For fully detailed change log, please see the source repository directly. This
is just a high-level summary.

### libopenmpt 0.3.34 (2021-11-14)

 *  [**Bug**] Fixed various undefined behaviour found with ubsan.

 *  IMF: Change envelope interpretation to be more like in XM instead of IT and
    tighten header validation.
 *  MT2: Ignore incorrect drums chunk size in early MT2 files
    (fixes e.g. "A little Rock" by Csumi).
 *  MT2: Work around initial master volume of 0 used in some files that apply a
    fade-in a the song start using track automation that would stay silent
    forever otherwise (track automation is currently not supported).

 *  mpg123: Update to v1.29.2 (2021-10-23).

### libopenmpt 0.3.33 (2021-10-04)

 *  [**Sec**] Possible crash when loading malformed MDL files. (r15658)

 *  [**Bug**] Fixed various undefined behaviour found with ubsan.

 *  IT: Tremor command I11 erroneously behaved like I00 (use previous parameter)
    unless IT Old Effects were enabled.
 *  PTM: Panning was translated wrong in some edge cases.
 *  DBM: Echo enable effect parameter range checks were incorrect.

 *  in_openmpt: Song metadata is no longer reverted when viewing file info.

 *  mpg123: Update to v1.29.0 (2021-09-06).

### libopenmpt 0.3.32 (2021-08-22)

 *  [**Sec**] Possible crash with malformed modules when trying to access
    non-existent plugin slots FX251-FX255. (r15481, r15520, r15522)
 *  [**Sec**] Possible read beyond sample start after swapping to a sample with
    loop points set but not loop enabled. (r15501)
 *  [**Sec**] Fixed various possible crashes with malformed MMCMP files.
    (r15506, 15530)
 *  [**Sec**] MED: Possible read past end of file buffer by up to 3 bytes
    (r15508, 15510)

 *  Fixed excessive memory usage with files claiming to have an extremely high
    rows per beat count while also using tempo swing. Maximum rows per beat are
    now limited to 65536.
 *  STP: Avoid creating thousands of patterns when loading malformed files even
    though no more pattern data can be read.

 *  mpg123: Update to v1.28.2 (2021-07-12).
 *  stb_vorbis: Update v1.22 commit 5a0bb8b1c1b1ca3f4e2485f4114c1c8ea021b781
    (2021-07-12).

### libopenmpt 0.3.31 (2021-07-04)

 *  S3M: Only for OPL instruments the high sample rate bits should be ignored;
    for PCM instruments they are clamped to 65535 Hz.
 *  MOD: Do not apply ProTracker loop length quirk to MODs that could have been
    made with Scream Tracker (fixes Soul-O-Matic by Purple Motion).
 *  AMF (DSMI): Format revisions 1 and 9, as well as early (technically
    malformed) revision 10 files, are now supported. Surround panning commands
    and instrument number without note are now converted correctly.
 *  AMF (DSMI): Patterns and samples were not read correctly in some files
    (e.g. AVOID.AMF).
 *  GDM: Correctly import extra-fine portamentos.

 *  mpg123: Update to v1.28.0 (2021-06-05).
 *  ogg: Update to v1.3.5 (2021-06-04).
 *  stb_vorbis: Update v1.21 commit 8e51be04dc7dcee462e1f09e410faceab52cc6d2
    (2021-07-02).

### libopenmpt 0.3.30 (2021-05-16)

 *  MPTM: In some MPTM files with OPL instruments, specifically if sample
    compression was turned on in OpenMPT, reading extended song properties
    failed. This is specially problematic because that means that there was no
    warning was logged that those files were made with a more recent version of
    OpenMPT than the playback core in libopenmpt 0.3.
 *  ProTracker 3.6 doesn't support sample swapping. It is now disabled when
    loading a ProTracker 3.6 IFF module.
 *  669: Reject files that contain any pattern tempo higher than 15. 
 *  Reduce memory consumption of malformed XPK-compressed files.

 *  mpg123: Update to v1.27.2 (2021-05-08).

### libopenmpt 0.3.29 (2021-04-11)

 *  [**Sec**] Possible null-pointer dereference read caused by a sequence of
    `openmpt::module::read`, `openmpt::module::set_position_order_row` pointing
    to an invalid pattern, and another `openmpt::module::read` call. To trigger
    the crash, pattern 0 must not exist in the file and the tick speed before
    the position jump must be lower than the initial speed of the module.
    (r14532)

 *  [**Bug**] libopenmpt 0.3.28 broke seeking in some subsongs.
 
 *  The built-in LFO plugin did not load the correct initial LFO frequency.
 *  libopenmpt_ext `play_note` was cutting of channels even when there were
    plenty of free channels to use.

 *  mpg123: Update to v1.26.5 (2021-03-22).

