fix possible PCM crash when using VERA
YM2612 fixes:
fix panning view on ExtCh channel 5
fix arp issue when using non-linear pitch
added a couple song flags:
Volume scaling rounds up: makes volume scaling round up (ceil) rather than being rounded down. useful for NES triangle.
Reset arpeggio effect position on new note: resets the arpeggio effect's position on each note.
improve NES DPCM sample mapping
now it resembles FamiTracker more
each note has DPCM pitch and initial delta counter value settings
improve icons for ADSR/LFO macro types
display chevrons if certain values are out of view in macro view
come on Furnace can do Game Boy
changed macOS license text so it tells you about "Furnace is damaged"
add effect to restart a macro (F7xx)
don't change the instrument type if it is unknown once it is loaded in the instrument editor
ZSM export: remember last sample played so that async pitch changes work
Virtual Boy changes
fix forceIns not working well
add static wave storage mode (only 5 waves)
it is unknown whether it is possible to change waveforms on the fly...
wavetable creation improvements
now it defaults to best size for current chip
displays a list of recommended sizes if there's more than one chip that supports waves
add "make me a drum kit" option
right click a sample in the sample list and select the option to make an instrument with sample map set to all samples
new export dialog
as of now the export options are displayed on a dialog by default
you can change this back to the previous look by going into Settings
make "change" button more notorious in chip manager
re-arranged some of the tabs in instrument editor
macOS: better default shortcuts
added "default author name" setting
PC speaker: added option to reset phase when the frequency changes
this option was added after determining that many recent motherboards do so :<
add a preliminary safe mode
is your graphics card not working? Furnace fails to start? Furnace crashes on start-up because you loaded the wrong font, your sound/graphics card's driver is buggy or something? then this mode is for you!
pass the -safemode parameter to Furnace, which starts it in safe mode (software rendering, no audio and fallback font only).
alternatively, pass -safeaudio if you still want audio output.
I was planning to make this mode automatic (start in safe mode after failed start-up) but testers ran into issues (especially when launching more than one Furnace instance). I will improve this and make it fully automatic soon...
pattern view improvements
the ++ button now allows you to have both effect columns buttons and pattern name fields visible.
channel group hints, which display which channels are tied together (e.g. for 4-op mode, pitch modulation and more).
channel status hints, displaying note on/off, vibrato/tremolo, slides, and other status.
make it more obvious when trying to preview an instrument which cannot be previewed when the song doesn't have a chip which takes in that instrument type
MIDI improvements
added a button in Settings to re-scan MIDI devices
finally: velocity response
the velocity curve power is now 2.0 by default, to match General MIDI velocity standard
program change pass-through: now you can use Furnace as a MIDI player of sorts
many MIDI input bug fixes, such as input not working if the MIDI device's output channel is too high
C64 improvements
ADSR macros
global volume and cutoff macros are now separate
unified Special macro, with test/gate/ring/sync settings
note: if you were using the former ring/sync and gate macros crazily (different loop points and all), this might break your song.
default envelope reset time is now 2 instead of 1
relative macros are now fine and less Mask-y
1Exy effect now updates envelope immediately
20xy/21xy effects to set AD or SR with a single effect
a brand-new X-Y oscilloscope
this displays two output channels (e.g. left and right) in a plot.
C140: added bank types (for VGM export)
"loop crossfade" option in sample editor
default not to write instrument name when saving instrument to a file
this way you don't end up with too many "Instrument 0"s
new color scheme "guru mode"
now you can edit every single color in the UI
color scheme import/export improvements
now it saves a couple related settings as well
no more having to manually set color scheme type after importing
added "select asset on load" setting
added stereo 86PCM presets
it is uncertain whether PC-9801-86 DACs were hard-panned or in mono
added ability to hide channels in the per-channel osc independently of the pattern
added option to disable DC offset correction
paste from OpenMPT!
add new FreeType font renderer
it has more settings than the current one
added early text export feature
still incomplete
Amiga accuracy improvements
now AM/PM work correctly
don't stop DMA until period timer is done
new OPL sound cores:
YM3812-LLE: low-level emulation of the OPL2 chip. very CPU intensive but 100% accurate.
YMF262-LLE: like YM3812-LLE but for OPL3. even more CPU intensive.
these cores are made by nukeykt based on die shots of the original chips.
ymfm: why not? this core is made by Aaron Giles.
added ESFM chip
this chip is like OPL3, but adds many features on top of it, like 4-op on all channels, detune and per-operator panning.
added PowerNoise chip
a fantasy sound chip created by The Beesh-Spweesh! and jvsTSX for the Hexheld fantasy video game console, employing LFSR-based synthesis.
many doc updates
demo song updates
including songs from the Virtual Boy and ESFM demo song contests!

