This is pretty much a relaunch of the project,
the internet site and the accompanying documentation.
There are too much changes for a detailed report.
The most prominent feature of this version is that
the multithreaded RS03 codec reached production
quality, and all required features have been implemented.
A few things will be added with the next releases:
- adaptive reading is currently disabled as it does
not support RS03 yet and would crash or misbehave
on RS03 error correction data
- a heuristic for an exhaustive re-discovery of RS03
structures in a badly damaged medium is missing in
the decoder
But these things should not keep you from using RS03,
as the encoder is complete and future decoder enhancements
do not affect already created RS03 data.

changes:
- fixed crash in scsi layer for FreeBSD
- fixed double free when reading mode page 1 fails
- fixed DMA misalignment when reading mode page 1
- changed #includes for glibc for compatibility with 2.32
- dropped Darwin/Mac OS X support
- removed dependency on installed md5sum command
- changed libpng test in configure to utilize pkg-config
- fixed some minor flaws for NetBSD

- Blu-ray support
- added CD raw reading and majority algorithm
- C2 scanning support for CD media
- changed treatment of CRC failures: old behaviour was to
store a defective sector marker; now the actual sector
contents are written to the image file.
- Using the CDROM_SEND_PACKET ioctl() will hang parallel
SCSI adapters. Added tests to determine the SCSI bus type,
and switch to the SG_IO ioctl() when in doubt. [Linux]
- fixed and documented -n command line options for RS02.

Maintainer update by Sergey Svishchev (small changes by Klaus Heinz)
Pkgsrc changes:
- Required version of GTK2 is now 2.6.0 and up.
- Many pkgsrc patches related to NetBSD support (scsi-netbsd.c, patch-ab,
patch-ac, patch-ae and part of patch-ad) were committed to the stable
branch of dvdisaster (0.70.x). The rest (except for patch-ah) was
integrated into the unstable branch (0.71.x).
Changes since version 0.70.4:
=============================
NOTE to downstream maintainers:
- Keep up the good work! Thanks :-)
- GTK+ dependency has been bumped up to >= 2.6.0 (was formerly 2.0)
0.70 (pl6) 04-03-2008
- rolled back the Windows filename encoding fixes;
they caused large file support to be broken
Thanks to Markus G. for bringing this to my attention!
0.70 (pl5) 24-02-2008 various backports from 0.71.24:
- enlarged scsi timeout for Linux as newer Kernels seem
to freeze on timeout
- Windows filename encoding fixes

The package was created by Sergey Svishchev, some changes done by me.
CD and DVD media keep their data only for a finite time (typically for
many years). After that time, data loss develops slowly with read errors
growing from the outer media region towards the inside.
Dvdisaster stores data on CD/DVD in a way that it is fully recoverable
even after some read errors have developed. This enables you to rescue
the complete data to a new medium.
Data loss is prevented by using error correcting codes. Error correction
data is either added to the medium or kept in separate error correction
files. dvdisaster works at the image level so that the recovery does not
depend on the file system of the medium. The maximum error correction
capacity is user-selectable.
