4.7.0 (20260225):
	Changes by Alice Rowan:
	- Increase maximum sampling rate (XMP_MAX_SRATE) to 768000.
	  This increases XMP_MAX_FRAMESIZE to 384000. The tick buffers are now
	  allocated using the player-provided rate instead of XMP_MAX_FRAMESIZE:
	  the frame info buffer may also be much smaller than XMP_MAX_FRAMESIZE.
	  In case of existing software misusing the old XMP_MAX_FRAMESIZE, the
	  minimum value for mixer_data->total_size is the old XMP_MAX_FRAMESIZE
	  for now.
	- xmp_seek_time now always seeks (even if the position is the same
	  as the current position) and uses the start row detected by the scan.
	- New function: xmp_seek_time_frame, which attempts to seek to the time
	  requested by the caller within frame precision. This is achieved by
	  using xmp_seek_time then repeatedly calling xmp_play_frame until the
	  *next* frame contains the caller-requested time. The caller can then
	  use xmp_play_frame/xmp_play_buffer to render the requested frame.
	  WARNING: this is more computationally expensive than xmp_seek_time.
	- New function: xmp_set_tempo_factor_relative, to set a relative
	  tempo factor without clobbering the module's tempo factor.
	- New function: xmp_get_tempo_factor, to get the base tempo factor
	  set by loading a module or by xmp_set_tempo_factor.
	- New function: xmp_get_tempo_factor_relative, to get the relative
	  tempo factor set by xmp_start_player/xmp_set_tempo_factor_relative.
	- New API define: XMP_FORMAT_32BIT for xmp_start_player to enable
	  32-bit integer output.
	- New API define: XMP_INST_NO_DEFAULT_PAN for xmp_subinstrument::pan
	- New API defines: XMP_MARK_SKIP and XMP_MARK_END for xmp_module::xxo
	- Add support for Pack-Ice ("Ice!", "ICE!") depacking.
	- Add support for Software Visions DMF (Apocalypse Abyss MOD variant).
	- Replace kernel list helper in iff.c with custom list management
	  to fix numerous otherwise unfixable KallistiOS redefinition warnings.
	- All internal module time/duration calculations are now in doubles
	  (fixes off-by-one module time on final tick of some modules).
	- IFF format loading is now more permissive toward errors in the IFF
	  tag structure, fixing some broken modules that would load for 64-bit
	  Linux builds but not for Windows.
	- Fix sample name, restart position, note 0 loading, and pattern count
	  calculation for Images Music System modules.
	- Fix XM volume effects cxx/dxx accidentally having effects memory.
	- Fix FAR volume and note edge cases (Prescience/aurora.far pos. 16).
	- Fix Real Tracker RTM maximum pattern row count, various effects
	  translations, initial panning and sample panning, sample base volume,
	  non-delta coded samples, and instrument flags.
	- Correct default of sample default panning values to -1 (no default
	  panning) for most module formats.
	- Fix DigiBooster Pro sample default panning.
	- Fix DigiBooster Pro note 0x1f (key off) and misc. other tidying.
	- Fix Funktracker sample default panning.
	- Fix FunkTracker Fk** and DOS32 initial channel panning.
	- Fix FunkTracker notes 0x3d (partial fix) and 0x3e.
	- Fix FunkTracker injecting sample default volume into events, causing
	  most notes to play at slightly wrong volumes.
	- Fix Galaxy Music System 4.0 sample default panning.
	- Fix Imago Orpheus IMF sample default panning.
	- Fix Imago Orpheus IMF note 255 (no note, not key off).
	- Fix Imago Orpheus IMF Ixx/Jxx/Kxx/Lxx memory, Axy when x and y != 0.
	- Fix Liquid Tracker LIQ sample default panning.
	- Simplify read_event_mod, read_event_st3, read_event_ft2,
	  read_event_med sample default volume handling.
	- MED "hold symbols" now apply the referenced instrument's default
	  volume for modules from OctaMED 3.00+ and don't apply any default
	  volume for modules from prior versions.
	- Fix MED hold/decay implementation and add support for command 8.
	- Fix MED synthetic instrument waveform table speeds.
	- Fix MED module duration for modules using command 1E (pattern delay).
	- Fix MED loading of InstrExt data when s_ext_entrsz is 2.
	- MED: only load long repeat fields for MMD3 modules.
	- Anticlick decay curves are now applied after IT note cut, DCA note
	  cut, IT effect S70 (etc.), and API-requested position changes.
