Third-Party Libraries
   [Mod] Update libvorbis (v1.3.6) and unrar (v5.6.2)

General

• Song cleanup can now merge identical patterns.
• Ogg Vorbis and Opus support is now built-in and no longer requires an external library for stream export.
• Add a new "MP3 (compatible)" export file type that is implemented only via libmp3lame and is the same as the old libmp3lame CBR mode with strictly ID3v1 tags only. The regular MP3 export mode uses more modern defaults for better audio quality.
• Added hidden setting Misc.DistinguishModifiers to distinguish between left and right modifiers (e.g. to create FT2-like play pattern shortcuts).

Pattern Editor

• Double-clicking an empty order list cell creates a new pattern.
• To make Data Entry more useful, it is now only applied to the first column type of selection, even if it spans several channels (e.g. if the selection starts in the volume column, only volume will be changed).
• Find & Replace can now find ranges of data (e.g. notes C-5 to D-6) and replace them also with relative values or percentages. PC events are now also fully supported by Find & Replace.
• When jumping around between patterns, plugin parameters affected by PC events are now updated.

Plugins

• Shift-clicking a plugin editor toggle button closes all other editors.
• OpenMPT now reads the VST plugin vendor. Searching for a plugin in the plugin manager also searches in the vendor names.
• When opening an instrument plugin editor, check if the currently selected instrument would be suitable input instrument for the plugin, rather than just the first instrument that uses this plugin.
• If available (on DirectX 9 and newer), DMO plugins now process in floating-point precision rather than 16-bit PCM.
• Plugin editor position is now restored properly on multi-monitor setups.
• The MIDI Input / Output plugin now sends MIDI Clock events. It is now directly integrated into OpenMPT and no longer shipped as a separate VST plugin.
• The DigiBooster Pro Echo DSP is now fully emulated and can also be used in other formats as a plugin.

Sample / Instrument Editor

• The resampler tool can now use any of OpenMPT's interpolation filters for resampling in addition to r8brain.
• Loop cross-fader now also works with sustain loops.
• Try to load SF2 instruments with left and right layer as stereo samples. Detuned SF2 samples are now finally fixed!
• Ogg Vorbis and Opus sample loading support.

Playback

• Instead of having one "compatible playback" per file, every playback quirk now has its own flag. This includes a dialog to edit these flags. These flags should not be edited manually, except for the "Set Defaults" functionality.
• For old files made with MPT / OpenMPT before v1.24, sample rates are now computed in periods again in linear slide mode. This fixes for example the drum line sample in Zanoma's "Late At Night". Similarly, old OpenMPT-made files that use portamento at speed 1 now sound as in OpenMPT 1.17 - 1.20 again.
• Each sequence now has its own restart position in the MPTM format.
• Parameter Extension (#xx) now also works with Position Jump command in the MPTM format, adding the possibility to jump order list items ? 256.
• Samples in MPTM files are now compressed by default (lossless IT compression).
• Extra fine portamento now works properly with custom tunings.
• Playing a sample at a sample rate close to the mix rate could lead to small clicks when using vibrato.
• If no instrument number was provided, New Note Action with empty sample slot and Duplicate Note Action sample checks were broken.
• Countless other playback fixes.

File Format Support

• Improved MT2 support.
• Support for SoundFX / MultiMedia Sound (SFX / MMS) and ProTracker 3.6 IFF-style modules has been added.
• Better tracker detection heuristics for Ultimate SoundTracker modules.
• MO3 support is now built right into OpenMPT, no longer requiring the closed-source UNMO3 on Windows 7 and newer.

There's more...Known Issues

• The plugin bridge is new and hasn't been tested very much yet. It is known that some plugins don't work in it at all. Custom plugin GUIs are known to not work in Wine. Please report any other issues you may be having with the plugin bridge!
• Far from perfect VST support (no buses for audio / MIDI routing, not all tracker effects are supported, etc...)
• Previewing samples from the tree view's file browser stops the playing module.
• Cannot preview soundfont instruments directly from the MIDI Library in the tree view.
• Excessive performance drop when dragging over the graphical parameter editor during playback.
• There is no really convenient way to find out what features of the tracker are supported by the original trackers (Impulse Tracker, Fasttracker 2, etc...) when working with those file formats...

Better tracker detection heuristics for Ultimate SoundTracker modules.
MO3 support is now built right into OpenMPT, no longer requiring the closed-source UNMO3 on Windows 7 and newer.

