Changelog {#changelog}
=========
For fully detailed change log, please see the source repository directly. This
is just a high-level summary.
### libopenmpt 0.4.4 (2019-04-07)
* [**Bug**] Channel VU meters were swapped.
* Startrekker: Clamp speed to 31 ticks per row.
* MTM: Ignore unused Exy commands on import. Command E5x (Set Finetune) is now
applied correctly.
* MOD: Sample swapping was always enabled since it has been separated from the
ProTracker 1/2 compatibility flag. Now it is always enabled for Amiga-style
modules and otherwise the old heuristic is used again.
* stb_vorbis: Update to v1.16 (2019-03-05).
### libopenmpt 0.4.3 (2019-02-11)
* [**Sec**] Possible crash due to null-pointer access when doing a portamento
from an OPL instrument to an empty instrument note map slot (r11348).
* [**Bug**] libopenmpt did not compile on Apple platforms in C++17 mode.
* IT: Various fixes for note-off + instrument number in Old Effects mode.
* MO3: Import IT row highlights as written by MO3 2.4.1.2 or newer. Required
for modules using modern tempo mode.
* miniz: Update to v2.0.8 (2018-09-19).
* stb_vorbis: Update to v1.15 (2019-02-07).
### libopenmpt 0.4.2 (2019-01-22)
* [**Sec**] DSM: Assertion failure during file parsing with debug STLs
(r11209).
* [**Sec**] J2B: Assertion failure during file parsing with debug STLs
(r11216).
* S3M: Allow volume change of OPL instruments after Note Cut.
### libopenmpt 0.4.1 (2019-01-06)
* [**Bug**] Binaries compiled for winold (Windows XP, Vista, 7, for CPUs
without SSE2 support) did not actually work on CPUs without SSE2 support.
* [**Bug**] libmodplug: Public symbols of the C++ API had `visibility=hidden`
set on non-MSVC systems, which made them not publicly accessible.
* [**Bug**] Project files for Windows 10 desktop builds on ARM and ARM64
(`build/vs2017win10`) were missing from Windows source package.
* [**Bug**] MSVC project files in Windows source package lacked additional
files required to build DLLs.
* MO3: Apply playback changes based on "ModPlug-made" header flag.
* minimp3: Update to commit e9df0760e94044caded36a55d70ab4152134adc5
(2018-12-23).
### libopenmpt 0.4.0 (2018-12-23)
* [**New**] libopenmpt now includes emulation of the OPL chip and thus plays
OPL instruments in S3M, C67 and MPTM files. OPL chip emulation volume can be
changed with the new ctl `render.opl.volume_factor`.
* [**New**] libopenmpt now supports CDFM / Composer 670 module files.
* [**New**] Autotools `configure` and plain `Makefile` now honor the variable
`CXXSTDLIB_PCLIBSPRIVATE` which serves the sole purpose of listing the
standard library (or libraries) required for static linking. The contents of
this variable will be put in `libopenmpt.pc` `Libs.private` and used for
nothing else. See \ref libopenmpt_c_staticlinking .
* [**New**] foo_openmpt: foo_openmpt now also works on Windows XP.
* [**New**] libopenmpt Emscripten builds now ship with MP3 support by
default, based on minimp3 by Lion (github.com/lieff).
* [**New**] libopenmpt: New ctl `play.at_end` can be used to change what
happens when the song end is reached:
* "fadeout": Fades the module out for a short while. Subsequent reads
after the fadeout will return 0 rendered frames. This is the default and
identical to the behaviour in previous libopenmpt versions.
* "continue": Returns 0 rendered frames when the song end is reached.
Subsequent reads will continue playing from the song start or loop
start. This can be used for custom loop logic, such as loop
auto-detection and longer fadeouts.
* "stop": Returns 0 rendered frames when the song end is reached.
Subsequent reads will return 0 rendered frames.
* [**New**] Add new metadata fields `"originaltype"` and `"originaltype_long"`
which allow more clearly reflecting what is going on with converted formats
like MO3 and GDM.
* [**New**] `Makefile` `CONFIG=emscripten` now can generate WebAssembly via
the additional option `EMSCRIPTEN_TARGET=wasm`.
* [**New**] Compiling for DOS is now experimentally supported via DJGPP GCC
7.2 or later.
* [**Change**] minimp3: Instead of the LGPL-2.1-licensed minimp3 by KeyJ,
libopenmpt now uses the CC0-1.0-licensed minimp3 by Lion (github.com/lieff)
as a fallback if libmpg123 is unavailable. The `USE_MINIMP3` `Makefile`
option is gone and minimp3 will be used automatically in the `Makefile`
build system if libmpg123 is not available.
* [**Change**] openmpt123: openmpt123 now rejects `--output-type` in `--ui`
and `--batch` modes and also rejects `--output` in `--render` mode. These
combinations of options really made no sense and were rather confusing.
* [**Change**] Android NDK build system now uses libc++ (`c++_shared`) instead
of GNU libstdc++ (`gnustl_shared`), as recommended by Android NDK r16b.