### libopenmpt 0.3.28 (2021-03-20)

 *  Fixed excessive memory consumption with malformed files in various formats.

### libopenmpt 0.3.27 (2021-03-14)

 *  AMS: Avoid allocating excessive amount of memory for compressed song message
    in malformed files.
 *  S3M: Some samples were imported with a too high sample rate if module was
    saved with Scream Tracker 3.

 *  vorbis: Update to v1.3.7 (2020-07-04).

### libopenmpt 0.3.26 (2021-01-31)

 *  [**Bug**] stb_vorbis: Fix decoding of Vorbis streams without comments which
    affected most Vorbis samples since stb_vorbis v1.20.

 *  DMF: Improve import of finetune effect with parameters larger than +/-15.

 *  mpg123: Update to v1.26.4 (2020-12-24).

### libopenmpt 0.3.25 (2020-11-29)

 *  AMS: An upper bound for uncompressed sample size is now established to
    avoid memory exhaustion from malformed files.
 *  MO3: Avoid certain ModPlug hacks from being fixed up twice, which could lead
    to e.g. very narrow pan swing range for old OpenMPT IT files saved with a
    recent MO3 encoder version. 
 *  IMF: Instrument sample mapping was off by one octave, notable in the guitar
    part of Astaris by Karsten Koch.
 *  PLM: Percentage offset (Mxx) was slightly off.

### libopenmpt 0.3.24 (2020-08-30)

 *  PP20: The first few bytes of some files were not decompressed properly,
    making some files unplayable (depending on the original format).

### libopenmpt 0.3.23 (2020-07-26)

 *  [**Bug**] `libopenmpt/libopenmpt.h` failed to compile with
    `LIBOPENMPT_NO_DEPRECATE` defined.

 *  IT: Global volume slides with both nibbles set preferred the "slide up"
    nibble over the "slide down" nibble in old OpenMPT versions, unlike other
    slides. Such old files are now imported correctly again.
 *  IT: Fixed an edge case where, if the filter hit full cutoff / no resonance
    on the first tick of a row where a new delayed note would be triggered, the
    filter would be disabled even though it should stay active. Fixes trace.it
    by maddie.
 *  XM: Out-of-range arpeggio clamping behaviour broke in OpenMPT 1.23.05.00.
    The arpeggios in Binary World by Dakota now play correctly again.
 *  S3M: Support old-style sample pre-amp value in very early S3M files.
 *  S3M: Only force-enable fast slides for files ST 3.00. Previously, any S3M
    file made with an ST3 version older than 3.20 enabled them.
 *  M15: Improve tracker detection heuristics to never assume SoundTracker 2.0
    if there is a huge number of Dxx commands, as that is a definite hint that
    they should be treated as volume slides. Fixes Monty On The Run by
    Master Blaster.

 *  mpg123: Update to v1.26.3 (2020-07-16).
 *  stb_vorbis: Update v1.20 commit b42009b3b9d4ca35bc703f5310eedc74f584be58
    (2020-07-13).

### libopenmpt 0.3.22 (2020-05-24)

 *  IT: Disable retrigger with short notes quirk for modules saved with
    Chibi Tracker, as it does not implement that quirk.
 *  MOD: Fix early song ending due to ProTracker pattern jump quirk
    (EEx + Dxx on same row) if infinite looping is disabled.
    Fixes Haunted Tracks.mod by Triace.
 *  MOD: Vibrato type "ramp down" was upside down.

 *  stb_vorbis: Update to v1.19 commit 37b9b20fdec06c75a0493e0bb59e2d0f288bfb51
    (2020-02-05).

### libopenmpt 0.3.21 (2020-04-13)

 *  IT: Vibrato was too fast in Old Effects mode since libopenmpt 0.3.
 *  XM: Treat 8bitbubsy's FT2 clone exactly like Fasttracker 2 with respect to
    compatibility and playback flags. For example, FT2 Pan Law was not applied.
 *  DMF: Some files had a wrong tempo since libopenmpt 0.2.5705-beta15.

### libopenmpt 0.3.20 (2019-10-30)

 *  mpg123: Update to v1.25.13 (2019-10-26).