It is now possible to skip forward / backward in the song with the pattern navigation keyboard shortcuts and scroll wheel during playback if "follow song" is enabled.
ID3v2.4 tags were malformed in OpenMPT 1.25.03.00, leading to the first audio frame being skipped when playing the exported MP3 file.
The plugin gain control in the General tab was not accessible to screen readers.
Recording MIDI CCs from MIDI was broken in MPTM files since OpenMPT 1.25.01.00.
Opening the MIDI Mapping Dialog from a bridged plugin GUI could freeze the tracker.
Global time signature values exceeding 255 rows were not loaded (but saved) correctly.
Support for a few more MOD variants (CD61, FA04, FA06, FA08, NSMS and LARD magic bytes).
Fixed a few more crashes and hangs encountered in AMF, IMF and MT2 loaders (detected with afl).
Some MOD files were erroneously detected as 669 files.
MIDI Learn in the MIDI Mapping Dialog did not work when opening the dialog from a plugin editor.
Using key bindings in paths longer than 260 characters should now work properly.
Disabling "Repeat notes on hold" for all notes at once was broken.

General

Revamped General Tab
Path / Auto Save Settings
In MPTM, IT and XM files, it is now possible to specify the song artist. The default artist can be specified in the settings dialog.
In MPTM files, the default resampling can now be overridden. The dropdown box in the general tab is also accessible in other formats (so you can quickly change resampling without having to modify your normal playback settings), but won't be saved to the file.
Decimal tempos (e.g. 123.45 BPM) can now be used in the MPTM format.
Tempo Shuffle can be used in modern tempo mode to automatically increase or decrease the duration of individual rows of a beat to creat a shuffled / swing rhythm.
Letters 'd' and '+' can now be used in note names of custom tunings.
It is now possible to export to a sample slot rather than a file.
Experimental support for 14-bit MIDI controllers in the MIDI Mapper. Combinations of CC 0...31 and CC 32...63 now act as double-precision MIDI messages. I don't have a 14-bit MIDI controller, so if you can test this feature, feedback would be appreciated!
A default module format or template to use when creating a new module can now be specified in the settings dialog.
Hidden setting Misc.AllowMultipleCommandsPerKey can be used to allow more than one keyboard shortcut being bound to the same key combination (may do unexpected things with existing mappings with overlapping shortcuts such as IT-style "Play Row" on the 8 key, so beware).
Pattern Editor

In the order list, it is now also possible to just copy the order list pattern numbers instead of their content ("Copy Orders" in context menu or Ctrl+Shift+C by default).
Added option for smooth (tick-by-tick) pattern scrolling. This is still somewhat experimental and consumes more CPU than necessary at the moment, but should be optimized in the future.
Apply DNA and NNA settings to live note preview.
The effect visualizer window size is now remembered across sessions.
Tree view

Sample / instrument preview is now stopped using Note Cut / Off / Fade keys instead of automatically fading out after some seconds.
Plugins

Module instruments are now created automatically for newly added instrument plugins.
Added hidden setting "VST Plugins.EnableAutoSuspend" which activates plugin auto-suspension for all plugins (later, this will be configurable per plugin). If a plugin didn't emit any sound during the last four seconds, its sound output is automatically suspended. Mostly useful for bridged plugins to save on process calls.
When using the plugin bridge, MIDI events sent to 64-bit plugins or 64-bit OpenMPT do now work correctly.
A few more plugins do now work correctly in the plugin bridge.
Sample / Instrument Editor

Add Media Foundation (AAC, WMA, ASF, MP1, MP2, MP3, WAV-MSADPCM, ...) sample decoding support on Windows 7 and later.
Hovering the default and global volume fields now displays their attenuation in dB. Similarly, hovering the panning field shows its value in a more human-readable form.
Added dropdown menu to New button for duplicating samples.
Playback

A couple of playback behaviours have been changed and improved:
Instrument random variation is now applied to the velocity of notes sent to instrument plugins.
Tremor (Ixx) is now also supported for instrument plugins.
The NNA channel allocation algorithm has been finetuned to also take volume envelopes into account when running out of free channels.
When executing tone portamento with instruments with custom tunings and the sample doesn't change between the notes, re-apply the sample settings such as default volume and panning like with normal samples.
File Format Support

In S3M files not made with OpenMPT or Scream Tracker, support portamento between different samples again like in old versions of ModPlug Tracker (fixes k_vision.s3m).
Heuristically enable ProTracker 1/2 mode if 8xx commands seem likely to be used as sync markers rather than panning in 4-channel MODs.