* [**Change**] xmp-openmpt: `openmpt-mpg123.dll` is no longer optional and
must be placed into the same directory as `xmp-openmpt.dll`.
* [**Change**] in_openmpt: `openmpt-mpg123.dll` is no longer optional and must
be placed either into the directory of the player itself or into the same
directory as `in_openmpt.dll`. This is dependent on how the player loads its
plugins. For WinAMP 5, `openmpt-mpg123.dll` needs to be in the directory
which contains `winamp.exe`. `in_openmpt.dll` needs to be in the `Plugins`
directory.
* [**Change**] foo_openmpt: foo_openmpt is now packaged as a fb2k-component
package for easier installation.
* [**Change**] When building libopenmpt with MinGW-w64, it is now recommended
to use the posix thread model (as opposed to the win32 threading model),
because the former does support std::mutex while the latter does not. When
building with win32 threading model with the Autotools build system, it is
recommended to provide the `mingw-std-threads` package. Building libopenmpt
with MinGW-w64 without any `std::thread`/`std::mutex` support is deprecated
and support for such configurations will be removed in libopenmpt 0.5.
* [**Change**] `Makefile` `CONFIG=emscripten` now has 4 `EMSCRIPTEN_TARGET=`
settings: `wasm` generates WebAssembly, `asmjs128m` generates asm.js with a
fixed size 128MB heap, `asmjs` generates asm.js with a fixed default size
heap (as of Emscripten 1.38.11, this amounts to 16MB), `js` generates
JavaScript with dynamic heap growth and with compatibility for older VMs.
* [**Change**] libmodplug: Update public headers to libmodplug 0.8.8.5. This
adds support for kind-of automatic MODPLUG_EXPORT decoration on Windows.
* [**Regression**] Support for Clang 3.4, 3.5 has been removed.
* [**Regression**] Building with Android NDK older than NDK r16b is not
supported any more.
* [**Regression**] Support for Emscripten versions older than 1.38.5 has been
removed.
* [**Regression**] Support for libmpg123 older than 1.14.0 has been removed.
* [**Regression**] Using MediaFoundation to decode MP3 samples is no longer
supported. Use libmpg123 or minimp3 instead.
* [**Regression**] libmodplug: Support for emulating libmodplug 0.8.7 API/ABI
has been removed.
* [**Bug**] xmp-openmpt: Sample rate and number of output channels were not
applied correctly when using per-file settings.
* [**Bug**] Internal mixer state was not initialized properly when initially
rendering in 44100kHz stereo format.
* [**Bug**] openmpt123: Prevent libsdl2 and libsdl from being enabled at the
same time because they conflict with each other.
* [**Bug**] libmodplug: Setting `SNDMIX_NORESAMPLING` in the C++ API always
resulted in linear interpolation instead of nearest neighbour
* IT: In Compatible Gxx mode, allow sample changes next to a tone portamento
effect if a previous sample has already stopped playing.
* IT: Fix broken volume envelopes with negative values as found in breakdwn.it
by Elysis.
* MOD: Slides and delayed notes are executed on every repetition of a row with
row delay (fixes "ode to protracker").
* XM: If the sustain point of the panning envelope is reached before key-off,
it is never released.
* XM: Do not default recall volume / panning for delayed instrument-less notes
* XM :E60 loop bug was not considered in song length calucation.
* S3M: Notes without instrument number use previous note's sample offset.
* Tighten M15 and MOD file rejection heuristics.
* J2B: Ignore frequency limits from file header. Fixes Medivo.j2b, broken
since libopenmpt-0.2.6401-beta17.
* STM: More accurate tempo calculation.
* STM: Better support for early format revisions (no such files have been
found in the wild, though).
* STM: Last character of sample name was missing.
* SFX: Work around bad conversions of the "Operation Stealth" soundtrack by
turning pattern breaks into note stops.
* IMF: Filter cutoff was upside down and the cutoff range was too small.
* ParamEq plugin center frequency was not limited correctly.
* Keep track of active SFx macro during seeking.
* The "note cut" duplicate note action did not volume-ramp the previously
playing sample.
* A song starting with non-existing patterns could not be played.
* DSM: Support restart position and 16-bit samples.
* DTM: Import global volume.
* MOD: Support notes in octave 2, like in FastTracker 2 (fixes DOPE.MOD).
* Do not apply Amiga playback heuristics to MOD files that have clearly been
written with a PC tracker.
* MPTM: More logical release node behaviour.
* Subsong search is now less thorough. It could previously find many subsongs
that are technically correct (unplayed rows at the beginning of patterns
that have been jumped over due to pattern breaks), but so far no real-world
module that would require such a thorough subsong detection was found. The
old mechanism caused way more false positives than intended with real-world
modules, though.
* Restrict the unpacked size of compressed DMF, IT, MDL and MO3 samples to
avoid huge allocations with malformed small files.