	- XM, MOD: remove QUIRK_FINEFX from QUIRKS_FT2.
	- XM: channel fade rate is only copied from the instrument on rows
	  with note + ins. + no toneporta/K00.
	- XM: zero-length samples cut the channel like invalid instruments.
	- XM: do not cut on a no-instrument key off note if the preceding
	  instrument was invalid.
	- XM: previous instrument's sample default volume is now applied for
	  invalid instrument numbers beside a key off note.
	- XM: previous instrument's sample default panning is now applied for
	  invalid instrument numbers.
	- XM: apply default volume, panning, and instrument fade rate for
	  active invalid instruments.
	- XM: invalid instrument numbers now reset the envelope positions.
	- XM: valid instrument numbers with no note no longer set xc->ins,
	  which would cause notes to play with the wrong instrument envelopes
	  and could cause subsequent no-note instruments or invalid
	  instruments to apply the wrong instrument's volume/panning.
	- XM: rows with an instrument number and K00 no longer reset fadeout.
	- XM: apply QUIRK_FT2BUGS to Fasttracker II clone modules.
	- XM: reimplement Fasttracker II note delay effect.
	- XM: FT2 tremor now resets on all delay rows, does not reset on
	  instrument number + K00 rows, and is suppressed by instrument default
	  volume and Cxx in cases where it is not reset. FT2 tremor no longer
	  updates on note delay events before the delayed event is processed.
	- XM: load all keyoff notes as XMP_KEY_OFF (fixes keyoff + ins rows).
	- XM: keyoff without delay always immediately initiates fadeout, even
	  if there is a volume envelope. The old implementation would sometimes
	  delay the start of fadeout.
	- XM: keyoff without volume envelope sets the channel volume to 0
	  instead of setting fadeout to 0. This is now performed on the tick
	  where keyoff takes effect only (fixes volume effects not cancelling
	  the volume cut when they should have).
	- XM: fix volume column set volume effects resetting fadeout
	  (fixes Comic Bakery Remix position 35).
	- XM: fix Kxx persisting between rows and pattern delay interaction.
	- XM: fix note without ins# resetting fadeout position and state.
	- XM: detect more Modplug Tracker XMs via large unused instruments.
	- XM: handle out-of-range notes more closely to FT2.
	- XM: fix setting toneporta target with an active invalid instrument.
	- XM: implement FT2-style offset effect memory (QUIRK_FT2BUGS only).
	- Sum toneporta rates when toneporta is present in both effects slots
	  in an event; FT2 bug emulation for double toneporta now zeroes the
	  parameter of 3xx in the player instead of using a loader hack. This
	  doesn't affect Ultra Tracker toneporta.
	- XM: fix slow loads/OoMs caused by not verifying the MPT text length.
	- XMF: toneporta is identical to Ultra Tracker toneporta (slightly
	  affects max.xmf pos 13+, but the notes are out-of-tune either way).
	- Fix time tracking bugs in some complex pattern loop cases.
	- Fix time tracking bugs when Bxx+Dxx jumps within the same position.
	- Dxx (S3M/IT: Cxx) followed by Byy on the same row now jumps to pos Y
	  row X for S3M, IT, ModPlug XM, and Skale Tracker XM modules.
	- IT: fix importing channel initial panning for muted channels.
	- IT: fix playing instruments with samples >=120 in the key map.
	- MTM: fix pattern break hex parameter.
	- PTM: actually fix pattern break hex parameter.
	- STM: always use 0 for pattern break parameter (ST2 ignores it).
	- STM: import ST2 tempo values as both speed and BPM.
	- GDM: don't zero channel volume for muted channels.
	- Fix xmp_start_player not unmuting non-muted channels (regression
	  introduced in 4.5.0).

	- Fix out-of-bounds reads when xmp_next_position is used at the end of
	  a 256 position module.
	- Fix hangs when seeking to an end-of-module marker caused by these
	  positions getting assigned a non-existent sequence.
	- Document xmp_set_position/xmp_next_position/xmp_prev_position
	  interactions with xmp_stop_module/xmp_restart_module.
	- Fix stack underflow in Pha Packer loader (CVE-2025-47256).
	- Slight performance improvements for the Oktalyzer and SFX loaders.
	- Fix broken conversion of ProRunner 2.0 pattern data.
	- xmp_set_tempo_factor no longer alters frame time calculation for
	  xmp_get_frame_info. Frame time is now updated to account for the
	  new time factor after calling xmp_scan_module.