General

Missing Samples Dialog
MIDI Mapping Dialog
ITP is dead, long live MPTM! No worries, your old ITP files can still be imported, but the clunky ITP format has been dropped in favour of some new features in the MPTM format: Instead of instruments, you can now keep references to external samples in your MPTM files, effectively reducing the file size even if a sample is shared by several instruments. The ITI instrument format has been extended in a similar way so that ITI files can now simply reference external sample files instead of directly embedding the sample data. Unlike in the ITP format, it is easy to mix external and internal samples in one file and relocate missing files.
Each song's window position and contents are now saved, so that you can continue right where you left off when reloading the file.
"Remove unused sample data" now also finds samples with identical stereo channels and offers to optimize them to mono.
Dropping a folder on OpenMPT that contains modules or VST plugins opens / registers them directly now.
Song length estimation can now show the length of all "hidden" subtunes in the current sequence.
Many small improvements in the audio output code again, also to improve performance on Wine systems.
Made the MIDI Mapping dialog's mapping list more human-readable.
Pattern Editor

Ctrl+(Shift+)Scroll wheel can now be used as a replacement for the "(Coarse) Data Entry" shortcuts.
Tree view

Further enhanced drag&drop functionality: Dropping a module or folder on the sample browser opens this module or folder for browsing, dropping a soundfont file on the upper part of the tree view adds it to the list of soundfonts.
Due to the change from external instruments in the ITP format to external samples in MPTM, "Set Path" and "Save" have been moved to samples. External samples are marked with [external], missing external samples are marked with [missing].
Sample waveforms can now be reloaded from disk (e.g. after editing a sample in an external application) if OpenMPT knows the sample's original path, e.g. after loading or saving it, or using MPTM's external sample feature.
Plugins

When adding a new plugin through the plugin manager that is missing from some open file, it is now automatically loaded and restored in that file.
"Randomize Parameters" now applies a customizable randomization factor - much more useful than completely random parameters.
Sample Editor

Resampling to any custom sample rate is now possible, thanks to the high-quality r8brain-free resampler.
Adjusting the sample frequency updates all playing notes' sample frequency immediately (only in IT and MPTM).
Custom background and selection colours.
Rearranging samples (e.g. through song cleanup or the tree view) no longer messes up the undo buffer history.
Instrument Editor

ITI instrument files can now contain external samples (like MPTM files, see above). Select "Impulse Tracker Instruments with external Samples" from the save dialog.
When previewing instruments with a fadeout value of 0, instantly stop them on key-up instead of letting them play forever.
The first instrument of a soundfont can now be loaded directly without registering the soundfont in OpenMPT. Useful for single-instrument soundfonts.
Playback

A couple of playback behaviours have been changed and improved:
S70 / S71 / S72 commands do now also work with instrument plugins. NNA / DCA settings are now applied to plugins assigned to sample-less instruments as well.
Smooth MIDI macros do now, to some extent, work with external MIDI messages. They interpolate from the previous Zxx or \xx parameter from the same channel to the new parameter.
In all mix modes since 1.17RC2, a way too long volume ramp (some times up to 100 times longer than the user-supplied ramp setup) was applied for extreme global volume changes. This is now disabled except for legacy 1.17RC2 mix mode.
Re-implemented stereo separation to be applied on the master mix. This means that it also works as expected with stereo samples and plugins now.
Linear frequency slide mode (in all formats except XM, which already worked as intended) has been re-implemented to fix some unwanted inaccuracies which can add up very quickly when using extra-fine slides.
File Format Support

Reverted XM compatibility export to always write out 256 order items, which should restore compatibility with a couple of players that were previously choking on OpenMPT's XM files.
Use "normal" compatible mix mode instead of FT2 panning mix mode for XM files that were compatibility-exported with OpenMPT 1.22 or older, and XM files made with other trackers that use linear panning.
Compatible playback mode for S3M: When enabled, OpenMPT emulates certain ScreamTracker quirks as it did until now (linked pattern effect memory and ignored effects on muted channels). Compatible mode is disabled automatically for files made with less compatible trackers. S3M files made with OpenMPT always have this mode enabled, and its state is not saved in S3M files.
Amiga frequency limits can now also be enforced in MOD files without activating ProTracker 1/2 mode.
Added loading support for a MOD variant introduced by SoundTracker 2.6 and Ice Tracker.
Completely rewrote MT2 loader. Some files that would previously not load properly do now load. Support for VST plugins, drum patterns and some extended MT2 pattern commands has been added.
There's more...