### libopenmpt 0.3 (2017-09-27)
* [**New**] New error handling functionality in the C API, which in particular
allows distinguishing potentially transient out-of-memory errors from parse
errors during module loading.
* [**New**] New API `openmpt::module::get_selected_subsong()` (C++) and
`openmpt_module_get_selected_subsong()` (C).
* [**New**] Faster file header probing API `openmpt::probe_file_header()` and
`openmpt::probe_file_header_get_recommended_size` (C++), and
`openmpt_probe_file_header()`,
`openmpt_probe_file_header_without_filesize()`,
`openmpt_probe_file_header_from_stream()` and
`openmpt_probe_file_header_get_recommended_size()` (C).
* [**New**] New API `openmpt::could_open_probability()` (C++) and
`openmpt_could_open_probability()` (C). This fixes a spelling error in the
old 0.2 API.
* [**New**] openmpt123: openmpt123 can now open M3U, M3U8, M3UEXT, M3U8EXT and
PLSv2 playlists via the `--playlist` option.
* [**New**] openmpt123: openmpt123 now supports very fast file header probing
via the `--probe` option.
* [**New**] Libopenmpt now supports building for Windows 10 Universal (Windows
Store 8.2) APIs with MSVC, and also for the older Windows Runtime APIs with
MinGW-w64.
* [**New**] New API header `libopenmpt_ext.h` which implements the libopenmpt
extension APIs also for the C interface.
* [**New**] The Reverb effect (S99 in S3M/IT/MPTM, and X99 in XM) is now
implemented in libopenmpt.
* [**New**] For Amiga modules, a new resampler based on the Amiga's sound
characteristics has been added. It can be activated by passing the
`render.resampler.emulate_amiga` ctl with a value of `1`. Non-Amiga modules
are not affected by this, and setting the ctl overrides the resampler choice
specified by `OPENMPT_MODULE_RENDER_INTERPOLATIONFILTER_LENGTH` or
`openmpt::module::RENDER_INTERPOLATIONFILTER_LENGTH`. Support for the MOD
command E0x (Set LED Filter) is also available when the Amiga resampler is
enabled.
* [**Change**] libopenmpt versioning changed and follows the more conventional
major.minor.patch as well as the recommendations of the
[SemVer](http://semver.org/) scheme now. In addition to the SemVer
requirements, pre-1.0.0 versions will also honor API and ABI stability in
libopenmpt (i.e. libopenmpt ignores SemVer Clause 4).
* [**Change**] The output directories of the MSVC build system were changed to
`bin/vs2015-shared/x86-64-win7/` (and similar) layout which allows building
in the same tree with different compiler versions without overwriting other
outputs.
* [**Change**] The emscripten build now exports libopenmpt as 'libopenmpt'
instead of the default 'Module'.
* [**Change**] Android: The build system changed. The various Android.mk files
have been merged into a single one which can be controlled using command
line options.
* [**Change**] The `Makefile` build system now passes `std=c++11` to the
compiler by default. Older compilers may still work if you pass
`STDCXX=c++0x` to the `make` invocation.
* [**Change**] The `Makefile` option `ANCIENT=1` is gone.
* [**Change**] The optional dependencies on `libltdl` or `libdl` are gone.
They are no longer needed for any functionality.
* [**Regression**] Compiling client code using the C++ API now requires a
compiler running in C++11 mode.
* [**Regression**] Support for GCC 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7 has been
removed.
* [**Regression**] Support for Clang 3.0, 3.1, 3.2, 3.3 has been removed.
* [**Regression**] Support for Emscripten versions older than 1.31.0 has been
removed.
* [**Regression**] Support for Android NDK versions older than 11 has been
removed.
* [**Regression**] Visual Studio 2008, 2010, 2012, 2013 support has been
removed.
* [**Regression**] Dynamic run-time loading of libmpg123 is no longer
supported. Libmpg123 must be linked at link-time now.
* [**Regression**] xmp-openmpt: xmp-openmpt now requires XMPlay 3.8 or later
and compiling xmp-openmpt requires an appropriate XMPlay SDK with
`XMPIN_FACE` >= `4`.
* [**Regression**] Support for libmpg123 older than 1.13.0 has been removed.
* [**Regression**] Un4seen unmo3 support has been removed.
* [**Bug**] C++ API: `openmpt::exception` did not define copy and move
constructors or copy and move assignment operators in libopenmpt 0.2. The
compiler-generated ones were not adequate though. libopenmpt 0.3 adds the
appropriate special member functions. This adds the respective symbol names
to the exported ABI, which, depending on the compiler, might or might not
have been there in libopenmpt 0.2. The possibly resulting possible ODR
violation only affects cases that did crash in the libopenmpt 0.2 API anyway
due to memory double-free, and does not cause any further problems in
practice for all known platforms and compilers.
* [**Bug**] The C API could crash instead of failing gracefully in
out-of-memory situations.
* [**Bug**] The test suite could fail on MacOSX or FreeBSD in non-fatal ways
when no locale was active.
