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 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 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.