### libopenmpt 0.3.19 (2019-10-02)

 *  [**Sec**] libmodplug: C API: Limit the length of strings copied to the
    output buffer of `ModPlug_InstrumentName()` and `ModPlug_SampleName()` to 32
    bytes (including terminating null) as is done by original libmodplug. This
    avoids potential buffer overflows in software relying on this limit instead
    of querying the required buffer size beforehand. libopenmpt can return
    strings longer than 32 bytes here beacuse the internal limit of 32 bytes
    applies to strings encoded in arbitrary character encodings but the API
    returns them converted to UTF-8, which can be longer. (reported by Antonio
    Morales Maldonado of Semmle Security Research Team) (r12131)
    ([CVE-2019-17113](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17113))
 *  [**Sec**] libmodplug: C++ API: Do not return 0 in
    `CSoundFile::GetSampleName()` and `CSoundFile::GetInstrumentName()` when a
    null output pointer is provided. This behaviour differed from libmodplug and
    made it impossible to determine the required buffer size. (r12132)

### libopenmpt 0.3.18 (2019-09-23)

 *  J2B: Ignore notes with non-existing instrument (fixes Ending.j2b).

 *  mpg123: Update to v1.25.12 (2019-08-24).
 *  ogg: Update to v1.3.4. (2019-08-31).
 *  flac: Update to v1.3.3. (2019-08-04).

### libopenmpt 0.3.17 (2019-08-10)

 *  [**Bug**] Compilation fix for NO_PLUGINS being defined.

 *  Breaking out of a sustain loop through Note-Off sometimes didn't continue in
    the regular sample loop.
 *  Seeking did not stop notes playing with XM Key Off (Kxx) effect.

 *  mpg123: Update to v1.25.11 (2019-07-18).
 *  miniz: Update to v2.1.0 (2019-05-05).
 *  stb_vorbis: Update to v1.17 (2019-08-09).

### libopenmpt 0.3.16 (2019-04-07)

 *  [**Bug**] Channel VU meters were swapped.

 *  Startrekker: Clamp speed to 31 ticks per row.

 *  miniz: Update to v2.0.8 (2018-09-19).
 *  stb_vorbis: Update to v1.16 (2019-03-05).

### libopenmpt 0.3.15 (2019-01-22)

 *  [**Sec**] DSM: Assertion failure during file parsing with debug STLs
    (r11210).
    ([CVE-2019-14382](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-14382))
 *  [**Sec**] J2B: Assertion failure during file parsing with debug STLs
    (r11217).
    ([CVE-2019-14383](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-14383))

### libopenmpt 0.3.14 (2019-01-06)

 *  [**Bug**] MSVC project files in Windows source package lacked additional
    files required to build DLLs.

 *  Do not apply Amiga playback heuristics to MOD files that have clearly been
    written with a PC tracker.
 *  SFX: Work around bad conversions of the "Operation Stealth" soundtrack by
    turning pattern breaks into note stops.
 *  MO3: Apply playback changes based on "ModPlug-made" header flag.

### libopenmpt 0.3.13 (2018-10-21)

 *  [**Sec**] Crash with malformed MED files (r10904).
    ([CVE-2018-20860](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20860))

 *  Transposed samples in AMF ASYLUM modules were not played correctly.
 *  Notes triggered by libopenmpt_ext play_note could be played with a panbrello
    effect if the same virtual channel was previously used with panbrello.
 *  Clicks when stopping channels that didn't end at zero volume.
 *  XM: Do not import non-standard commands N and M as channel volume commands.

### libopenmpt 0.3.12 (2018-09-24)

 *  [**Bug**] openmpt123: Prevent libsdl2 and libsdl from being enabled at the
    same time because they conflict with each other.
 *  [**Bug**] Make building the JavaScript package work with Emscripten version
    1.38.1 or later by disabling WebAssembly generation which generates a
    different set of output files. Emscripten 1.38.1 changed the default to
    WebAssembly.
 *  [**Bug**] libmodplug: Setting `SNDMIX_NORESAMPLING` in the C++ API always
    resulted in linear interpolation instead of nearest neighbour.

 *  [**Change**] The old Emscripten configuration which is compatible with
    Emscripten before 1.38.0 has been renamed to `CONFIG=emscripten-old`.

 *  libopenmpt now compiles without warnings with GCC 8.

 *  Jump commands on the same row as the end of a pattern loop covering the
    restart position of the module could cause the module to loop even when
    looping was disabled.
 *  MO3: Reject overly long MP3 and Vorbis samples.
 *  `play_note` from the libopenmpt_ext interface sometimes silenced the start
    of a triggered sample.

### libopenmpt 0.3.11 (2018-07-28)

 *  [**Sec**] Crash with some malformed custom tunings in MPTM files (r10615).
    ([CVE-2018-20861](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20861))

 *  Channels whose volume envelope was playing at volume 0 while being moved to
    a NNA background channel were cut off completely since libopenmpt 0.3.8.
 *  AMF (ASYLUM): Convert 7-bit panning to 8-bit panning for playback.

### libopenmpt 0.3.10 (2018-06-17)

 *  [**Bug**] Internal mixer state was not initialized properly when initially
    rendering in 44100kHz stereo format.
 *  [**Bug**] AMF: Undefined behaviour in loader code could lead to files
    playing silent.