* [**Bug**] `libopenmpt_stream_callbacks_fd.h` and
`libopenmpt_stream_callbacks_file.h` were missing in Windows development
packages.
* [**Bug**] libopenmpt on Windows did not properly guard against current
working directory DLL injection attacks.
* [**Bug**] localtime() was used to determine the version of Schism Tracker
used to save IT and S3M files. This function is not guaranteed to be
thread-safe by the standard and is now no longer used.
* [**Bug**] Possible crashes with malformed IT, ITP, AMS, MDL, MED, MPTM, PSM
and Startrekker files.
* [**Bug**] Possible hangs with malformed DBM, MPTM and PSM files.
* [**Bug**] Possible hangs with malformed files containing cyclic plugin
routings.
* [**Bug**] Excessive loading times with malformed ITP / truncated AMS files.
* [**Bug**] Plugins did not work correctly when changing the sample rate
between two render calls.
* [**Bug**] Possible NULL-pointer dereference read during obscure
out-of-memory situations while handling exceptions in the C API.
* [**Bug**] libmodplug: `libmodplug.pc` was wrong.
* [**Bug**] Cross-compiling libopenmpt with autotools for Windows now properly
sets `-municode` and `-mconsole` as well as all required Windows system
libraries.
* [**Bug**] foo_openmpt: Interpolation filter and volume ramping settings were
confused in previous versions. This version resets both to the defaults.
* [**Bug**] libmodplug: The CSoundFile::Read function in the emulated
libmodplug C++ API returned the wrong value, causing qmmp (and possibly
other software) to crash.
* Support for SoundTracker Pro II (STP) and Digital Tracker (DTM) modules.
* Increased accuracy of the sample position and sample rate to drift less when
playing very long samples.
* Various playback improvements for IT and XM files.
* Channel frequency could wrap around after some excessive portamento / down
in some formats since libopenmpt 0.2-beta17.
* Playback improvements for S3M files made with Impulse Tracker and
Schism Tracker.
* ParamEq plugin emulation didn't do anything at full gain (+15dB).
* All standard DMO effects are now also emulated on non-Windows and non-MSVC
systems.
* Added `libopenmpt_stream_callbacks_buffer.h` which adds
`openmpt_stream_callbacks` support for in-memory buffers, possibly even only
using a truncated prefix view into a bigger file which is useful for
probing.
* Avoid enabling some ProTracker-specific quirks for MOD files most likely
created with ScreamTracker 3.
* Tremolo effect only had half the intended strength in MOD files.
* Pattern loops ending on the last row a pattern were not executed correctly
in S3M files.
* Work-around for reading MIDI macros and plugin settings in some malformed IT
files written by old UNMO3 versions.
* Improve tracker detection in IT format.
* Playback fixes for 8-channel MED files
* Do not set note volume to 0 on out-of-range offset in XM files.
* Better import of some slide commands in SFX files.
* Sample 15 in "Crew Generation" by Necros requires short loops at the
beginning of the sample to not be ignored. Since we need to ignore them in
some (non-ProTracker) modules, we heuristically disable the old loop
sanitization behaviour based on the module channel count.
* Both normal and percentage offset in PLM files were handled as percentage
offset.
* MT2 files with instruments that had both sample and plugin assignments were
not read correctly.
* Some valid FAR files were rejected erroneously.
* Support for VBlank timing flag and comment field in PT36 files.
* Improved accuracy of vibrato command in DIGI / DBM files.
* STM: Add support for "WUZAMOD!" magic bytes and allow some slightly
malformed STM files to load which were previously rejected.
* Detect whether "hidden" patterns in the order list of SoundTracker modules
should be taken into account or not.
* Tighten heuristics for rejecting invalid 669, M15, MOD and ICE files and
loosen them in other places to allow some valid MOD files to load.
* Improvements to seeking: Channel panning was not always updated from
instruments / samples when seeking, and out-of-range global volume was not
applied correctly in some formats.
* seek.sync_samples=1 did not apply PTM reverse offset effect and the volume
slide part of combined volume slide + vibrato commands.
* If the order list was longer than 256 items and there was a pattern break
effect without a position jump on the last pattern of the sequence, it did
not jump to the correct restart order.
* `Makefile` has now explicit support for FreeBSD with no special option or
configuration required.
* openmpt123: Improved section layout in man page.
* libmodplug: Added all missing C++ API symbols that are accessible via the
public libmodplug header file.
* Autotools build system now has options `--disable-openmpt123`,
`--disable-tests` and `--disable-examples` which may be desireable when
cross-compiling.
* Windows binary packages now ship with libmpg123 included.
### libopenmpt 0.2-beta20 (2016-08-07)
* [**Bug**] PSM loader was broken on big-endian platforms since forever.
* [**Bug**] `load.skip_samples` ctl did not work for PSM16 modules.
* There is a new `subsong` ctl, which can return the currently selected
subsong.
* More accurate ProTracker arpeggio wrap-around emulation.
* More accurate sample tuning in PSM16 files.
* Samples in DSM files were sometimes detuned and some pattern commands were
not imported correctly.
