.
2003-02-13 John Elliott
* Added a driver for the 'apridisk' disc image format.
* Added support for comments in disc images.
* Added functions for LibDsk to display messages during lengthy
operations.
2003-01-13 John Elliott
* v1.1.0 release.
* Added a mini-RPC system to allow 32-bit Windows applications to use
the more capable 16-bit floppy API.
* The 16-bit DLL is now called LIBDSK16.DLL, so it can be installed in
the same directory as the 32-bit DLL.
* Added a driver for the 'nanowasp' disc image format.
* Removed constraints on the parameter order of the example utilities.
2002-12-16 John Elliott
* v1.0.0 release.
* Minor portability fixes.
* DOS16 and Win16 drivers retry three times; this avoids "Disc changed"
errors on drives that are slow to spin up.
2002-12-01 John Elliott
* v0.9.9 release.
* Projects provided to build LibDsk under 16-bit Windows and DOS;
bug fixes in the .DSK driver to work correctly on a 16-bit compiler
(CFI won't work on 16-bit DOS, except for very small images).
* Drivers added for the Win16, DOS16 and DOS32 architectures. There
may be a case for combining the source files for Win16 and DOS16 as
they are quite similar.
* Previous MYZ80 bugfix was faulty. Corrected.
2002-11-18 John Elliott
* v0.9.5 release.
* MicroDesign serial numbers can be read or altered by md3serial
* Bug fix in the posix driver; when sectors are written beyond the
end of the file, the gap is filled with 0xE5 rather than leaving the
OS to decide what goes there.
* Similar bug fix in the myz80 driver.
2002-04-27 John Elliott
* v0.9.1 release.
* Squeeze compression rewritten from scratch to avoid a possible
licence conflict.
2002-04-10 John Elliott
* v0.9.0 release.
* IMPORTANT CHANGES: This release breaks backward compatibility in a
number of ways. Most importantly, you must replace "DSK_DRIVER *"
with "DSK_PDRIVER " throughout your programs.
* Support for reading/writing deleted data (DSK and Linux floppy
only; other formats do not support marking data as deleted).
* DSK files in the extended CPCEMU format now have their own file
type - "edsk". This means that extended DSK files can be created
using LibDsk.
* Bug fixes in the extended DSK format handler (Thierry Jouin).
* Transparent compression layer added, supporting Squeeze, GZip
and BZip2 (read only).
* Special-case DQK driver removed; the standard CPCEMU driver +
the compression layer can now handle this case.
* BBC Micro DFS formats added to the list of built-in formats, and
to the geometry probe.
* Bugfix in the Linux floppy driver so that discs with FM encoding
can be read (requires a suitable floppy controller and drive).
2002-04-06 John Elliott
* v0.8.2 release.
* New driver added: .DQK (.DSK compressed using Squeeze compression).
* XCF2 200k format added to the list of built-in formats.
* Darren Salt's manual pages added to the distribution.
2002-02-25 John Elliott
* v0.8.0 release.
* Support added for Java Native Interface bindings (requires JDK
v1.1 or later). Use ./configure --with-jni to build them.
* Java versions of dskid, dskform and dsktrans added.
2002-02-07 John Elliott
* v0.7.0 release.
* Support added for .CFI format (a strange format used by Cliff
Lawson to distribute Amstrad PC boot floppies).
* Bug fixes in the example utilities (Darren Salt).
* dsktrans includes a -format option to use a built-in geometry
rather than trying to probe it from the disc.
* PCW 800k format added to list of builtin formats.
2002-01-15 John Elliott
* v0.6.0 release.
* Acorn ADFS formats added to the list of formats, and to the
geometry probe. These don't work on Windows because of the limitations
of the underlying floppy driver.
* dsk_xread() and dsk_xwrite() altered so that only part of a sector
can be read or written.
* Make libdsk compile in Microsoft Visual C++ (Kevin Thacker)
* dskform supports all built-in disc geometries.
* dg_stdformat() can be used to enumerate the built-in geometries.
* dsktrans includes a "-logical" option to rearrange the tracks of
a disc, so that they come out in logical order in a "raw" file. This
option is only effective for ADFS and 144FEAT formats.