Changelog:
fix a major oversight in the new config system
there still was a chance that a corrupted config file would be loaded...
fix a major performance regression in audio playback
massive documentation updates - thanks to Electric Keet!
documentation is now in doc rather than papers/doc. this should make it easier to find.
ZSM export improvements
MooingLemur has implemented an unofficial but updated and backwards-compatible extension to this format, allowing VERA PCM!
additionally, EExx (external command) is now written during export, allowing you to use it for things like synchronizing with graphics.
new OpenGL and DirectX 11 render backends
prior to this change, Furnace used SDL Renderer for the UI
now Furnace will use DirectX 11 by default on Windows and OpenGL on Linux
you may see performance and reliability improvements
if it fails (e.g. because your card isn't compatible), it will fall back to the SDL Renderer backend a bug has been found in where it won't do this. I will release a hotfix.
per-channel osc improvements:
fix for YM2612 variants
fix YM2612 DualPCM chan osc
fix YM2612 DAC chan osc
don't hide title bar
add ability to change amplitude
add customizable labels
fix osc not being clipped to boundaries
lots of volume balancing
built-in file picker improvements:
finally fix sorting
sometimes it would change sort orientation randomly
sometimes it would not sort at all
sort by name didn't work when set to descending
replace the "reset path" button with a "home" button
search bar has more room to breathe
fix files with non-ASCII characters being displayed as "unknown type" and not having size/date information
now you can press Escape to cancel and quit the file picker
add a "push entire channel when inserting/backspac'ing" settings
on by default
VGM export fixes:
fix loop trail still being added when loop option is off
fix NES DPCM not working
cap streams to 44100Hz since VGMPlay doesn't like higher frequencies
Wayland fixes:
fix scaling factor detection when full-screen is on
fix mouse input being totally wrong at times
POKEY changes:
fix E5xx effect when using non-linear pitch
add a new effect for enabling two-tone mode
sample editor improvements
buttons now re-arrange when there isn't enough space
warnings that will let you know when a sample is outside of a chip's specs
use rate instead of compat rate when saving sample as .wav
"Apply filter" now displays cutoff parameters as input boxes instead of sliders
add option to select a different SDL audio driver
use it if you experience problems when using the default (in the case of Windows, it is WASAPI).
C64 changes
the default core is now reSID again. sorry.
reSIDfp's CPU usage is too high to be the default, despite its unmatched accuracy
add a "key priority" system which prioritizes the last used channel's global parameters (filter and volume)
fix reSIDfp envelope reset being inconsistent
new dSID core featuring low CPU usage
improve start-up time when not using reSIDfp
tiny playback optimization when a chip is silent
colorize destructive operations
fix .dmf not saving if it was made with 1.1.8

fix pattern editor focus when selecting instrument
improve start-up performance
add 8-bit dither option
fix one digit effect setting making effect 10xx glitch the pattern view
fix tremolo breaking when turned off
update Dear ImGui to 1.89 and SDL to 2.28

fix asset names carrying over another asset when the current asset name was being edited and another was selected in the list
you can no longer game-end-glitch TAS this tracker
if the FPS is too low and the intro is enabled, there is a minimal possibility you could load the intro song by exiting as soon as the intro started
fix atari breakbeat demo song
MIDI output: don't spam logs on error
move delete sample button to the right in sample list to prevent accidental clicks