* More accurate import of MDL 7-bit panning command.
* Only import pattern commands supported by the UltraTracker version that was
used to save ULT files. Add support for command 5-C (end loop).
* DMF sample loop lengths were off by one.
* Unis 669 pan slide effect was too deep.
* Several valid (but slightly corrupted possibly due to disk failures or data
transfer errors) SoundTracker files were no longer loading since libopenmpt
0.2-beta18.
### libopenmpt 0.2-beta19 (2016-07-23)
* [**Change**] libopenmpt now uses C++14 `[[deprecated]]` attribute instead
of compiler-specific solutions when appropriate.
* [**Change**] libopenmpt C++ header now uses C++11 `noexcept` instead of
C++98 `throw()` exception specification when supported. `throw()` is
deprecated since C++11. This does not change API or ABI as they are
equivalent. Use `LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT` to override the
default.
* [**Change**] The preprocessor macro `LIBOPENMPT_ANCIENT_COMPILER_STDINT` is
gone. Please use `LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT instead`.
Additionally, the typedefs moved from illegal namespace ::std into somewhat
less dangerous namespace ::openmpt::std. You can test
`#ifdef LIBOPENMPT_QUIRK_NO_CSTDINT` client-side to check whether
`libopenmpt.hpp` used the non-standard types. (Note: Of all supported
compilers, this change only affects the 3 compilers with only limited
support: MSVC 2008, GCC 4.1, GCC 4.2.)
* [**Bug**] xmp-openmpt: Crash when viewing sample texts.
* The public libopenmpt C++ header has auto-detection logic for the used C++
standard now. In case your client code compiler misreports the standard
version or you want to override it for other reasons,
`#define LIBOPENMPT_ASSUME_CPLUSPLUS` to the value of the standard version
you desire to be used. There is also a macro for each individual aspect,
like `LIBOPENMPT_ASSUME_CPLUSPLUS_CSTDINT`,
`LIBOPENMPT_ASSUME_CPLUSPLUS_DEPRECATED`,
`LIBOPENMPT_ASSUME_CPLUSPLUS_NOEXCEPT` which take precedence over the
general macro.
* Portamento with sample swap behaviour was wrong for ProTracker MODs.
* Rewritten loader and various playback fixes for MDL files.
* libopenmpt 0.2-beta18 broke import of many pattern commands in DBM, DMF and
ULT files.
* ADPCM samples in MOD files were broken since libopenmpt 0.2-beta17.
### libopenmpt 0.2-beta18 (2016-07-11)
* [**Change**] openmpt123: Add PulseAudio output support. Autotools and
`Makefile` build systems now depend on `libpulse` and `libpulse-simple` by
default. Disable with `--without-pulseaudio` or `NO_PULSEAUDIO=1`
respectively. When enabled, PulseAudio will be the default output driver,
* [**Change**] xmp-openmpt: Settings are now stored in xmplay.ini like with
every other plugin.
* [**Regression**] openmpt123: Support for FLAC < 1.3.0 has been removed. FLAC
before 1.3.0 is broken beyond repair as it provides `assert.h` in the
include path.
* [**Bug**] Generated pkg-config file libopenmpt.pc by both `Makefile` and
Autotools build systems was totally broken.
* [**Bug**] libopenmpt no longer uses the non-thread-safe global std::rand()
function.
* [**Bug**] Sample loops in GDM modules did not work when using Emscripten.
* [**Bug**] XM and MO3 loaders could crash due to unaligned memory accesses.
* [**Bug**] Fixed incorrect handling of custom MPTM tunings on big endian
platforms.
* [**Bug**] Fixed various problems found with clang 3.8 static analyzer,
address sanitizer and undefined behaviour sanitizer.
* [**Bug**] File header probing functionality was broken for most formats.
* [**Bug**] With non-seekable streams, the entire file was almost always
cached even if it was not of any supported module type.
* Seeking in allsubsongs-mode now works correctly.
* openmpt123: Added subsong support.
* Various playback fixes for 669, IT, MT2 and MTM files.
* Some MOD files with more than 128 patterns (e.g. NIETNU.MOD) were not loaded
correctly.
* A new example `libopenmpt_example_c_probe` has been added which demonstrates
the usage and flexibility of openmpt_could_open_propability() in the C API
under various constraints.
### libopenmpt 0.2-beta17 (2016-05-21)
* [**Change**] The Makefile and Autotools build systems now require to
explicitly specify `NO_LTDL=1` or `--without-ltdl` respectively if no
support for dynamic loading of third party libraries via libtool libltdl is
desired.
* [**Change**] In the Makefile build system option `USE_MO3` and the Autotools
build system option `--enable-mo3` are gone. Dynamic loading of un4seen
unmo3 is now always enabled when dynamic loading is possible and built-in
MO3 support is not possible because either a MP3 or a Vorbis decoder is
missing.