 *  Switching between instruments with portamento did not update the NNA
    settings for the new instrument.
 *  FAR: Properly import volume commands.

### libopenmpt 0.3.9 (2018-04-29)

 *  [**Sec**] Possible write near address 0 in out-of-memory situations when
    reading AMS files (r10149).
    ([CVE-2018-11710](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-11710))

 *  [**Bug**] openmpt123: Fixed build failure in C++17 due to use of removed
    feature `std::random_shuffle`.

 *  STM: Having both Bxx and Cxx commands in a pattern imported the Bxx command
    incorrectly.
 *  STM: Last character of sample name was missing.
 *  Speed up reading of truncated ULT files.
 *  ULT: Portamento import was sometimes broken.
 *  The resonant filter was sometimes unstable when combining low-volume
    samples, low cutoff and high mixing rates.

### libopenmpt 0.3.8 (2018-04-08)

 *  [**Sec**] Possible out-of-bounds memory read with IT and MO3 files
    containing many nested pattern loops (r10028).
    ([CVE-2018-10017](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-10017))

 *  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.

### libopenmpt 0.3.7 (2018-03-11)

 *  [**Bug**] libopenmpt did not build with NDK r13b on armeabi due to missing
    `-latomic`.
 *  [**Bug**] xmp-openmpt: Sample rate and number of output channels were not
    applied correctly when using per-file settings.

 *  [**Change**] foo_openmpt: foo_openmpt is now packaged as a fb2k-component
    package for easier installation.

 *  IT: More accurate song length calculation for pattern loops that have no
    start command and are following another pattern loop.
 *  IMF: Filter cutoff was upside down and the cutoff range was too small.
 *  MED: Correctly import patterns with less channels than the maximum used
    amount. Import "STP" note stop command.
 *  DBM: Key Off and Set Envelope Position were imported incorrectly.
    High sample offset (E7x) is now supported.
 *  DIGI / DBM: Arpeggio should not return to base note at end of row.
 *  Some filter changes through MIDI macros were not applied if the note volume
    was set to 0 on the same row.

### libopenmpt 0.3.6 (2018-02-03)

 *  [**Sec**] Possible out-of-bounds memory read with malformed STP files.
    (r9576)
    ([CVE-2018-6611](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6611))

 *  [**Bug**] Small memory leak with malformed STP files.

 *  STM: Accurate emulation of Scream Tracker 2 tempo mode.
 *  STM: Better support for early format revisions (no such files have been
    found in the wild, though).
 *  Fine volume slides are now supported when seeking with seek.sync_samples=1
    enabled.

### libopenmpt 0.3.5 (2018-01-28)

 *  [**New**] Support MOD files from the Inconexia demo by Iguana.
 *  [**Bug**] xmp-openmpt: Saved settings were not applied instantly.

 *  XM E60 loop bug was not considered in song length calucation.
 *  Tighten M15 and MOD file rejection heuristics.
 *  J2B: Ignore frequency limits from file header. Fixes Medivo.j2b, broken
    since libopenmpt-0.2.6401-beta17.
 *  ParamEq plugin center frequency was not limited correctly.
 *  libopenmpt_ext C API was not included in the documentation.

### libopenmpt 0.3.4 (2017-12-17)

 *  IT: Fix broken volume envelopes with negative values as found in breakdwn.it
    by Elysis.

### libopenmpt 0.3.3 (2017-11-19)

 *  [**New**] foo_openmpt: foo_openmpt now also works on Windows XP.

 *  [**Bug**] All VS2015 and VS2017 project files targetting Windows XP did not
    set compiler option `/Zc:threadSafeInit-` which caused at least the player
    plugins `in_openmpt` and `xmp-openmpt` to fail to load.

### libopenmpt 0.3.2 (2017-11-04)

 *  [**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 .

 *  [**Change**] Windows bin and dev release packages now use zip archives
    instead of 7z archives as it had originally been intended for the 0.3.0
    release.
 *  [**Change**] openmpt123: The following combinations of options are now
    deprecated because they made no real sense in the first place:
    `--render --output`, `--ui --output-type`, `--batch --output-type`

 *  [**Bug**] libopenmpt did not build on Android NDK 15c (and possibly
    other versions between 12b and 15c as well).

 *  IT: In Compatible Gxx mode, allow sample changes next to a tone portamento
    effect if a previous sample has already stopped playing.
 *  MOD: Slides and delayed notes are executed on every repetition of a row with
    row delay (fixes "ode to protracker").

### libopenmpt 0.3.1 (2017-09-28)

 *  [**Bug**] Windows: libopenmpt resource did not compile for release versions.

### libopenmpt 0.3.0 (2017-09-27, not released)

 *  [**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.

 *  [**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.
