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)

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 performances, 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.