* [**Change**] The MSVC build system changed. The `libopenmptDLL` project is
gone. Use the new `ReleaseShared` configuration of the `libopenmpt` project
instead. libopenmpt now links against zlib by default. A separate project
with smaller footprint linking against miniz is still available as
`libopenmpt-small`.
* [**Change**] The constants used to query library information from
`openmpt_get_string()` and `openmpt::string::get()` (i.e. OPENMPT_STRING_FOO
and openmpt::string::FOO) have been deprecated because having syntactic
constants for theses keys makes extending the API in a backwards and
forwards compatible way harder than it should be. Please just use the string
literals directly.
* [**Change**] Deprecated API identifiers will now cause deprecation warnings
with MSVC, GCC and clang. `#define LIBOPENMPT_NO_DEPRECATE` to disable the
warnings.
* [**Change**] openmpt123: `--[no-]shuffle` option has been renamed to
`--[no-]randomize`. A new `--[no-]shuffle` option has been added which
shuffles randomly through the playlist as opposed to randomizing the
playlist upfront.
* [**Change**] Support for Un4seen unmo3 has generally been deprecated in
favour of the new internal mo3 decoder. Un4seen unmo3 support will be
removed on 2018-01-01.
* [**Bug**] Memory consumption during loading has been reduced by about 1/3 in
case a seekable input stream is provided (either via C API callback open
functions or via C++ API iostream constructors).
* [**Bug**] Some samples in AMS modules were detuned when using Emscripten.
* [**Bug**] Possible crash with excessive portamento down in some formats.
* [**Bug**] Possible crashes with malformed AMF, AMS, DBM, IT, MDL, MED, MPTM,
MT2, PSM and MMCMP-, XPK- and PP20-compressed files.
* [**Bug**] `openmpt::module::format_pattern_row_channel` with `width == 0`
was returning an empty string instead of an string with unconstrained
length.
* Support for ProTracker 3.6 IFF-style modules and SoundFX / MultiMedia Sound
(SFX / MMS) modules.
* libopenmpt now has support for DMO plugins on Windows when built with MSVC.
Additionally, the DMO Compression, Distortion, Echo, Gargle, ParamEQ and
WavesReverb DSPs are emulated on on all other platforms.
* libopenmpt now supports the DigiBooster Echo DSP.
* To avoid any of the aforementioned plugins to be used, the load.skip_plugins
ctl can be passed when loading a module.
* libopenmpt got native MO3 support with MP3 decoding either via libmpg123 or
MediaFoundation (on Windows 7 and up) and Vorbis decoding via libogg,
libvorbis, libvorbisfile or stb_vorbis.
* libopenmpt MSVC builds with Visual Studio 2010 or later on Windows 7 or
later now use an internal MO3 decoder with libogg, libvorbis, libvorbisfile,
and libmpg123 or minimp3 or MediaFoundation suppport by default. Visual
Studio 2008 builds still use unmo3.dll by default but also support the
built-in decoder in which case libmpg123 is required.
* libopenmpt with Makefile or Autotools build system can now also use
glibc/libdl instead of libtool/libltdl for dynamic loading of third-party
libraries. Options `NO_DL=1` and `--without-dl` have been added
respectively.
* The `Makefile` build system got 4 new options NO_MPG123, NO_OGG, NO_VORBIS,
NO_VORBISFILE. The default is to use the new dependencies automatically.
* The `Autotools` build system got 4 new options --without-mpg123,
--without-ogg, --without-vorbis, --without-vorbisfile. The default is to use
the new dependencies automatically.
* Makefile and Android builds got support for using minimp3 instead of
libmpg123. For Android, use `Android-minimp3-stbvorbis.mk`, for Makefile use
`USE_MINIMP3=1`. You have to download
[minimp3](http://keyj.emphy.de/minimp3/) yourself and put its contents into
`include/minimp3/`.
* `"source_url"`, `"source_date"` and `"build_compiler"` keys have been added
to `openmpt_string_get()` and `openmpt::string::get()`.
* openmpt123: Add new `--[no-]restart]` option which restarts the playlist
when finished.
* Improved Ultimate SoundTracker version detection heuristics.
* Playing a sample at a sample rate close to the mix rate could lead to small
clicks when using vibrato.
* More fine-grained internal legacy module compatibility settings to correctly
play back modules made with older versions of OpenMPT and a few other
trackers.
* The tail of compressed MDL samples was slightly off.
* Some probably hex-edited XM files (e.g. cybernostra weekend.xm) were not
loaded correctly.
* Countless other playback fixes for MOD, XM, S3M, IT and MT2 files.
### libopenmpt 0.2-beta16 (2015-11-22)
* [**Change**] The Autotools build system does strict checking of all
dependencies now. Instead of best effort auto-magic detection of all
potentially optional dependencies, the default set of dependencies is now
enforced unless each individual dependency gets explicitely disabled via
`--without-foo` or `--disable-foo` `./configure` switches. Run
`./configure --help` for the full list of options.
* [**Bug**] Some MOD files were erroneously detected as 669 files.
* [**Bug**] Some malformed AMF files could result in very long loading times.
