update 0.5.13 (2021-11-14) to 0.5.15 (2021-12-23)
--- 0.5.15 ---
[Sec] Possible out-of-bounds read of stack-allocated array in malformed
AMS files. (r16243)
[Bug] Fixed various undefined behaviour found with ubsan.
IT: Even after libopenmpt 0.5.14 the filter reset logic was still not
100% identical to Impulse Tracker: A note triggered on tick 0 of a row
with a Pattern Delay effect still caused the filter to be reset on
repetitions of that row even though the note wasn’t retriggered.
MOD: Loosened VBlank timing heuristics so that the original copy of
Guitar Slinger from Dizzy Tunes II plays correctly.
mpg123: Update to v1.29.3 (2021-12-11).
--- 0.5.14 ---
[Sec] Possible out-of-bounds read in Chorus plugin with NaN plugin
parameters. Most implementations of the “fast math” compiler
optimizations will prevent this crash but it is not guaranteed. (r16096)
[Bug] Fixed undefined behaviour with custom tunings found with ubsan.
OPL: Improved channel allocation strategy when there are lots of faded-out notes.
MOD: Digital Tracker MODs have four unknown bytes right after the magic
bytes which seem to be ignored even by Digital Tracker itself. Just skip
over them.
The logic when to turn off the resonant filter was broken in some edge
cases since libopenmpt 0.5.1.
IMF: Implemented XE1-XE3 commands, which disable individual envelopes.
Command Nxy (cutoff slide + resonance) is now also partially supported
(only resonance for now).
IMF: Filter envelopes were upside down.
MTM: Omitting pattern loading through the load.skip_patterns ctl caused
sample data to be corrupted.
S3M: Ignore O00 commands in files created with Scream Tracker 3.00 and
3.01, as this command only gained effect memory in version 3.03.
STM: Use S3M-like sample swap behaviour.
XM: Disable arpeggio quirk for XMs made with Skale Tracker. Fixes
KAPTENFL.XM.
miniz: Update to v2.2.0 (2021-06-27).
minimp3: Update to commit 50d2aaf360a53653b718fead8e258d654c3a7e41 (2021-11-27).
