version 2.1.0
=============
2019-04-17 Holy Wednesday

Most (all?) of the improvements and bug fixes are thanks to Thomas Schmitt and Edd Barrett. This release introduces an OpenBSD driver, courtesy of Edd Barrett, based on the NetBSD driver.

- NetBSD driver fixes. Switch from MSF addressing to LBA addressing in driver. (Edd Barrett and Jasper Lievisse Adriaanse)
- Fix handling in drivers,libcdio-paranoia and `cd-info` when starting track number is greater than 1. (Edd Barrett and Thomas Schmitt)
- More tolerant of non-compliant ISOs such as openSUSE Leap 15.0.
- `cdda-player` fixes, such as adding a missing `-d` in cdda-player help (Thomas Schmitt and Edd Barrett)
- `cdtext_list_languages_v2()` to be preferred over now deprecated `cdtext_list_languages()`. New API call `cdtext_set_language_index()`. (Thomas Schmitt)
- Add `read-disc-struct` example program to show how to use a MMC `DVD_READ_DISC_STRUCTURE`. (Thomas Schmitt)
- Various errors in driver reading turned into warnings. (Edd Barrett and Thomas Schmitt)
- Some code cleanups and documentation improvements.
- Bugs:
 * [Bug 53170: I/O leak when we can't read ISO file ](https://savannah.gnu.org/bugs/index.php?53170)
 * [Bug 53928: Cdtext not displayed in case of `CDTEXT_LANGUAGE_UNKNOWN`](https://savannah.gnu.org/bugs/index.php?3929)
 * [Bug 53929: cd-text with invalid characters failing to convert to utf8](https://savannah.gnu.org/bugs/index.php?3928)

version 2.0.0
=============
2017-12-31

This release bumps library version numbers and bumps the major release number. We should have gone from 1.0.0 to 2.0.0 in the last release
since there is an API incompatibility.

In addition...

- Add NetBSD drive detection; correct drive detection in `cd-info.c`
  Patches from Onno van der Linden
- Fix some MinGW and Windows portability issues
- Remove some memory leaks in some tests
- Lint (a little) with clang static analyzer

There are some programs and bindings that will need to be updated
if you want to use them with this library. Specifically:

- `Device::Cdio` (2.0.0 or greater)
- `vcdimager` (2.0.0 or greater)
- `pycdio` (2.0.0 or greater)
- `rbcdio` (2.0.0 or greater)

version 1.1.0
=============
2017-12-10  Dr. Gecko

Caveats:
`pycdio` and `Device::Perl` will be broken but that'll be fixed later

- Remove many remaining memory leaks, invalid reads, writes (as per valgrind) in library, test and demo code
- Types `CdioISO9660DirList_t` and `CdioISO9660FileList_t`, `iso9660_{dir,file}list_{new,free}` have been added.
- `cdio_list_free()` now takes an additional parameter: a function to
  free list items. This is not compatible with 1.0.0.

More work is needed on MacOS and other OS's where I don't have
`valgrind` accessible.

AIX is left untouched - that is probably heading for removal in the future.

  * OpenBSD tested (no native CD driver though)

- Doxygen formatting improvements.

  * fixed bincue driver caused core dump on set_speed and
    set_blocksize; it also called the wrong routine (from NRG) to get a
    list of cd-images.
  * read.h didn't make sure off_t was defined.
  * fixed bug in is_device() when driver_id = DRIVER_UNKNOWN or DRIVER_DEVICE.
  * OSX was freeing too much in listing drives.

    various timezone offsets, daylight savings time, and tm capabilities

- More accurate library dependency tracking in linking and `pkg-config`
- Miscellaneous minor bug fixes.
- `cdio/cdda.h` headers no longer depends on cdio/paranoia.h but vice versa