* [**Bug**] Fixed crashes in IMF and MT2 loaders.
* [**Bug**] MTM files generated by UNMO3 were not loaded properly.
* Improved MTM playback.
* `make CONFIG=haiku` for Haiku has been added.
* Language bindings for FreeBASIC have been added (see
`libopenmpt/bindings/`).
### libopenmpt 0.2-beta15 (2015-10-31)
* [**Change**] openmpt123: SDL2 is now supported and preferred to SDL1 if
available with the `Makefile` build system.
* [**Bug**] Emscripten support for older emscripten versions broke in -beta14.
These are now supported again when using `make CONFIG=emscripten-old`.
* [**Bug**] Fixed crashes in MED loader.
* Playback improvements and loader fixes for MOD, MT2 and MED.
### libopenmpt 0.2-beta14 (2015-09-13)
* [**Change**] The C++ API example now uses the PortAudio C++ bindings
instead of the C API.
* [**Change**] Default compiler options for Emscripten have been changed to
more closely match the Emscripten recommendations.
* [**Bug**] Client code compilation with C89 compilers was broken in beta13.
* [**Bug**] Test suite failed on certain Emscripten/node.js combinations.
* [**Bug**] Fixed various crashes or hangs in DMF, OKT, PLM, IT and MPTM
loaders.
* Implemented error handling in the libopenmpt API examples.
* Various playback improvements and fixes for OKT, IT and MOD.
### libopenmpt 0.2-beta13 (2015-08-16)
* [**Change**] The MSVC build system has been redone. Solutions are now
located in `build/vsVERSION/`.
* [**Bug**] get_current_channel_vu_left and get_current_channel_vu_right only
return the volume of the front left and right channels now.
get_current_channel_vu_rear_left and get_current_channel_vu_rear_right
do now actually work and return non-zero values.
* [**Bug**] Fix crashes and hangs in MED and MDL loaders and with some
truncated compressed IT samples.
* [**Bug**] Fix crash when playing extremely high-pitched samples.
* Completed C and C++ documentation
* Added new key for openmpt::module::get_metadata, "message_raw", which
returns an empty string if there is no song message rather than a list of
instrument names.
* in_openmpt: Support for compiling with VS2008.
* xmp-openmpt: Support for compiling with VS2008.
* in_openmpt: Add a more readable file information window.
### libopenmpt 0.2-beta12 (2015-04-19)
* Playback fix when row delay effect is used together with offset command.
* A couple of fixes for the seek.sync_samples=1 case.
* IT compatibility fix for IT note delay.
* ProTracker MOD playback compatibility improvement.
### libopenmpt 0.2-beta11 (2015-04-18)
* [**Change**] openmpt_stream_seek_func() now gets called with
OPENMPT_STREAM_SEEK_SET, OPENMPT_STREAM_SEEK_CUR and
OPENMPT_STREAM_SEEK_END whence parameter instead of SEEK_SET, SEEK_CUR and
SEEK_END. These are defined to 0, 1 and 2 respectively which corresponds to
the definition in all common C libraries. If your C library uses different
constants, this theoretically breaks binary compatibility. The old
libopenmpt code, however, never actually called the seek function, thus,
there will be no problem in practice.
* [**Change**] openmpt123: When both SDL1.2 and PortAudio are available,
SDL is now the preferred backend because SDL is more widespread and better
tested on all kinds of different platforms, and in general, SDL is just
more reliable.
* [**Bug**] libopenmpt now also compiles with GCC 4.3.
* libopenmpt now supports PLM (Disorder Tracker 2) files.
* Various playback improvements and fixes for IT, S3M, XM, MOD, PTM and 669
files.
### libopenmpt 0.2-beta10 (2015-02-17)
* [**Change**] Makefile configuration filenames changed from
`build/make/Makefile.config.*` to `build/make/config-*.mk`.
* [**Change**] libopenmpt for Android now supports unmo3 from un4seen. See
`build/android_ndk/README.AndroidNDK.txt` for details.
* [**Bug**] Fix out-of-bounds read in mixer code for ProTracker-compatible
MOD files which was introduced back in r4223 / beta6.
* Vibrato effect was too weak in beta8 and beta9 in IT linear slide mode.
* Very small fine portamento was wrong in beta8 and beta9 in IT linear slide
mode.
* Tiny IT playback compatibility improvements.
* STM playback improvements.
### libopenmpt 0.2-beta9 (2014-12-21)
* [**Bug**] libopenmpt_ext.hpp was missing from the Windows binary zip files.
### libopenmpt 0.2-beta8 (2014-12-21)
* [**Change**] foo_openmpt: Settings are now accessible via foobar2000
advanced settings.
* [**Change**] Autotools based build now supports libunmo3. Specify
--enable-unmo3.
* [**Change**] Support for dynamic loading of libunmo3 on MacOS X.
* [**Change**] libopenmpt now uses libltld (from libtool) for dynamic loading
of libunmo3 on all non-Windows platforms.
* [**Change**] Support for older compilers:
* GCC 4.1.x to 4.3.x (use `make ANCIENT=1`)
* Microsoft Visual Studio 2008 (with latest Service Pack)
(see `build/vs2008`)
* [**Change**] libopenmpt_ext.hpp is now distributed by default. The API is
still considered experimental and not guaranteed to stay API or ABI
compatible.
* [**Change**] xmp-openmpt / in_openmpt: No more libopenmpt_settings.dll.
The settings dialog now uses a statically linked copy of MFC.
* [**Bug**] The -autotools tarballs were not working at all.
* Vastly improved MT2 loader.
* Improved S3M playback compatibility.
* Added openmpt::ext::interactive, an extension which adds a whole bunch of
new functionality to change playback in some way or another.
* Added possibility to sync sample playback when using
openmpt::module::set_position_* by setting the ctl value
seek.sync_samples=1
* Support for "hidden" subsongs has been added.
They are accessible through the same interface as ordinary subsongs, i.e.
use openmpt::module::select_subsong to switch between any kind of subsongs.
* All subsongs can now be played consecutively by passing -1 as the subsong
index in openmpt::module::select_subsong.
* Added documentation for a couple of more functions.
### libopenmpt 0.2-beta7 (2014-09-07)
* [**Change**] libopenmpt now has an GNU Autotools based build system (in
addition to all previously supported ways of building libopenmpt).
Autotools support is packaged separately as tarballs ending in
`-autotools.tar.gz`.
* [**Bug**] The distributed windows .zip file did not include pugixml.
* [**Regression**] openmpt123: Support for writing WavPack (.wv) files has
been removed.
Reasoning:
1. WavPack support was incomplete and did not include support for writing
WavPack metadata at all.
2. openmpt123 already supports libSndFile which can be used to write
uncompressed lossless WAV files which can then be encoded to whatever
format the user desires with other tools.
### libopenmpt 0.2-beta6 (2014-09-06)
* [**Change**] openmpt123: SDL is now also used by default if availble, in
addition to PortAudio.
* [**Change**] Support for emscripten is no longer experimental.
* [**Change**] libopenmpt itself can now also be compiled with VS2008.
* [**Bug**] Fix all known crashes on platforms that do not support unaligned
memory access.
* [**Bug**] openmpt123: Effect column was always missing in pattern display.
### libopenmpt 0.2-beta5 (2014-06-15)
* [**Change**] Add unmo3 support for non-Windows builds.
* [**Change**] Namespace all internal functions in order to allow statically
linking against libopenmpt without risking duplicate symbols.
* [**Change**] Iconv is now completely optional and only used on Linux
systems by default.
* [**Change**] Added libopenmpt_example_c_stdout.c, an example without
requiring PortAudio.
* [**Change**] Add experimental support for building libopenmpt with
emscripten.
* [**Bug**] Fix ping-pong loop behaviour which broke in 0.2-beta3.
* [**Bug**] Fix crashes when accessing invalid patterns through libopenmpt
API.
* [**Bug**] Makefile: Support building with missing optional dependencies
without them being stated explicitely.
* [**Bug**] openmpt123: Crash when quitting while playback is stopped.
* [**Bug**] openmpt123: Crash when writing output to a file in interactive UI
mode.
* [**Bug**] openmpt123: Wrong FLAC output filename in --render mode.
* Various smaller playback accuracy improvements.
### libopenmpt 0.2-beta4 (2014-02-25)
* [**Bug**] Makefile: Dependency tracking for the test suite did not work.
### libopenmpt 0.2-beta3 (2014-02-21)
* [**Change**] The test suite is now built by default with Makefile based
builds. Use `TEST=0` to skip building the tests. `make check` runs the test
suite.
* [**Bug**] Crash in MOD and XM loaders on architectures not supporting
unaligned memory access.
* [**Bug**] MMCMP, PP20 and XPK unpackers should now work on non-x86 hardware
and implement proper bounds checking.
* [**Bug**] openmpt_module_get_num_samples() returned the wrong value.
* [**Bug**] in_openmpt: DSP plugins did not work properly.
* [**Bug**] in_openmpt/xmp-openmpt: Setting name for stereo separation was
misspelled. This version will revert your stereo separation settings to
default.
* [**Bug**] Crash when loading some corrupted modules with stereo samples.
* Support building on Android NDK.
* Avoid clicks in sample loops when using interpolation.
* IT filters are now done in integer instead of floating point. This improves
performance, especially on architectures with no or a slow FPU.
* MOD pattern break handling fixes.
* Various XM playback improvements.
* Improved and switchable dithering when using 16bit integer API.
### libopenmpt 0.2-beta2 (2014-01-12)
* [**Bug**] MT2 loader crash.
* [**Bug**] Saving settings in in_openmpt and xmp-openmpt did not work.
* [**Bug**] Load libopenmpt_settings.dll also from below Plugins directory in
Winamp.
* DBM playback improvements.
### libopenmpt 0.2-beta1 (2013-12-31)
* First release.
